Arecibo replacement downsized

摘要

Astronomers at the iconic Arecibo Observatory in Puerto Rico have revised their plans for a telescope to replace the original facility, which dramatically collapsed in 2020. The so-called Next Generation Arecibo Telescope (NGAT) would, if funded, involve building a phased array of small parabolic antennas to try to maintain the island’s position at the forefront of astronomy.
