Voyager 2, A Portrait Before The Farewell

  • Voyager 2, A Portrait Before The Farewell


    Well, just four days after the deat- of Elvis, on August 20...from the Cape Canaveral base, the Voyager 2 mission left!
    43 years have passed, a lifetime...and yet since then Voyager has still been traveling, and still sending signals from ever more remote distances.
    It is the oldest of all of those still operational, but now perhaps it is time to say goodbye.
    Let's see why retracing its entire history.

    Business Enquiries:
    Pasadena, USA, summer 1964 at the Jet Propulsion Laboratory.
    In view of future space missions conducted with automatic probes, the young aerospace engineer Gary Flandro (1934) is assigned the task of studying new trajectories for the exploration of the external solar system.
    And Flandro does his job very well, so much so that he discovered that in a few years there would be an alignment between the outer planets that would allow a probe launched towards Jupiter to fly over Saturn, Uranus, and Neptune, only using the gravitational slingshot effect of each planet to reach the next; thus reducing from 40 to 10 years the time to complete the Grand Tour, as it was then called the tour of the outer solar system.
    But it must be done soon... that particular alignment occurs in fact only every 175 years, and to take full advantage of the favorable moment the probe must be launched in a period between 1976 and 1980.
    Flandro's study, published in 1965, makes a lot of sensation in the environment, and in 1969 it originates a first NASA mission proposal called Planetary Grand Tour, later canceled for budgetary reasons; and then the one for the launch of two twin probes generically called Mariner 11 and 12 (only in 1977 the spacecraft would have received the name of Voyager 1 and Voyager 2), the first one directed to Jupiter and Saturn and the second one charged to realize the Grand Tour desired by Flandro, that is: Jupiter, Saturn, Uranus, and Neptune!
    In the same year, the JPL proposed the construction of the probes, following the design phase begun in 1966, but it will not be easy ... In those years there were still many uncertainties about the obstacles that a spacecraft could encounter in crossing a region of the solar system that had not yet been explored.

    Some scientists, for example, believed that the asteroids of the main belt were so numerous that they prevented a spacecraft from crossing unharmed. Of great help in understanding that the danger was there, but much overestimated, were the Pioneer probes 10 and 11, which launched respectively on March 2, 1972, and April 5, 1973, would have been the forerunner for the Voyager.
    To make a long story short, after eight years of changes to the scientific and engineering load, Voyager 2 was launched from Cape Canaveral at 14:29 (universal time) on Saturday, August 20, 1977.
    About two years later, on July 9, 1979, the probe reaches the minimum distance from Jupiter, flies over the planet, and is diverted towards Saturn; receiving also a push (thanks to the slingshot effect) that increases its speed to reach Saturn more quickly.
    So Voyager 2 reaches the minimum distance from Saturn on August 26th, 1981, and from there it is diverted and accelerated towards Uranus, which flies over on January 24th, 1986; and, finally, from Uranus, it is directed towards Neptune, the remote planet that the probe reaches on August 25th, 1989.
    Carried out the primary mission, namely that of the Grand Tour of the four gas giants, the glorious spacecraft arrived at over 30 astronomical units of distance (equivalent to 4.5 billion kilometers) is assigned the Voyager Interstellar Mission.

  • Voyager 2 Finds Space Is More Dense Outside the Solar System


    PASADENA, CALIFORNIA — The Voyager spacecraft have found that space is more dense outside the Solar System, according to research published in the journal Astrophysical Letters.

    NASA’s Voyager 2 crossed into interstellar space in November of 2018 after a 41-year voyage. Its twin, Voyager 1, entered interstellar space at a different location in 2012.

    The authors of the study write that the increase in density detected by the Voyager spacecraft could be due to interstellar magnetic fields becoming stronger as they approach and drape over the heliopause.

    Alternatively, the material blown by the interstellar wind might slow down and build up as it approaches the heliopause.

    More data is needed from the two Voyagers to try to untangle this mystery. However, as the authors of the study note, “It is not certain whether the Voyagers will be able to operate far enough to distinguish between these two classes of models.”

  • Voyager 2 Has Found Something Weird In Outer Space!


    Traveling at a distance of over 11.2 billion miles from the Earth, Voyager 2 spacecraft has found something weird in outer space. It has found that the density of outer space is increasing. This has challenged the notion that space is a vacuum.

    Voyager 2 was launched in July 1977 as a part of NASA's Voyager Program. During its solar system voyage, Voyager 2 explored Jupiter, Saturn, Uranus, and Neptune. In 2018, Voyager 2 escaped the boundary of Sun's influence and became the second spacecraft to enter interstellar space after its twin counterpart Voyager 1. Since then, Voyager 2 has been beaming back information about the space beyond the Solar System.

    The recent discovery about the increasing space density has surprised everyone. This is not the first time that such an increase in density has been detected. In 2013, Voyager 1 made a similar observation, but at a different location. The new findings have not only confirmed Voyager 1's observations but have also hinted that an increased surface density might be a widespread feature of Very Local Interstellar medium (VLIM).

    The VLIM is the space outside the heliopause, where the heliopause is the Solar System's edge that the Voyagers have crossed.

    Several theories have been put forth time and again to explain this density increase. One theoretical model suggests that the increase might be due to interstellar magnetic fields becoming stronger as they bend over heliopause. Another model predicts that the interstellar wind slows down as they approach heliopause and this builds up the density.

    However, more data is needed to untangle the mystery of increased density.

    The spacecraft officially entered interstellar space in August 2012, almost 35 years after its voyage began. The discovery wasn't made official until 2013, however, when scientists had time to review the data sent back from Voyager 1.

    Voyager 1 was actually the second of the twin spacecraft to launch, but it was the first to race by Jupiter and Saturn. The images it sent back have been used in schoolbooks and newspaper outlets for a generation. Also on board was a special record, carrying voices and music from Earth out into the cosmos.

  • Voyager Journey to the Stars


    Cosmic Journeys examines the great promise of the Voyager mission and where it will lead us in our grand ambition to move out beyond our home planet. The two Voyager spacecraft are part of an ancient quest to push beyond our boundaries... to see what lies beyond the horizon. Now tens of billions of kilometers from Earth, two spacecraft are streaking out into the void. What will we learn about the Galaxy, the Universe, and ourselves from Voyager's epic Journey to the stars?

    December 19, 1972... the splashdown of the Apollo 17 crew capsule marked the end of the golden age of manned spaceflight. The Mercury.... Gemini... and Apollo programs had proven that we could send people into space... To orbit the Earth.... Fly out beyond our planet... Then land on the moon and walk among its ancient crater.

    The collective will to send people beyond our planet faded in times of economic uncertainty, war, and shifting priorities. And yet, just five years after Apollo ended, scientists launched a new vision that was just as profound and even more far-reaching.

    It didn't all go smoothly. Early computer problems threatened to doom Voyager 2. Then its radio receiver failed, forcing engineers to use a back up. Now, after more than three and a half decades of successful operations, the twin spacecraft are sending back information on their flight into interstellar space. Along the way, they have revealed a solar system rich beyond our imagining.

    The journey was made possible by a rare alignment of the planets, a configuration that occurs only once every 176 years. That enabled the craft to go from planet to planet, accelerating as they entered the gravitational field of one, then flying out to the next. The Voyagers carried a battery of scientific equipment to collect data on the unknown worlds in their path. That included a pair of vidicom cameras, and a data transfer rate slower than a dialup modem.

    Here at SpaceRip, we value the exploration of the unknown. We surpass boundaries for the sake of uncovering the mysteries of the cosmos and what they may tell us about our origin and our future. With our videos, we hope to educate our viewers on how we fit into the universe, and more so how we can do our part to better it.

    We have partnered with MagellanTV with the goal of providing our viewers with insight regarding our uncertain future on Earth and beyond. Equipped with knowledge, we hope to inspire people to enact change and pave the way for a better tomorrow.

  • Voyager 2 Is Back Online And Gathering Data Again!


    From the craft itself, to what it is doing in space, to the new information is has discovered, join me as we explore how the Voyager 2 is back online and gathering data again!

    Subscribe for more videos:

    Space is huge, and because of that, we need help exploring it, even when it's just exploring our solar system. It took us an incredible amount of time just to find and understand part of what makes our solar system special. From the 9 (not eight!) planets, to the moons of the planets, to the sun, and more. But to really venture into deep space and understand what's out there, we needed not one, but two probes known as Voyager (enter Star Trek reference here).
    Voyager 1 is a probe that humanity sent out to observe the universe at large, and it's currently well past Pluto and has shown us many things about our solar system. In 2017, it was set at around 138 AU's from our planet. AU means Astronomical Unit, which in this case means the distance from the Earth to the Sun. So 138 AU's means that it's 138 times far than the Earth is from the sun right now. That's a really big number. Over 12 billion miles to be exact. That's the farthest anything from man has traveled in space.
    One of its crowning achievements was a photograph showing a set of sunbeams, and in one of those sunbeams was earth. It was a dot. A dot in a grander scale photograph of our solar system. That's how small we are in the scale of our system when you look from the outside in, we are a dot. An epic dot, but a dot no doubt.
    As for Voyager 2, despite it launching BEFORE Voyager 1 (by 16 days), it was set on a similar mission to explore the solar system. Albeit via a different route that took it past Neptune and Uranus. The point here is that these two probes are the farthest things that humanity has sent into the solar system. They have traveled incredible distances and are still revealing things about our solar system that continue to both boggle the mind and astound us.
    Voyager 2 is now in Interstellar Space, a crowning achievement in and of itself. But that doesn't mean it's been all smooth sailing, far from it in certain ways In February 2020, it was noted by NASA that something had gone wrong with Voyager 2, and as such they had problems getting it to work properly. Given that the probe is in space that humanity hasn't touched, and will likely not touch themselves for a long time, this is to be expected. However, a few days after that announcement, they revealed to the world that they had stabilized the problems on the craft and got it back up and working.
    But what exactly caused the problems of the probe? Well, that would be a failed maneuver. Voyager 2 was supposed to do a rotation move that would shut off some of its instruments and thus conserve power. However, for whatever reason, the probe didn't do it, and because of that, the scientific instruments that were on at the time...remained on...which made it so that the probe eventually shut down prematurely.
    Not something you want to happen in the reaches of interstellar space when ANYTHING can happen in the blink of an eye.
    This failure could've been catastrophic, because you see, to ensure that the probe would have a long life in space, it was given the bare essentials in many aspects, including its power supply. Believe it or not, despite being in space for over 42 years the Voyager 2 doesn't have the biggest power supply, it actually uses radioactive fuel to produce heat, and thus power. But to conserve that power, it shuts off non-essential systems when it's not using them.
    So for the move to fail caused a serious drain in power, and likely sent NASA into quite a frenzy as they tried to make it work once again. Thankfully for them, on February 5th, 2020, they were able to connect with Voyager 2 once again, and confirm that it was up and running and able to continue its scientific mission in regards to examining and studying interstellar space.
    Voyager 2 has returned to normal operations following the anomaly on Jan. 25, 2020, NASA officials wrote in a statement. The five operating science instruments, which were turned off by the spacecraft's fault protection routine, are back on and returning normal science data.
    To give you some context as to how dramatic that is in terms of time and space. At present, it takes a signal from NASA to the Voyager 2 (or vice versa) about 17 hours. Which means that Voyager 2 is indeed one of the farthest man-made object in space right now. It's almost as far in space as Voyager 1. And that also means that if NASA asked Voyager 2 something, and it replied, it would take about a day and a half for NASA to get its answer. That makes it 122 times greater in distance from the Earth than the sun is. Or 122 AUs.

  • Elon Musks Future City


    According to Forbes Elon Musk, the CEO and founder of Tesla and SpaceX is the most innovative person in the world for the consecutive second time this year. And that is very clear of the unbelievable success he has achieved in business. Ten years ago, people considered him a reckless man with extravagant ideas. In 2008, his company Tesla collapsed during the financial crisis. Now Tesla is one of the most successful niche car companies in producing electric cars, all due to the fact that Elon Musk persevered and was determined. He has done what was thought to be impossible 10 years ago. But he has no plans of stopping soon. He has many innovative and wild plans for the future of mankind which would improve the quality of our lives.

    Business Enquiries:
    Elon Musk believes that day by day the technology is only getting better and better. Things are developing so fast that the future might be filled with Exponential tech advances that would change the world. In the future, we will have video games so realistic that it would be difficult for us to tell the difference between games and reality. From self driving tunnel networks to brain controlled computers, we’re going to look at how Elon Musk and his technology will take us forward and creating the city of the future. Elon says that we always want the future to be better than the past. A future that is exciting and one that the people would want to live in. A few decades ago a lot of technological advances seemed unimaginable but today they are our new normal, life without them is unimaginable. So let’s look at what would Elon Musk’s city of future look like. 

    So how will we get from one city to another in Elon’s future city? It’s hard to imagine being able to fly from New York City to Shanghai in 39 minutes or from Sydney to London in an hour. But this is something that Elon and SpaceX are working on. Elon compares Space Rockets to airplanes saying that if you do not reuse a plane, it would cost up to 250 million dollars to fly one way but because we can reuse them tens of thousand of times, it becomes affordable. The same is true for Space Rockets. A SpaceX rocket costs about 57 million dollars and if the rocket is reused a thousand times it nearly costs 57 thousand dollars per flight and by carrying people, we can get the price of a rocket flight down to the price of an economy flight ticket. The starship rocket is being developed to take people to mars, it can also transport people from city to city. In a 2017 interview Elon said that he is working for this to become a reality in the next 10 years and if you can carry people, you can also carry cargo which means a super fast delivery for people. Another way of getting packages fast from one part of the country to another will be by Electric semi trucks being developed by Tesla. These semi trucks require a driver but in the future we will see entirely driverless version of these and making deliveries and making the transportation cheaper. Also these trucks will be good for environment because 25% of greenhouse gases come from the trucking industry.  Though these ideas seem far fetched and Elon has planned to make them possible in the next 10 to 12 years. There is yet another way that Elon plans to develop, and that is transportation via hyper loop.  Elon Musk asks that when you think about a new transportation system, what would you want ideally? You will want something that would cost half the price to travel, would be twice as fast, cannot crash and immune to weather. To make this possible Elon is working on the idea of Hyperloop, which will take about 12 minutes to travel from Dubai to Abu Dhabi and will also be powered by solar panels. There will be Hyperloop stations inside cities, making it easier and faster to travel. There are several Hyperloop routes being planned and in the Elon’s future they will be a major subject of attraction.

  • Voyager 2 is Revealing Something Surprising about Interstellar Space


    #voyager2 #voyagermission #interstellarspace

    The Voyager 2 spacecraft, which has been in operation since 1977 and is the only spacecraft to have ever visited Uranus and Neptune, has made its way to interstellar space, where its twin spacecraft, Voyager 1, has resided since August 2012. During its travels through the outer solar system, Voyager 2 visited all four gas giant planets, and also discovered and photographed many of the planets' moons.

    The spacecraft's flyby of Neptune in 1989 set it on a course below the elliptic plane that eventually took it to interstellar space on November 5, 2018. In 1998, engineers switched off the spacecraft's nonessential instruments to conserve power. Data from at least some of the six instruments still in operation should be received until at least 2025.

  • Voyager 2 Proves Solar System is Squashed


    Voyager 1 and Voyager 2 headed on different paths out of the Solar System toward interstellar space. Traveling at different speeds and in different directions, Voyager 1 encountered the termination shock at 94 astronomical units (AU) and Voyager 2 encountered it at only 84 AU. The result, as seen in this combination of an artist's concept and a researcher's model, is a somewhat 'squashed' picture of the solar system.

    As of August 30, 2007, NASA's Voyager 2 spacecraft has followed its twin Voyager 1 into the solar system's final frontier, a vast region at the edge of our solar system where the solar wind runs up against the thin gas between the stars.

  • Life On Venus? We Joked!


    Life on Venus? We joked!
    Do you remember last September 14th? That day the scientific world was shaken by really unexpected news. It seemed that in the cloud cover surrounding the planet Venus a substance, phosphine, had been discovered, which here on Earth is produced only by processes of biological origin. If confirmed, this would have led to an astonishing conclusion: there is life on Venus!
    Microbial life, of course, but it would have been truly epoch-making news... After decades of searching for a sign of alien life on Mars, the planet most similar to the Earth in terms of environmental conditions, the miracle happens in the infernal atmosphere of Venus!
    Is it possible? If it were true, that would be proof that life can settle anywhere, even in the most hostile environments of the Solar System...
    So there was great enthusiasm... but just a month and a half later, something began to go wrong...

    Business Enquiries:
    What went wrong? Well, to understand it, it's better to go through the story very briefly first (which is already covered in our video: Life forms on Venus?).
    On 14 September last, an international team of astronomers led by astrophysicist Jane Greaves announced that they had detected traces of phosphine, a toxic gas composed of phosphorous and hydrogen (PH3), in the Venusian atmosphere, in quantities a thousand times greater than those found in the Earth's atmosphere.
    To succeed, the team used the observations of two different radio telescopes: the James Clerk Maxwell Telescope in Hawaii and the Atacama Large Millimeter / submillimeter Array in Chile, which showed a characteristic absorption of light at a specific wavelength corresponding to that of phosphine.
    On Earth, phosphine is produced almost entirely by microbes and only negligible traces come from non-biological processes; and the amount of phosphine found on Venus is much greater than what could theoretically be produced by non-biological mechanisms. Phosphine can be produced by lightning or cosmic rays hitting the upper atmosphere, but these small amounts are destroyed as quickly as they are created. In short, something on Venus is producing phosphine much faster than it can be destroyed - ten thousand to one million times faster. What can it be?
    In the article, published in the scientific journal Nature Astronomy, the authors list the different geochemical and atmospheric mechanisms potentially responsible for the presence of the molecule and discard them all one after the other, concluding in the end that phosphine is most likely produced by microorganisms that have colonized the more temperate part of Venus' atmosphere.
    The key to everything lies in that most likely... Jane Greaves is convinced of the goodness of her observations, but of course she also knows that the discovery must be confirmed by other researchers and other data before being consigned to history.
    Planet scientist Carl Sagan, who was the first to speculate about the possibility of microbial life on Venus back in the 1960s, loved to say that extraordinary claims demand extraordinary evidence. Extraordinary evidence that in this case, as the authors themselves acknowledge, does not exist at the moment.
    But one could also say that extraordinary affirmations create extraordinary expectations! And, despite the enormous caution with which Greaves presents her discovery to the world, the media immediately take over the news, fuelling the enthusiasm of millions of people fascinated by the problem of life in the universe.

  • ????Depois de sete meses, NASA volta a entrar em contato com a sonda Voyager 2.????


    Depois de sete meses, NASA volta a entrar em contato com a sonda Voyager 2.

    Os operadores têm sido incapazes de enviar transmissões de rádio para a sonda espacial Voyager 2 desde meados de março, mas um teste recente de hardware recém-instalado deu um bom sinal de que as atualizações da Deep Space Network da NASA estão ocorrendo conforme planejado.

    A NASA enviou um comando para a Voyager 2 em 29 de outubro, algo que ela não tinha conseguido fazer há sete meses, de acordo com um comunicado da agência. Os operadores da missão fizeram isso usando a Deep Space Station 43 (DDS43) — a única antena de rádio capaz de se comunicar com a espaçonave. Lançada em 1977, a Voyager 2 está atualmente a 18.792 milhões de quilômetros da Terra. Ela e sua parceira Voyager 1 são os objetos de fabricação humana que foram mais longe no universo.

    A antena de rádio está offline devido a reparos e atualizações muito necessários. A reconexão bem-sucedida não deveria acontecer até daqui a três meses, mas o teste inicial do hardware recém-instalado, no qual a Voyager 2 retornou um sinal de “alô” conforme ordenado, é uma boa notícia, pois o equipamento deve voltar a ficar online só em fevereiro de 2021.

    A NASA não conseguiu falar com a Voyager 2 durante o intervalo de sete meses, mas a sonda estava transmitindo atualizações de saúde e informações científicas importantes. A sonda está atualmente viajando pela heliosfera a 55.160 km/h, onde está explorando esta região expansiva semelhante a uma bolha do sistema solar externo.

    A Deep Space Network é um conjunto de antenas de rádio localizadas ao redor do mundo e seu objetivo principal é se comunicar com espaçonaves que estão além da Lua. Localizado em Canberra, Austrália, o DDS43 é uma engrenagem importante neste sistema, mas, aos 48 anos, precisava urgentemente de uma atualização. A antena de rádio de 34 metros de largura já passou por melhorias antes, mas, nos últimos 30 anos, ela nunca tinha ficado tanto tempo desligada.

    “A antena DSS43 é um sistema altamente especializado; existem apenas duas outras antenas semelhantes no mundo, então deixar a antena desligada por um ano não é uma situação ideal para a Voyager ou para muitas outras missões da NASA”, disse Philip Baldwin, gerente de operações do programa de Comunicações e Navegação Espacial (SCaN) da NASA. “A agência tomou a decisão de conduzir essas atualizações para garantir que a antena possa continuar a ser usada para missões atuais e futuras. Para uma antena de quase 50 anos, é melhor ser proativo do que reativo com manutenção crítica.”

    Esses reparos e atualizações serão benéficos para outras missões, incluindo a Mars Perseverance (atualmente a caminho de Marte) e as próximas missões Artemis para a superfície lunar, para não mencionar futuras viagens a Marte envolvendo humanos.

    Pode parecer surpreendente que somente uma das antenas parabólicas na Terra possa se comunicar com a Voyager 2, mas há um bom motivo para isso. Para que a sonda sobrevoasse a lua Tritão, de Netuno, em 1989, os operadores da missão tiveram que enviar a sonda sobre o polo norte do gigante de gelo. Esta trajetória exigia que a sonda viajasse em uma direção sul em relação ao plano orbital reto, e desde então ela tem se movido nesta direção.

    A consequência dessa manobra é que a Voyager 2 agora viajou tão ao sul do plano planetário que não pode ser alcançada por antenas de rádio no hemisfério norte da Terra. Sua irmã Voyager 1 ainda pode ser alcançada por um par de antenas no hemisfério norte, pois a sonda tomou um caminho diferente, passando por Saturno.

  • How Voyager 1 and 2 spacecrafts traversed our solar system.


    Official NASA Website about NASA JPL Voyager Interstellar mission. Check it out!

    Have you ever wondered how is it that two small space crafts named Voyagers that #NASA launched in to space back in 1977 were able to traverse all across our solar system to see all those giant planets up close with unprecedented precision and control and return back amazing revelation about those unknown worlds? Well, hit the play button and let's go and ride along with them.

    Voyager missions were launched in 1977 for doing an initial reconnaissance mission of our planets in our solar system. Voyager 1 spacecraft went on to flyby giant planets like Jupiter and Saturn and then it went on to explore the unknown, in to the interstellar space. As of 2012, Voyager 1 is in the interstellar space. Voyager 2 Spacecraft went on to visit Jupiter and Saturn but in addition to that, it also went past Uranus and Neptune to give us the very first close up views of those unknown worlds. In-fact even now, those images returned by Voyager 2 are the only images that we have of those planets. Voyager 2 is also headed for interstellar space but it is very near to the region where our sun's presence ends and the interstellar medium ie. space between the stars, begins.
    If you want to know more about the timeline of Voyager mission, check out this page:

    Voyagers are continuing their mission in to realms that are outside our reach, even after 40 years of tireless service which shows how tough those two space crafts are. They are currently in a medium which is not the same as that from which they were made out of. They will continue to operate at-least for another decade when their power sources will dwindle leading to shutting down of instruments one by one until they can't be operated anymore. Afterwards, the voyagers will wander around the Milky-way galaxy like eternal wanderers, carrying some of the messages that we have put on them on a gold plated copper disk for any civilization that might recover them in the future. It shows the amount of human hope which those two spacecraft carry with them.

    Please share the story of these two amazing little spacecrafts if you think they are worthy of a few clicks of your mouse.

    did you pass the labyrinth
    of stones that tides have hewn?
    and did you pierce the crystaline crown
    of gems the sun has strewn?

  • 6 Galaxies Trapped In The Web Of An Ancient Supermassive Black Hole


    A very giant web of a giant supermassive black hole that has been feeding on the gas of six galaxies has been observed by astronomers using ESO’s Very large telescope. We believe these galaxies to have been trapped in the spider like web of this giant super-massive black hole. The finding helps to better understand how supermassive black holes, one of which exists at the centre of our Milky Way, formed and grew to their enormous sizes so quickly. It also supports the theory that black holes can grow rapidly within large, web-like structures which contain plenty of gas to fuel them, according to the astronomers.So how is it possible? IS it because of Dark matter! Or any other phenomenon!! Let’s find out.

    Business Enquiries:
    Black holes are some of the strangest and most fascinating objects in outer space. They’re extremely dense, with such strong gravitational attraction that even light cannot escape their grasp if it comes near enough. Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term “black hole” was coined many years later in 1967 by American astronomer John Wheeler. After decades of black holes being known only as theoretical objects, the first physical black hole ever discovered was spotted in 1971. Since then, black holes have been a centre of attraction and research for many astronomers. A black hole is formed when the centre of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Have you ever wondered if light can’t escape a black hole, how can we see black holes? Well, we don’t see a black hole, we observe the presence of a black hole by its effect on its surrounding. They are very hard to detect in our own galaxy. Then, In 2019 the Event Horizon Telescope (EHT) collaboration released the first image ever recorded of a black hole. The EHT saw the black hole in the centre of galaxy M87 while the telescope was examining the event horizon, or the area past which nothing can escape from a black hole. The image maps the sudden loss of photons (particles of light). It also opens up a whole new area of research in black holes, now that astronomers know what a black hole looks like. Black holes are strange and hard to study. There are a good deal of strange once that exist in our universe and have been observed by the scientists. We already have made a video on these strangest black holes of the universe and also about the first photograph of a black hole. We will leave their link in the description below. 

    Supermassive black holes are one of the most challenging astronomical objects in the universe. Not much is known about them except that they are very huge and are present at the centre of every galaxy. Supermassive black holes are extreme systems, and, to date, we have had no good explanation for their existence. Scientist know little about them. Their formation and especially their formation in the early universe is a very intriguing question that scientists look to answer. “Our work has placed an important piece in the largely incomplete puzzle that is the formation and growth of such extreme, yet relatively abundant, objects so quickly after the Big Bang,” said Roberto Gilli, and astronomer at INAF in Bologna. It is thought the first black holes, believed to have formed from the collapse of the first stars, must have grown very fast to reach a billion solar masses within the first 900 million years of the Universe’s life.

    In this video, we discuss about the methods through which we get the images or photographs of the planets by the spacecrafts.
    we may wonder that how it actually happens, because of the unimaginable distance from earth to other planets.
    for example the voyager spacecrafts 1&2 have given us so many images of Jupiter, saturn and their moons and the ice giants' as well.
    and the new horizon spacecraft has also given wonderful pictures of pluto... so, this is why the question arose how was this possible,

    NASA measurements for planetary distances (averaged due to elliptical orbit):


    August 20, 2017 marks the fortieth anniversary of the launch of Voyager 2. Along with Voyager 1, NASA sent the twin spacecraft to collect data about giant planets of our outer solar system. Voyager 2 was the first spacecraft to visit Uranus and Neptune, as well as discovering many new moons orbiting both Jupiter and Saturn. In addition to collecting data, Voyager 2 was sent with a copy of “The Golden Record”: a disk containing 116 images and various audio recordings that depict human life. Should Voyager 2 ever be encountered by an extraterrestrial, the record will be a means of understanding planet Earth. Besides the collection of data and the mysteries of alien life, perhaps the most wondrous aspect of Voyager 2's mission is the distance it has traveled: nearly 11 billion miles as of late 2017. It is the second-farthest human-made object from earth (the farthest is Voyager 1) and it is currently on a one-way journey into the unknown depths of interstellar space. Unable to grasp the enormity of this distance, we made a video to try and visualize what that actually looks like.

    NASA Contacts Voyager 2 – 11 6 Billion Miles From Earth – Using Upgraded Deep Space Station :
    NASA Contacts Voyager 2 – 11.6 Billion Miles From Earth – Using Upgraded Deep Space Station

    The only radio antenna that can command the 43-year-old spacecraft has been offline since March as it gets new hardware, but work is on track to wrap up in February.

    On October 29, 2020, mission operators sent a series of commands to NASA’s Voyager 2 spacecraft for the first time since mid-March. The spacecraft has been flying solo while the 70-meter-wide (230-foot-wide) radio antenna used to talk to it has been offline for repairs and upgrades. Voyager 2 returned a signal confirming it had received the “call” and executed the commands without issue.

    The call to Voyager 2 was a test of new hardware recently installed on Deep Space Station 43, the only dish in the world that can send commands to Voyager 2. Located in Canberra, Australia, it is part of NASA’s Deep Space Network (DSN), a collection of radio antennas around the world used primarily to communicate with spacecraft operating beyond the Moon. Since the dish went offline, mission operators have been able to receive health updates and science data from Voyager 2, but they haven’t been able to send commands to the far-flung probe, which has traveled billions of miles from Earth since its 1977 launch.

    Among the upgrades to DSS43, as the dish is known, are two new radio transmitters. One of them, which is used to talk with Voyager 2, hasn’t been replaced in over 47 years. Engineers have also upgraded heating and cooling equipment, power supply equipment, and other electronics needed to run the new transmitters.

    The successful call to Voyager 2 is just one indication that the dish will be back online in February 2021.

    “What makes this task unique is that we’re doing work at all levels of the antenna, from the pedestal at ground level all the way up to the feedcones at the center of the dish that extend above the rim,” said Brad Arnold, the DSN project manager at NASA’s Jet Propulsion Lab in Southern California. “This test communication with Voyager 2 definitely tells us that things are on track with the work we’re doing.”

    Worldwide Network

    The Deep Space Network consists of radio antenna facilities spaced equally around the globe in Canberra; Goldstone, California; and Madrid, Spain. The positioning of the three facilities ensures that almost any spacecraft with a line of sight to Earth can communicate with at least one of the facilities at any time.

    Voyager 2 is the rare exception. In order to make a close flyby of Neptune’s moon Triton in 1989, the probe flew over the planet’s north pole. That trajectory deflected it southward relative to the plane of the planets, and it has been heading in that direction ever since. Now more than 11.6 billion miles (18.8 billion kilometers) from Earth, the spacecraft is so far south that it doesn’t have a line of sight with radio antennas in the Northern Hemisphere.

    DSS43 is the only dish in the Southern Hemisphere that has a transmitter powerful enough and that broadcasts the right frequency to send commands to the distant spacecraft. Voyager 2’s faster-moving twin, Voyager 1, took a different path past Saturn and can communicate via antennas at the two DSN facilities in the Northern Hemisphere. The antennas must uplink commands to both Voyagers in a radio frequency range called S-band, and the antennas downlink data from the spacecraft in a range called X-band.

    While mission operators haven’t been able to command Voyager 2 since DSS43 went offline, the three 34-meter-wide (111-foot-wide) radio antennas at the Canberra facility can be used together to capture the signals that Voyager 2 sends to Earth. The probe is sending back science data from interstellar space, or the region outside our Sun’s heliosphere – the protective bubble of particles and magnetic fields created by the Sun that surrounds the planets and the Kuiper Belt (the collection of small, icy bodies beyond Neptune’s orbit).

    DSS43 began operating in 1972 (five years before the launch of Voyager 2 and Voyager 1) and was only 64 meters (210 feet) wide at the time. It was expanded to 70 meters (230 feet) in 1987 and has received a variety of upgrades and repairs since then. But the engineers overseeing the current work say this is one of the most significant makeovers the dish has received and the longest it’s been offline in over 30 years.
