Bringing samples of the Moon and Ryugu to Earth, and mourning further damage to the Arecibo Observatory.

Nadia Drake: NSF investigating how to shut down Arecibo

Reporter Nadia Drake has been following the status of Arecibo very closely, and recently wrote two articles explaining what it means that the National Science Foundation has begun an environmental review process for the giant radio telescope.

The Cosmic Microwave Oven Background

Over the past couple of decades the Parkes Radio Telescope in Australia has been picking up two types of mysterious signals, each lasting just a few milliseconds. The source of one of these signals may have finally been found—and an unexpected source at that.

Green Bank Telescope Helps Out an Old Friend

The Green Bank Telescope has been called into emergency service to play radar ping-pong on a close-by asteroid with Arecibo Observatory’s 100-meter William E. Gordon radio telescope.

Arecibo Observatory operational after repairs to fix earthquake damage

Early in the morning on January 13, 2014, a 6.4 magnitude earthquake struck beneath the Atlantic Ocean north of Puerto Rico, damaging Arecibo Observatory, the world’s largest single-dish radio telescope. The telescope is now operational after repairs and scientists have resumed observations. However, the future of Arecibo Observatory remains unclear due to funding uncertainties in the federal budget.

Returning Explorers

Cosmos returns in fine form in its penultimate episode. Sagan explores the historical and scientific precedents for the search for extraterrestrial life (SETI) and our human desires to not be alone in the universe.

How radar really works: The steps involved before getting an image

Arecibo Observatory is known for its 1000-foot diameter telescope and its appearances in Goldeneye and Contact. Aside from battling Bond villains and driving red diesel Jeeps around the telescope (grousing at the site director about the funding status of projects is optional), several hundred hours a year of telescope time at Arecibo go toward radar studies of asteroids.
