Even from beyond the grave, Arecibo is still contributing to new discoveries. Back in October, researchers released a “treasure trove of data” from what was then the world’s most powerful radio telescope on the radar signatures of near-Earth asteroids (NEAs). Not only will these observations help defend the planet if any of those asteroids happen to be hazardous, but they can also help the burgeoning asteroid mining industry scan for targets.Continue reading “Arecibo Studied 191 Asteroids That Flew Past the Earth. All the Data are Available in a new Paper”
The National Science Foundation announced last week that it won’t rebuild or replace the iconic Arecibo Observatory in Puerto Rico, which collapsed in 2020. Instead, the NSF says they have solicited calls for proposals to build a multidisciplinary educational center at the site.
Additionally, the plans do not appear to allow for any future science or observing from the other facilities at the Arecibo site, as the NSF said they will not provide any “operational support for current scientific infrastructure, such as the 12-meter radio telescope or Lidar facility,” also on location.
The announcement has been met with disappointment and disbelief.Continue reading “Arecibo Won’t Be Rebuilt”

Observational astronomy is dependent on its data, and therefore also dependent on the instruments that collect that data. So when one of those instruments fails it is a blow to the profession as a whole. The collapse of the Arecibo Telescope last year after it was damaged by Hurricane Maria in 2017 permanently deprived the radio astronomy world of one of its primary observational tools. Now a team at the National Radio Astronomy Observatory (NRAO) hopes to upgrade an existing telescope at the Green Bank Observatory in West Virginia to replace the failed Puerto Rican one and provide even more precise images of near Earth objects in the radio spectrum.Continue reading “A New Radar Instrument Will Try To Fill the Void Left By Arecibo”
The National Science Foundation released two different videos today showing the collapse of the Arecibo Observatory, as it happened on December 1, 2020. Needless to say, the footage is heartbreaking.Continue reading “Now you can Watch Actual Video of Arecibo Collapsing … If You Dare”
Early this morning, the 900-ton instrument platform suspended above the Arecibo Observatory collapsed and crashed down on the iconic telescope’s giant dish. The collapse occurred at about 7:55 a.m. local time, officially ending any possible hopes of refurbishing the famous observatory in Puerto Rico.
Images of the collapse and subsequent damage started appearing on social media this morning; the National Science Foundation then confirmed via tweet that indeed the observatory had collapsed. They also said no injuries were reported.Continue reading “The Arecibo Observatory Platform Has Collapsed”
Another main cable that supports the Arecibo Observatory broke last week, falling onto the reflector dish and causing more damage. This is the second time a cable has snapped on the iconic radio observatory in just three months.
The new damage is an unfortunate and devastating setback for the observatory, just as repairs from the first accident were about to begin.Continue reading “A Second Cable has Failed at Arecibo, Causing Even More Damage to the Radio Observatory”
On Aug. 10th, a little over a month ago, the iconic Arecibo Observatory suffered serious damage when an auxiliary cable broke and struck the reflector dish. This cable struck the observatory’s Gregorian Dome on its way down and twisted an access platform before landing on the reflecting dish itself. The impact created a gash over 30 meters (100 feet) in length and forced the observatory to shut down until repairs could be made.
Since then, teams have been busy working to stabilize the structure and determine the cause. These teams are made up of technicians from the observatory and the University of Central Florida (UCF), which manages the facility for the National Science Foundation (NSF). For the past few weeks, they have been meeting with experts from various fields and laying the groundwork for an investigation and a rigorous repair schedule.Continue reading “An Update on the Damage to the Arecibo Observatory”
