Arecibo Observatory was originally intended for ionospheric research and radio astronomy, but the former was of more interest to ARPA, which wanted to study and monitor the Earth’s ionosphere as part of its Defender Program to develop ballistic missile defenses.
Who had the idea to build Arecibo?
The Arecibo Observatory had its origins in an idea of Professor William E. Gordon, from Cornell University, who was interested in the study of the Ionosphere. Gordon’s research during the fifties led him to the idea of radar back scatter studies of the Ionosphere.

Why is the Arecibo Observatory in Puerto Rico so unique?
Unusually flexible scientific thinking has always been one of Arecibo’s strengths. Although the massive radio dish was originally designed for atmospheric scientists to study the ionosphere, the facility blossomed to play a key role in two other scientific communities as well: radio astronomy and planetary science.
Why can’t Arecibo be rebuilt?
Scientists doubt that document can support a rebuilding effort at Arecibo because the telescope collapsed after the committee’s deadline for community input. “Nobody expected that big money might be needed for a rebuilding,” Rankin said.

What really happened to the Arecibo telescope?
By mid-November, the U.S. National Science Foundation (NSF), which owns the site, decided that the telescope was too unstable to be repaired — but before the agency could demolish it, gravity did the job. On Dec. 1, 2020, the platform fell, smashing through the delicate dish.
Why was the radio telescope destroyed?
Last month, the US National Science Foundation (NSF), which owns the observatory, had announced it would shut down the telescope permanently, citing safety concerns over its instability, and damage too extensive to repair. The final collapse happened just before 8 a.m. local time on 1 December. No one was injured.

Will there be a new Arecibo telescope?
According to a group of scientists, the “Next Generation Arecibo Telescope” will be the new name of the fallen telescope. At the moment, there are no specifications about the design of the telescope. … Pinilla-Alonso said that they came up with the design two months after the great collapse took place.
How much would it cost to rebuild Arecibo?
WASHINGTON — A report by the National Science Foundation estimates it will cost up to $50 million to clean up the damage from the collapsed Arecibo radio telescope, but that it is still too soon to determine whether or how to rebuild the famous observatory.
How much would it cost to repair the Arecibo Observatory?
Cleaning up the collapsed radio telescope at the iconic Arecibo Observatory in Puerto Rico could cost between $30 million and $50 million, according to the National Science Foundation (NSF).
Why was Arecibo built in a sinkhole?
Arecibo’s large dish, built in a natural sinkhole in Puerto Rico’s karst landscape, was meant to serve as a giant radar for probing it. Upgrades after NSF took over the facility in 1969 made it alluring for more kinds of science.
What is Arecibo known for?

What is an observatory used for?
An observatory is a facility for observing or monitoring environmental conditions or phenomena on Earth or in space. Meteorological observatories examine the weather. Geophysical observatories research the movements of Earth’s crust.
Is Arecibo broken?
One of astronomy’s most renowned telescopes — the 305-metre-wide radio telescope at Arecibo, Puerto Rico — is closing permanently. Engineers cannot find a safe way to repair it after two cables supporting the structure broke suddenly and catastrophically, one in August and one in early November.
How did Arecibo get damaged?
During its 57 years of operation, Arecibo was damaged on several occasions, often by earthquakes and hurricanes. In 2014, an earthquake damaged another of its main cables, which was subsequently repaired. In 2017, Hurricane Maria damaged both the dish and one of the antennas.
Why is the Yerkes Observatory important?
Yerkes Observatory, “the birthplace of modern astrophysics”, in Williams Bay, Wisconsin is the home of the 40-inch diameter “Great Refractor”, the world’s largest lens telescope, completed in 1897. From 1897 to 1908 the Great Refractor was the largest astronomical telescope in the world.
Who owns Yerkes?
The University of Chicago donated the Yerkes Observatory to a foundation dedicated to preserving the facility. The Yerkes Future Foundation took over ownership of the observatory and roughly 50 acres of surrounding land on Friday, May 1.
What did the Yerkes Observatory discover?
Among the prominent scientists to study at Yerkes was Edwin Hubble, who did his graduate work at Yerkes. The Yerkes telescope also discovered the atomic explosion of the star named T-Corona Borealis and took pictures of globular star clusters, which helped with the study of star motion.
Who owns Arecibo Observatory?
