  • Betelgeuse Explained

    28:39

    At the beginning of 2020, the world held its collective breath as a nearby behemoth star, called Betelgeuse, start to dramatically fade. Could this mean the star is about to go supernova? With the recent flutter of news activity settling down, we are now finally starting to understand what might have really happened. Today, we take a deep dive into what makes massive stars like this tick, and then get into how we might have now finally come up with answers to this bizarre event.

    An educational video written and presented by Prof. David Kipping.

  • Mysterious Dimming of Betelgeuse Explained

    3:10

    The unexpected and significant dimming periods of Betelgeuse in late 2019 and early 2020 has puzzled astronomers around the world. Some believed that it signaled the star's upcoming explosion. But then the dimming abruptly stopped. Thanks to observations by NASA's Hubble telescope we now know that the dimming periods were most likely caused by the ejection and cooling of dense hot gases and that the star may be going through another dimming period about a year earlier than expected.

  • Full Space Documentary - Mystery of the Red Supergiant Star Betelgeuse

    46:15

    Betelgeuse, also called Alpha Orionis, second brightest star in the constellation Orion, marking the eastern shoulder of the hunter. Its name is derived from the Arabic word bat al-jawzāʾ, which means “the giant’s shoulder.” Betelgeuse has a variable apparent magnitude of about 0.6 and is one of the most luminous stars in the night sky. It is easily discernible to even the casual observer, not only because of its brightness and position in the brilliant Orion but also because of its deep reddish colour. The star is approximately 640 light-years from Earth.

  • Dimming of Betelgeuse explained.

    2:04

    On December 2019 astronomers predicted that the star Betelgeuse may explode soon.
    This was based on its unusual dimming.
    But nothing happened and the star returned to its normal brightness. What was behind its dimming? We are investigating the curious case of Betelgeuse through Physics Oversimplified.

  • High Mass Stars: Crash Course Astronomy #31

    12:17

    Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The shock wave, together with a huge swarm of neutrinos, blast through the star’s outer layers, causing it to explode. The resulting supernova creates even more heavy elements, scattering them through space. Also, happily, we’re in no danger from a nearby supernova.

  • Betelgeuse supernova from earth Explained |striving amateur |Astronomy

    3:01

    Betelgeuse supernova from earth is not going to happen ! #period
    Betelgeuse is a star that was supposedly dimming and the astronomy community was wildly divided about the whole dimming ,attributing it to be a precursor to a supernova.

    A group of researchers analysed the UV light from the star using the Hubble space telescope and came to a conclusion that it was actually caused by a dust cloud that erupted from the star itself that triggered this dimming.

    Betelgeuse is one of the most luminous stars in the night sky. It is one of the closest supernova candidate, which is situated 700 light-years away from Earth.

    This red giant star is younger than our sun, but the star has already reached the final stages of its life. It would take billions of years for our sun to reach this stage.

    High mass stars such as Betelgeuse burn their fuel extremely quickly, as a result they exist for only a few million years, stars such as our sun exist for billions of years. Betelgeuse is easily visible in the night sky, as it is the tenth brightest star in the night sky and is more than 15 times the mass of the Sun.

    when will Betelgeuse go supernova?
    When Betelgeuse will die, it will create a stunning supernova that will be visible on Earth, even in broad daylight.

    This is because when a massive star runs out of material in its core, the star will collapse under its own gravity and turn into a supernova. Researchers have estimated that this will likely happen to Betelgeuse within the next 100,000 years, which is relatively soon in astronomical terms. This explosion will create a burst capable of briefly outshining an entire galaxy.

    This would be the first naked-eye supernova in our galaxy since 1,604. It will become the most-witnessed astronomical event in human history.

    Characteristics of Betelgeuse
    Betelgeuse is a red giant star with a low surface temperature. The low temperature means that the star will appear orangish red in color. The surface of Betelgeuse is relatively colder than the Sun since its core is no longer capable of sustaining hydrogen fusion. The temperature of its surface is just 6000 degrees Fahrenheit, for comparison our sun's surface temperature is 10000 degrees Fahrenheit.

    The diameter of Betelgeuse is about 700 Million miles, which is about 1200 times the size of the Sun. It is is one of the largest known stars in the milky way.
    Betelgeuse is so huge that if it was at the center of our solar system, its surface would lie beyond the asteroid belt and it would swallow Mercury, Venus, Earth, Mars and probably Jupiter.

    Betelgeuse is only 8 million years old, astronomers suspect that it would live for another 100,000 years after which its core would collapse into a super dense neutron star. This supernova explosion might appear as bright as the full moon as seen from Earth.

  • What is Causing the Mysterious Dimming of Betelgeuse? with Dr. Andrea Dupree

    33:56

    Why is Betelgeuse dimming?

    The supergiant is going to end its life as a supernova. Is the sudden dimming a warning sign? Betelgeuse is a variable red super giant star located in the Orion constellation. Most estimations have it going supernova within the next 100,000 years, but could it be sooner? Dr. Andrea Dupree, associate director of the Center for Astrophysics at the Harvard & Smithsonian institute, joins John Michael Godier to discuss recent observations of Betelgeuse by Hubble.

    Hubble Finds That Betelgeuse's Mysterious Dimming Is Due to a Traumatic Outburst:

  • Will Betelgeuse Explode? This Is What Scientists Know So Far

    4:48

    The massive red supergiant Betelgeuse has been losing its sparkle, leading many scientists to wonder: is one of the sky’s brightest stars headed toward its demise by way of a supernova explosion?

    Betelgeuse, often pronounced like Tim Burton’s “Beetlejuice,” is dimming at an unprecedented rate. While the star is known for its erratic behavior, shrinking then expanding and dimming then flaring on a semi-regular basis, Betelgeuse’s recent behavior has been stranger than normal.

    According to recent reports, Betelgeuse has cooled by roughly 100 Kelvin since September 2019 and is now hovering around an apparent magnitude of over 1.6, a significant drop from its average range of 0.4 to 1.2 magnitudes of brightness.

    In fact, the supergiant star has now been demoted to roughly the 21st brightest star in the night sky, which is the faintest Betelgeuse has been in at least a century.

    And that’s not all—other strange things are also happening to the star. For one, it’s shedding quite a lot of mass, but instead of generating lots of heat like scientists would assume, it’s staying cool.

    Betelgeuse is also defying expectations with its super-speed rotation, which has been observed to be spinning around 150 times faster than would be expected for a star this big. Not to mention, in the early part of 2020, astronomers observed a “burst” of gravitational waves coming from the area near the star.

    So what is going on with Betelgeuse and is it about to go supernova? Find out in this Elements.

    The Biggest Celestial Event of the Year Could Happen Tomorrow

    Or … you might see the regular old sky. Supernovas are nearly impossible to predict. But astronomers have recently started discussing the rare possibility with a bit more enthusiasm than usual, thanks to some odd behavior elsewhere in the Milky Way. If the supernova did show up tomorrow, it would be the celestial event of the year, perhaps even the century, leaving a cosmic imprint in the sky for all to see.

    Waiting for Betelgeuse to Explode

    Betelgeuse is a young star near the end of its life. It formed about 8 million years ago, when the far distant ancestors of humans were just beginning to split away from the great apes.

    Astronomers Will Be Ready To Study Future Supernovas In Action

    Supernovas are rare; less than 1 percent of all stars are big enough for such a fiery death. (Our relatively small sun will fade away gracefully as a white dwarf.) In a galaxy the size of our Milky Way, though, astronomers estimate roughly one or two supernovas should still light up per century.

  • Astronomers Think They Know Why Betelgeuse Got Dimmer

    10:00

    Betelgeuse stopped dimming in the middle of February, and now some of the first papers studying the anomalous brightness variation are starting to appear. It doesn't look like the star got cooler, there wasn't a giant starspot that lowered the output, and there wasn't a cloud of gas in the way. Instead it seems like dust is likely to be the culprit.

    We have some great images by the star using the SPHERE instrument at ESO, taken by Miguel Montargès showing a darker area on the star, this shows that the dimming wasn't a global event.
    There's another image from December showing the dust environment further out from the star taken by Pierre Kervell using the VISIR instrument.

    However the most interesting evidence is comes from a team who did spectroscopy, trying to figure out if the star had god cooler.
    I want to cover this paper by Emily M. Levesque & Philip Massey
    Betelgeuse Just Isn't That Cool: Effective Temperature Alone Cannot Explain the Recent Dimming of Betelgeuse
    Because it offers a good explanation of how astronomers have to go about finding the temperature of stars and because Emily wrote an excellent Twitter thread explaining their process

  • What If The Star Betelgeuse Explodes | The Supernova of Betelgeuse | The Secrets of the Universe

    4:43

    Betelgeuse is a red supergiant star in the constellation of Orion. At its deathbed, Betelgeuse can go supernova any moment. Recent dimming of Betelgeuse has made scientists speculate if its end is near. When Betelgeuse will explode, its brightness will be equivalent to that of the full moon. The supernova of Betelgeuse will even be visible with the naked eye. It will also create of burst of neutrinos before it explodes.

    Whenever it will explode, the supernova of Betelgeuse is the most awaited astronomical event of all. Hope we are lucky enough to witness this rare event.

    Betelgeuse probably isn't about to explode, but that's no reason not to get to know it.

  • Did dust darken Betelgeuse, and is it dimming again?

    10:06

    Did dust darken Betelgeuse, and is it dimming again? New results from the Hubble Space Telescope suggest that Betelgeuse ejected a massive cloud of dense dust that obscured the red supergiant star, and caused the Great Dimming of Betelgeuse in 2019 and early 2020. However, there are still other questions about what caused Betelgeuse to dim that remain unanswered. To make matters even more confusing, astronomers observed Betelgeuse this summer using the STEREO solar observatory. They found that Betelgeuse is starting to dim again!

  • Betelgeuse live observation - speculations of Super Nova.

    7:48

    I am sorry, the star Betelgeuse has another million years to go, way beyond our average human civilization on Earth, say about a 1000 years before God hits the reset button!?! Interestingly, the buzz around the world is beetle juice, beetle juice, beetle juice - kids be loving bug juices. If Betelgeuse were to Super Nova, we'd be in trouble, that by God's palm smacking the reset button here on Earth.

    I made this live video of Betelgeuse per viewer request. *** Stay Warm bud (y)
    Imaging Betelgeuse, the focus was never changed on the Canon EF 400mm telephoto lens fronted by the 77mm Hoya Infrared filter using a mono CMOS camera.

    Betelgeuse is usually the eleventh-brightest star in the night sky and, after Rigel, the second-brightest in the constellation of Orion. It is a distinctly reddish semiregular variable star whose apparent magnitude, varying between +0.0 and +1.3, has the widest range displayed by any first-magnitude star.

  • Why is Betelgeuse Dimming? With Dr. Edward Guinan

    40:56

    Why is Betelgeuse dimming? Is Betelgeuse about to explode? Betelgeuse is a variable red super giant star located in the Orion constellation. Most estimations have it going supernova within the next 100,000 years, but could it be sooner?

    Dr. Edward Guinan has been studying Betelgeuse and other variable stars from Villanova for over 40 years. He joins John Michael Godier to discuss his recent updates on the fainting and dimming of Betelgeuse.

    Betelgeuse is still fading and a new image of Betelgeuse shows it has a new, lumpy shape! The image was made in December 2019 at ESO's Very Large Telescope. While it's not likely to go supernova anytime soon, the new image shows Betelgeuse as we've never seen it before. Meanwhile, it's still fading though it seems to have leveled off. Astronomers are still trying to figure out what's happening to Betelgeuse.

  • Betelgeuse Gets Darker, But Its Probably Not Going To Explode

    11:20

    Betelgeuse is the reddest star visible in the night sky, a red supergiant a few hundred light years from Earth it's likely to become a supernova in the next hundred thousand years or so. Recently it faded and became half as luminous as usual, and some more clickbaity publications suggested a supernova might be imminent.
    And that would be amazing.
    But don't place any bets on it, all the science suggests it's still young enough that it's burning helium, so we have plenty of time to watch it being Orion's shoulder.

  • Betelgeuse Is Continuing To Dim: What s Really Happening?

    13:02

    From what it could mean, to the various reasons for this phenomenon happening at all, join me as we explore betelgeuse continuing to DIM! What' s really happening?
    Out in space in the Orion constellation, there is a very bright star in our night sky known Betelgeuse. To put it most simply, it is a red supergiant, and one that dwarfs many others stars in the sky. Such as the big star known as Rigel which it outsizes in a rather significant way. Mainly because this star is 1.3 BILLION kilometers long. That's basically three times the size of Rigel, which for the record is 97 million kilometers long. So yeah, definitely not a small star.
    For a comparison, if some kind of cosmic event somehow dropped this massive star into our own solar system and replaced our own sun with it (which obviously won't happen but why ruin the moment here?), the mass of Betelgeuse would basically destroy everything from the point of the sun all the way until Jupiter more than likely. So you should be glad this isn't a thing that likely will happen...hopefully.
    Betelgeuse is also the 10th brightest star in the sky overall, and it’s the 7th brightest star visible from most of the U.S., Canada, Europe and the majority of the Northern Hemisphere.
    What's that? How big is Betelgeuse compared to the Earth? I'm glad you asked! The Earth is about 40,000 kilometers long in circumference. Which means that this supergiant is 32,500 times bigger than us. That's a lot. Like really, that's a lot of mass for a single star.
    So yeah, that's Betelgeuse on a very basic level. But there is more going on here with this star than you realize. Including the fact that one day this star is supposed to go Supernova, and when that happens, it'll be a big deal in space for reasons we can talk about another time.
    But what's getting a lot of people's attention right NOW is that Betelguese is dimming. Likely in the literal sense, the star is dimming in a way that is clearly intentional/forced, and many astronomers are trying to figure out what's going on with it.
    Wait a minute, you say, didn't you just note that the star is going to go supernova one day? Couldn't this be a lead-up to that event happening?
    A good question, and most times, we would say yes, as this would be an indication that the star was in the last phases of its current life and could/should go supernova at any moment. But, the problem is that based on projections of the star itself in terms of its life, it's not SUPPOSED to go Supernova for tens of thousands of years yet. Which means that this dimming is an atypical event, and one that scientists want to figure out.
    What's more, in a more recent report about the dimming itself, Villanova University astronomers Edward Guinan and Richard Wasatonic noted that while the dimming is still going on, it's happening at a much slower rate than before. Which just makes the whole situation even more odd.
    Now I'm sure you're wondering just how dim the star is actually getting, and that's a good question as well. I could bore you with talk about magnitudes or brightness, but let's just get to the heart of the matter. Over the course of the last few months, Betelgeuse has basically lost half of its usual brightness. And for a star to go from its normal shine to about half in a few months is very unprecedented in a star that isn't about to die.
    Also, to be clear, astronomers have been watching Betelgeuse for a very long time, in fact, they've been keeping their eyes on this star for over 180 years! And at no point in time since they've been watching it has the brightness ever gone that low. It's at record lows even, and when you plot it all out on a chart, you see just how weird this rapid dimming is, and it's got a lot of people in the science field scratching their heads.
    “The unusual behavior of Betelgeuse should be closely watched.” noted one scientist watching the situation.
    Another thing to note is that as the star starts to dim, its temperature drops as well. Since September 2019, the temperature of Betelgeuse has lowered by 100 Kelvin. If that continues, it could affect the star in a way that we're not expecting.
    Of course, it's entirely possible that this IS the path to it detonating itself and becoming a supernova. We just don't think this is the case.
    The life of stars is a very curious thing. As they burn very, VERY brightly in the sky, and that affects a lot of things around them. Take Earth for example. If our star burned less brightly, and thus less hot, our planet wouldn't be in very good shape. In fact, our star is quite literally perfect in regards to how far it is from Earth, the light and heat it emits, and even how much radiation it pumps out into space itself. But that last bit is another topic entirely. To burn like it does, it has a very particular balance of energy within itself. This balance is between the gasses it creates, and the gasses it burns.

  • Betelgeuse Shrinks and Dims REVEALING more clues to stars ELECTRICAL NATURE!

    11:20

    Over the past few year Betelgeuse has shrunk considerable and now in the last few months it has started to dim. Many have claimed the star is about to go supernova. By examining all the evidence we can reveal more clues about how these types of electrical stars are formed and understand how their position and velocity withing a Birkeland current may play a critical role in what we are seeing happening at the moment.

  • BETELGEUSES MYSTERIOUS DIMMING IS DUE TO A MAJOR OUTBURST

    3:27

    The aging, bright-red supergiant star Betelgeuse has captivated sky watchers since antiquity. The ancient astronomer Ptolemy was one of the first to note the monster star's red color. It is one of the brightest stars in the night sky and appears even more luminous because it is so close to Earth, only 725 light-years away.

    But the star also periodically changes in brightness, which was first noted in the 1830s by British astronomer John Herschel. Astronomers now know that the star expands and contracts, brightening and dimming, on a 420-day cycle.

    However, in October 2019, the star dimmed dramatically and continued to become even fainter. By mid-February 2020, the monster star had lost more than two-thirds of its brilliance.

    This sudden dimming has mystified astronomers, who scrambled to develop several theories for the abrupt change. Ultraviolet observations by the Hubble Space Telescope suggest that the unexpected dimming was probably caused by an immense amount of superhot material ejected into space. The material cooled and formed a dust cloud that blocked the starlight coming from about a quarter of Betelgeuse's surface.

    Hubble captured signs of dense, heated material moving through the star's atmosphere in September, October, and November 2019. Then, in December, several ground-based telescopes observed the star decreasing in brightness in its southern hemisphere.

    The giant star is destined to end its life in a supernova blast. Some astronomers think the sudden dimming may be a pre-supernova event. Betelgeuse resides in Orion, one of the most recognizable constellations in the sky. The mammoth star marks the right shoulder of the hunter.

    If Betelgeuse was at the center of our Solar System its surface would lie beyond the orbit of Jupiter.

  • Images of Betelgeuses dimming surface reveal its changing shape

    17

    This video takes the viewer from the surroundings of Betelgeuse, recently observed with the VISIR instrument on ESO’s Very Large Telescope (VLT), to its surface, which has been imaged by SPHERE on the VLT. The VISIR image shows the infrared light being emitted by the dust surrounding Betelgeuse in December 2019. The SPHERE image shows Betelgeuse’s visible surface, which has a size close to the orbit of Jupiter, in the same month. (ESO/P. Kervella/M. Montargès et al., Acknowledgement: Eric Pantin)
