![]() Patrick Taylor, USPRA senior scientistīut Arecibo's work came to a crashing halt in 2020. I watched my entire professional career fall into a sinkhole. We've observed hundreds of near-Earth asteroids with Arecibo," Taylor said.Īrecibo spotted the first confirmed exoplanets around the pulsar PSR 1257+12, during a sky survey in 1992. "Arecibo is not the only facility for this, but it was by far the most powerful and the most sensitive instrument to use. "In the last 10 years, we greatly expanded how much observing we did of near-Earth asteroids, with Arecibo and with radar in general," Taylor told Live Science. ![]() Arecibo collected critical data on their physical properties, satellites and orbits, enabling NASA to calculate the risk an asteroid might pose to Earth, said LPSC presenter Patrick Taylor, a senior scientist with the Universities Space Research Association at the Lunar and Planetary Institute in Houston, Texas. The telescope also revolutionized the use of radar for study and tracking of asteroids that orbit close to our planet. It even verified Albert Einstein's theory of general relativity and inferred the presence of gravitational waves, the researchers reported at LPSC. The observatory scrutinized Saturn's rings and mapped the surface of the moon. It detected the first known exoplanet orbiting a pulsar, in 1990. ![]() Arecibo helped astronomers measure the rotations of Mercury and Venus for the first time. ![]()
