  • Analyzing Video Footage Of Collapse of Massive Arecibo Telescope

    12:57

    The collapse was on Tuesday morning, but yesterday the NSF made video of the catastrophic collapse available, and so many viewers asked I continue my long tradition of 'coping by analyzing failure' and document what I see in this footage. It's hard to watch because this magnificent structure has always been part of the world of astronomy for me.

    For those that feel moved into action a starting point may well be this petition ask the White House to consider rebuilding the facility.


    Juan R Costa's images of the structure after collapse are available on the NotiCel site, they're the best images of this:

  • Footage of Arecibo observatory collapse analysed in detail

    11:27

    Arecibo telescope Collapsed on the 1 of December 2020, and footage of the collapse was released by the NSF allowing us to break down these events.
    In this video, the Arecibo observatory collapse was analysed, showing that this event was not a single failure but a series of actions that lead up to the final catastrophic collapse.

    This video analyses the collapse in detail break down each event.

    #Arecibo_Observatory was one of the most iconic scientific instruments in the world and was the first to detect gravitational waves by observing binary pulsars. The Arecibo Telescope was also the largest radar telescope in the world by around 20 times, this will be a big loss to the scientific community.

    it is not often that we are able to observe such a catastrophic collapse so close, this gives us a unique insight into the event that led up to the demise of the Arecibo observatory.

  • Shocking Footage of Arecibo Telescope Collapse | A Tribute to Arecibo

    3:44

    After being in operation for 57 years, the Arecibo observatory has finally met its demise. On December 1, at 8 AM local time, the 900-ton instrument platform suspended above the collecting dish collapsed as the suspending cables weakened over time. The collapse occurred 2 weeks after the National Science Foundation decided to dismantle the telescope due to 2 cable failures earlier this year.

    In its 57 years of operation, the observatory endured many hurricanes, humidity, and earthquakes. These factors caused a support cable to breakdown, causing a huge setback in the telescope’s operations. As engineers came out with a plan to stabilize the structure, another cable broke down on November 6th, causing massive damage to the collecting dish and the platform suspended above it. Following 2 cable breakdowns within a year, the National Science Foundation (NSF) declared the structure too weak dangerous to be repaired, and hence it was to be dismantled.

    But the telescope couldn’t survive until the scheduled dismantlement. Just within 2 weeks after NSF announced its plan, the rest of the cables broke down because of the excessive load they were bearing due to the collapse of 2 cables earlier.

    Being one of the oldest telescopes in the world, Arecibo was an asset to science. Here are some of the most contributions that the telescope made in its nearly six decades of operation.

    In 1964, a team of researchers used the telescope to determine the correct rotational period of Mercury. They found that Mercury spins on its axis once every 59 days, and not 88 days as previously thought.

    In 1968, Arecibo was used to determine the periodicity of the crab pulsar. This provided the first solid evidence for the existence of neutron stars.

    In 1974, researchers using the Arecibo telescope discovered the first binary pulsar. This discovery was awarded the 1982 Nobel Prize in Physics.

    In 1982, the first-millisecond pulsar PSR B1937+21 was also discovered using this telescope. Spinning 642 times per second, it was the fastest spinning pulsar until the discovery of PSR J1748-2446ad in 2006.

    In 1989, the observatory directly imaged an asteroid for the first time in history: 4769 Castalia.
    In 1993, pulsar PSR B1257+12 by Polish Astronomer Aleksander Wolszczan. It later led him to the discovery of three planets orbiting the pulsar. This was the first time an exoplanet was found.
    In 2008, detection of prebiotic molecules methenamine and hydrogen cyanide were reported from the observatory’s radio spectroscopy measurements of the distant starburst galaxy Arp 220.

    This news has not only saddened the scientists who have worked at the Arecibo observatory, but even the residents of Puerto Rico are also shocked. The telescope was a major tourist attraction, driving over 90,000 tourists every year. No doubt, it’s an end of an era!

  • Watch the Arecibo Observatorys catastrophic collapse!

    1:58

    The National Science Foundation has released remarkable footage of the Arecibo Observatory's 900-ton platform falling into the 1,000-foot wide (305 meters) dish below. A drone happened to be performing an up-close investigation of the cables that hold the platform above the dish as they snapped.

    Videos released Thursday by NSF show both the drone footage and the view from a camera in the visitor center that shows the platform falling into the dish just above the jungle floor in Puerto Rico. Two massive chunks of the cement towers that the cables were attached to can also be seen falling.

    Two of the cables had previously broken, one in August and another in November, destabilizing the dish.

  • What We Lost When the Arecibo Observatory Collapsed

    4:43

    The Arecibo telescope, an icon in radio astronomy, has collapsed. Here's the legacy it leaves behind.

    The destruction of this iconic observatory was due to multiple cable malfunctions. The National Science Foundation hasn’t given any further details about the fall, but we do know that at the beginning of November 2020 they’d actually been discussing plans to safely decommission the observatory by gently lowering the central platform. But unfortunately, nature had other plans. Luckily, no one was harmed in the collapse of the observatory, but sadly this ends an era of space exploration.

    The initial idea for Arecibo actually started in the 1950s by Professor William Gordon from Cornell University. Gordon had the desire to study the ionosphere, which is the layer of our Earth’s atmosphere that can reflect radio waves. The funding for this revolutionary project came from the Defense Advanced Research Projects Agency or DARPA in 1959, when Cornell University signed a contract to conduct development studies centered around large-scale radar probes. Four years later in 1963, construction was completed in the limestone hills of Arecibo, Puerto Rico.

    The completed project featured a 817-metric-ton equipment platform, which was suspended over 152 meters above its massive 305 meter spherical reflector. Making it the world’s largest single radio telescope. Well, until 2016 when China developed its own single radio telescope called the Five-Hundred-meter Aperture Spherical Radio Telescope or FAST.

    Arecibo Observatory Telescope Collapses, Ending Era Of World-Class Research

    Arecibo's 900-ton equipment platform, suspended some 500 feet above the dish, fell overnight after the last of its healthy support cables failed to keep it in place.

    Arecibo telescope collapses, ending 57-year run

    'I feel sick in my stomach,' Lugo says, fighting back tears. '“Truthfully, it was a lot of hard work by a lot of people trying to restore this facility. It’s disappointing we weren’t successful. It’s really a hard morning.'

    Why losing Arecibo is a big deal for astronomy

    Arecibo’s observing days may be over, but that doesn’t mean data from the telescope won’t make any more contributions to science, Schmelz says. Some of radio astronomy’s most exciting discoveries have emerged from the reanalysis of old telescope data.

  • Arecibo Radio Telescope Collapses!

    5:32

    At around 7:50am this morning the world famous Arecibo radio telescope collapsed after a series of failures weakened its structural integrity over the last few months. It's possible that the final collapse was triggered by transient loads from a seismic event, and we expect to find out more in the coming hours. Based on photos of the destroyed structure I've tried to lay out a sequence of events that explains the distribution of wreckage.

    Footage from the NSF showing the collapse as it happened

  • Battlefield 4 vs. Real Life: Incredible Video Compares Arecibo Collapse to Levolution

    2:00

    Battlefield 4's Rogue Transmission map was based on the Arecibo Observatory in Puerto Rico. A major levolution event allowed players to demolish the giant dish by snapping the cables and dropping the receiving platform. Now, it actually happened IRL and the National Science Foundation has released footage of the collapse. It's incredible how similar it looks to Battlefield 4's in-game destruction. Take a look for yourself.

  • Moment iconic Arecibo telescope collapsed caught in jaw-dropping footage

    1:07

    Another one bites the dust.
    Newly released footage shows the dramatic final moments of the Arecibo Observatory – the second-largest radio telescope on Earth – which collapsed earlier this week, in yet another major loss for humanity in 2020.
    The impending doom of the structure has been expected for a while now, since the auxiliary support cables first snapped in August, then in November, and now the cables connecting the hanging platform also gave way, leading to the catastrophic crash.
    The telescope had been used to send and detect waves radio waves from and send waves to outer space. In 1974, Arecibo sent the Earth’s most powerful broadcast, to see if any aliens might answer the call. It never heard back.

  • The wondrous life—and death—of Puerto Rico’s Arecibo Observatory

    4:35

    If a telescope’s 900-ton platform falls in a forest, it most definitely makes a sound. On 1 December 2020, a monumental collapse at Puerto Rico’s Arecibo Observatory unleashed a monstrous roar across the tree-covered karst landscape. In the rubble lay key components of a telescope that had delivered some of the most important scientific discoveries of the past half-century: indirect evidence of gravitational waves, a map of the surface of Venus, and detection of the first exoplanets.

    But Arecibo was more than just a scientific powerhouse. It was also a cultural icon. The telescope’s singular appearance led to cameos in movies, including Contact and Goldeneye. This video is a virtual tour of the technological advances that led to the telescope’s profound achievements—and a visual timeline of the momentous events that made up its life and death.

  • Worlds Largest Radar Astronomy Dish To Be Demolished!

    17:12

    The iconic Arecibo observatory has suffered a second cable break and now the engineers who were trying to reinforce the structure think that it's no longer safe to try and save the structure. The National Science Foundation which has been funding the installation for decades have decided to authorize demolition of the historic structure to avoid damage to other parts of the facility.

  • What Happened To The Arecibo Observatory?

    2:01

    Arecibo was the second largest ground-based telescope. This telescope had a 305 m inverted spherical dome which was made of 38,778 perforated aluminum panels. Since its completion in November 1963 it was used for the radar and radio astronomy and was a part of Search for extraterrestrial intelligence program.

    Recently some of its cables broke and 900-tonne platform fell, crashing on the dish.

    Drone footage shows the largest radio telescope in the world, the Five-hundred-metre Aperture Spherical Telescope​ (FAST) in the south-western province of Guizhou on Sunday, which is now the only one of its scale after the Arecibo Telescope collapsed in Puerto Rico on December, 1.

    FAST was completed in July 2016 and has been operating as the largest example of its kind since September 2016.

    The telescope's 500 metre (1,640 feet) fixed dish is located at a natural basin in the Dawodang depression and is made up of 4,450 triangular panels that allow it to monitor radio frequencies between 70 MHz and 3.0 GHz.

    On Tuesday, December 1, the famed giant telescope at Puerto Rico's Arecibo Observatory, believed to be world's second-largest, collapsed, when several support cables broke and came after plans had already been announced to decommission the dish after multiple cable failures in August and November.

  • Goodbye Arecibo, Your Spirit Is Now In Chinas FAST Telescope

    14:37

    On the island of Puerto Rico, nestled in the hills surrounding the city of Arecibo, stands the most famous radio telescope in the world, which over the years has become a Pop icon of scientific research.
    Without forgetting the strong emotional drive that the great antenna has always represented in the world for SETI research.
    But the news that more than any other seems to us able to give the measure of this extraordinary acceleration is that after just five years of work China has completed the construction of FAST - that is what with its 519 meters in diameter must be considered today the largest single antenna radio telescope in the world - thus appropriating a record that for more than half a century was held by the radio telescope of Arecibo with its parabola of 305 meters!

    -------------------------------------------------------------------------------------------

    The idea to build FAST (we will see later the meaning of this name) was born from a previous adhesion of China to the troubled Square Kilometer Array (SKA) project, when it was still assumed that the radio telescope wanted by the international scientific community could be built in the Asian country. In the end, it was decided that SKA would be built in two separate sites, in South Africa and Australia, and that it would use not a single mirror but a large expanse of smaller radio antennas. So, in 2006, China decided to set up on its own and take advantage of the experience gained to build its own radio observatory, extraordinarily large not only for reasons of political prestige, but also because of the need to impose a new dimensional standard to the scientific research of radio waves.
    But let's go in order, and enjoy step by step the stages of this extraordinary realization, starting from the description of the place where it was erected, i.e. Pingtang County, in the southern province of Guizhou.
    This part of the territory is formed by a continuous expanse of low mountains separated by cavities of karstic origin, mostly of almost circular shape.
    Just inside one of these, the Dawodang depression, 800 meters wide and chosen among many others scattered throughout China, it was decided in 2007 to house the antenna of a radio telescope similar to that of Arecibo, whose parabola, as we said at the beginning, was also built in a natural hollow. The area is definitely sparsely populated. The nearest cities are Anshun, more than 130 km northwest, and the great Guiyang, 150 km north, and therefore few are the artificial radio signals that could interfere with the observations. The obligation to respect the radio silence, also turning off cell phones, will have to be observed about ten kilometers before the arrival at the site, so that the Chinese government had to move to another location (not without controversy) the about 9 thousand people who lived less than 5 km from the installation.
    The staff of resident scientists and technicians, about seventy people in all, will move for emergencies with two helicopters always available on the square of the control center, while the visitors, who are expected to be very numerous, will almost all arrive by bus, since the area is forbidden to private traffic.

  • UPDATED! 12/4/2020 - Arecibo Observatory Historical Tribute

    6:20

    Hi. I'm a Gay Travel YouTuber located in Orlando, Florida. In this episode I pay tribute to the soon to be decommissioned Arecibo Observatory in Puerto Rico. This amazing world-famous site has been studying the universe for 57 years. I am sad to see it go away, so I put together this historical tribute video to the Arecibo Observatory. Let's Go!
    UPDATE: This tribute video now includes footage and information regarding the collapse of the observatory on December 1, 2020. Let’s Go!

  • Did an Earthquake Finish Off Giant Arecibo Mega-Telescope?

    1:10

    ARECIBO, PUERTO RICO — For 57 years, until 2016, the Arecibo Observatory was the largest telescope on Earth.

    But that legacy came crashing down last week, just when a regional earthquake’s wave train passed through the site.

    The collapse occurred when the tops of all three support towers snapped off, dropping the huge detector platform and its support cables onto the giant reflector dish below.

    This collapse had been expected since a second support cable broke on 6 November, following the previous failure of a support cable in August.

    Initial studies of the debris field indicate that the failure sequence started when a highly stressed cable in the weakened cable strand finally snapped, causing the central detector platform to detach and fall straight down.

    That platform’s support structure fell sideways into the side of the crater, suggesting that it stayed attached to the remaining two cables and swung sideways.

    Engineers assume the tops of all three support towers snapped off when one of the three cable strands finally failed completely, causing enormous lateral stresses in directions that the towers were not designed to support.

  • Footage shows catastrophic collapse of iconic Puerto Rico telescope

    1:37

    Dramatic video from captures the moment when a 816-tonne platform came crashing down on the Arecibo Observatory, shattering one of the world’s largest telescopes and striking a crushing blow to the global scientific community.

    The catastrophic collapse happened on Dec. 1, less than two weeks after the U.S. National Science Foundation (NSF) warned that such a disaster was imminent. The NSF had already shuttered operations at the facility after a suspension cable snapped and slashed a hole in the dish last month.

    The telescope was the largest of its kind when it opened in 1963, and it has contributed to all manner of astronomical discoveries over the years, from asteroids to planets to mysterious radio signals in space. It also won a place in pop culture as the set for such films as Contact and GoldenEye, the first James Bond movie starring Pierce Brosnan.

  • Dramatic Footage of the Collapse of Arecibo Observatory’s 305-Meter Telescope

    1:54

  • Arecibo Telescope : Before And During The Collapse

    4:07

    The catastrophic collapse of the Arecibo telescope on 1 December 2020 was captured by a control tower camera and a drone.

    Details :

    As the National Science Foundation described the collapse footage :

    This video, that starts with a view of the top of Tower 4, was taken from the vantage point of an Arecibo Observatory drone, utilized for monitoring the condition of Tower 4 support cables.

    Four cables are seen in the center of this video. The top cable does not support the telescope platform, but instead supports the catwalk described in the narrative for the previous video. The three lower cables are, from left to right, M4-1, M4-2, and M4-3.

    Note that a number of individual wire strands of the M4-1 and M4-2 cables are noticeably broken at the beginning of this video. The M4-3 cable does not appear to have any broken wires at the beginning of this video.

    The first indication of the coming failure is the breaking of another M4-2 wire, accompanied by a puff of smoke and chips of paint flying away from the surface of the cable. Four seconds later the entire M4-2 cable appears to disintegrate.

    The failure of M4-2 is followed a fraction of a second later by the demise of M4-1, followed a fraction of a second later by the failure of M4-3.

    The drone operator then swings the drone around to view the reflector dish and fallen platform, azimuth arm, Gregorian dome and the falling cables and catwalk.

    The top section of Tower 12, near the Visitor Center, can be seen tumbling down the hill to the left of the operations building. The Tower 12 backstay cables that connect the top of Tower 12 to the ground cause damage behind Tower 12, well away from the edge of the telescope dish.

  • Iconic Arecibo Observatory radio telescope collapses after cable broke

    1:43

    Iconic Arecibo Observatory radio telescope collapses after cable broke.

    A huge radio telescope in Puerto Rico that has long played a key role in astronomical discoveries collapsed on Tuesday, officials said. The Arecibo Observatory, made famous as the backdrop for a pivotal scene in the James Bond film GoldenEye and other Hollywood hits, had been shuttered since August after an auxiliary cable snapped and caused a 100-foot gash on the reflector dish. Then a main cable broke in early November, leading the National Science Foundation to declare just weeks later that it planned to close the radio telescope because the damage was too great. Many scientists and Puerto Ricans mourned the news, with some tearing up during interviews. Deborah Martorell, a meteorologist in Puerto Rico, tweeted early Tuesday: Friends, it is with deep regret to inform you that the Arecibo Observatory platform has just collapsed. It was the second largest radio telescope in the world and had been operating for more than half a century. Operated by the National Science Foundation through the University of Central Florida, the iconic observatory was made up of a fixed 1,000-foot-wide dish antenna built into a bowl-like depression that reflects radio waves from space to a 900-ton instrument platform suspended 450 feet above by cables stretching from three support towers For 57 years, the observatory played a leading role observing deep space targets, bodies in the solar system and, using powerful lasers, the composition and behavior of Earth's upper atmosphere. Before its collapse, the observatory withstood hurricanes and earthquakes, and played central roles in movies like GoldenEye and Contact.

  • Telescope Crashes Down at Arecibo Observatory in Puerto Rico

    1:13

    Video shows the moment the receiver of the telescope at the Arecibo Observatory in Puerto Rico fell and damaged the reflector dish on December 1.

    In the video, recorded by the National Science Foundation (NSF), the receiver can be seen starting to fall toward the ground as cables snap, spraying debris into the air.

    Another angle, filmed by the observatory’s drone, shows the wires and debris breaking away up close. The drone then retreats and swings around to view the reflector dish, fallen platform, and other damage below.

    The NSF reported the instrument platform of the Arecibo Observatory telescope, the second-largest single-dish radio telescope in the world according to space.com, fell on December 1.

    No injuries were reported on the date of the collapse.

  • Iconic Arecibo telescope in Puerto Rico collapses

    1:51

    A huge radio telescope in Puerto Rico that has played a key role in astronomical discoveries for more than half a century collapsed on Tuesday, officials said.
    The telescope’s 900-ton receiver platform fell onto the reflector dish more than 400 feet below.
    The US National Science Foundation had earlier announced that the Arecibo Observatory would be closed. An auxiliary cable snapped in August, causing a 100ft gash on the 1,000ft-wide (305m) reflector dish and damaged the receiver platform that hung above it. Then a main cable broke in early November.

    The collapse stunned many scientists who had relied on what was until recently the largest radio telescope in the world.
    “It’s a huge loss,” said Carmen Pantoja, an astronomer and professor at the University of Puerto Rico who used the telescope for her doctorate. “It was a chapter of my life.”

    Scientists worldwide had been petitioning US officials and others to reverse the NSF’s decision to close the observatory. The NSF said at the time that it intended to eventually reopen the visitor center and restore operations at the observatory’s remaining assets, including its two Lidar facilities used for upper atmospheric and ionospheric research, including analyzing cloud cover and precipitation data.

    The telescope was built in the 1960s with money from the US defense department amid a push to develop anti-ballistic missile defenses. It had endured hurricanes, tropical humidity and a recent string of earthquakes in its 57 years of operation.

    The telescope has been used to track asteroids on a path to Earth, conduct research that led to a Nobel prize and determine if a planet is potentially habitable. It also served as a training ground for graduate students and drew about 90,000 visitors a year.

  • How does Arecibos PLANETARY RADAR actually work?

    14:02

    Arecibo was condemned a couple weeks ago, and collapsed a couple days ago as a result of a minor earthquake and well-overdue maintenance. Unfortunately, this deprives the world of its largest Radar Telescope, and radar telescopes are awesome! I've had a really hard time in the past finding good descriptions of how radar astronomy actually works - how do you take a picture of something so far away that the beam diverges by the time it gets there, and diverges even more by the time it gets back!? The answer is math and approximation. Asteroid images are actually not any sort of photograph, but reconstructions based on timing and spectroscopy of radar signals.

    I'm really happy with how all the animations and whatnot came out, and I hope you like my explanation of delay-doppler imaging! I think it's an absolutely fascinating technique that's seen as just too counterintuitive to get a lot of recognition. Delay-Doppler images aren't really pictures, but they are sure valuable to researchers (and every human living on Earth under threat of asteroid impact!) Share this video with anybody who wants to appreciate how important Arecibo was, and what such an awesome unique instrument was capable of.

  • The Last Days of the Arecibo Observatory

    11:12

    WARNING: Footage of the collapse is from 8:43 to 10:10 min.

    On Friday, November 27, 2020, I visited the surroundings of the Arecibo Observatory where I saw the radio telescope one last time before its collapse. During this final visit, I had the opportunity to see it from different angles than the ones I was used to. I was also fortunate to interview some residents of the Esperanza neighbourhood who talked about their experiences living next to the world's greatest radio telescope. Just four days after this visit, the Arecibo Radio Telescope collapsed. Now we at Save The Arecibo Observatory, in partnership with the scientific community and the people of the world, are asking the U.S. Government to #RebuildTheAreciboObservatory and make it better than it was before. Help us out by signing and sharing the petition: and by following us on Facebook, Twitter, and Instagram (@SaveTheAO).
