![]() Losing Arecibo Observatory would create a hole that can't be filled, scientists say Scientists want to build a new, very different Arecibo Telescope to replace fallen icon Rather than replace Arecibo's 1,000-foot (305 meters) dish with a cutting-edge instrument that would surpass others and meet these vital needs, the new NSF education center is supposed to inspire students and the public about STEM activities, as Arecibo has for decades. "The center would be like a zoo without animals, or a biology laboratory without microscopes." research data - whether it's about planetary security, national security or deep space - will be in totalitarian hands. While one hopes relations with China will improve, in the meantime it's alarming that U.S. Its useful surface is a little larger than Arecibo's was, but it lacks a radar and it suffers from far more radio interference. Sadly, radio astronomers who want anything comparable to Arecibo have only one choice: China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) telescope. Arecibo's work in the field has also brought surprises and illuminated mysteries, like the first discovery of a binary pulsar, which led to a Nobel Prize, and the first discovery of an exoplanet. In addition, radio astronomy brings us insights into the universe, revealing fundamental physics that affects how airplanes and houses are built, how inventors approach their tasks and more. Arecibo has played a key role in studying many of them. There are 2,000 such "potentially hazardous" near-Earth asteroids, according to NASA. His discoveries will inform the launch of a new spacecraft, as well as adding to our knowledge of a potential threat. ![]() The Observatory's unique capabilities were evident even a few days after NSF's short-sighted decision, announced in October, when accounts of Arecibo scientist Sean Marshall's observations of asteroid Phaethon's orbit filled the press on Oct.
