ARECIBO TELESCOPE:

Puerto Rico’s Arecibo Telescope was built in 1963.
It is the second-largest single-dish radio telescope in the world. It was in news recently because of its collapse.
It is owned by the US National Science Foundation.
It is known for its finding that Mercury rotates in 59 days and not 88 days (original calculation).

About Arecibo Telescope

The Arecibo Telescope has one of the most powerful radar employed to observe asteroids, planets, ionosphere.
The telescope has discovered the first exoplanets, prebiotic molecules in distant galaxies and first millisecond Pulsar.
The Telescope had served as a hub in the search of extra-terrestrial life and has picked up several radio signals from alien civilisations.
It has played a major role in tracking killer asteroids heading towards the earth.
In 1993, the scientists Joseph Taylor and Russell Hulse were awarded the Nobel Prize in physics.
With the help of the observatory they monitored a binary Pulsar. It was the first evidence for the existence of gravitational waves.
