The Arecibo Observatory has earned a reputation as the largest and most sensitive radio telescope in the world. It was the site of the world’s largest single-unit radio telescope until FAST began observations in 2016. Thanks to two major upgrades throughout its 57 years of life, and a series of new instruments, the AO had been at the forefront of astronomical, planetary and atmospheric studies. With FAST, researchers will be able to measure extremely low-frequency Nahertz gravitational waves for the first time. On December 1, 2020, the 900-tonne platform that held most of the instruments of the Arecibo Observatory (AO) at a height of more than 500 feet above the ground came crashing down. He also encouraged me to take my time with research—except during my final year for the thesis, since it was graded,” she laughs. This is what Space.com has to say about the dish: " The 1,000-foot-wide (300 m) Arecibo got up and running in 1963 . “He is so kind and brilliant and respectful and really listens to students,” says Osase Omoruyi, an ex-mentee. These have motivated a new (and much larger) generation of Puerto Rican students to pursue degrees in a wide range of science and engineering fields. Sacrifices were made to get FAST constructed: A 65-person village was relocated from the valley to make room for the telescope[15] and an additional 9,110 people living within a 5 km radius of the telescope were relocated to create a radio-quiet area. 'We are working very hard on Arecibo model 2,' he said. FAST stands for Five-hundred meter Aperture Spherical Telescope. So I concentrated on electromagnetic signals with long wavelengths, from infrared to radio waves.” Héctor’s path was first influenced by the Arecibo telescope, and then directed to the phenomena that it could elucidate. He was on a trip his senior year of high school. He obtained his PhD in astronomy from Harvard University and his bachelor in physics from Cornell University.
