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.
Talking to spacecraft is a normal occurrence at Arecibo Observatory, but sometimes the nuts and bolts are a little unconventional.

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.

In which we ponder the existence of others
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.
The shutdown of the federal government continues to claim casualties. Today, the Green Bank Telescope, Very Large Array, and Very Long Baseline Arrays all shut their doors, blinding us to the radio sky and scuttling long-term research projects.

The world's great telescopes capture stunning photographs of stars, nebulae, and other sky phenomena. In Europe to the Stars, authors Govert Schilling and Lars Lindberg Christensen share many such photos. But the real stars of this book are the great telescopes of the European Southern Observatory.
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.
A large asteroid is passing reasonably close to Earth in a few hours, and astronomers at the great radio telescopes at Goldstone and Arecibo are zapping it. The latest discovery: QE2, like many asteroids, is a binary.

Bruce Betts, Mat Kaplan, and asteroid tracker Robert Holmes on the Planetary Society Weekly Google Hangout. Mat discussed and showed pictures from his trip to the giant ALMA observatory and we'll be joined by asteroid tracker extraordinaire, Robert Holmes.

Great dinner and great conversation with staff of the National Radio Astronomy Observatory, topped by Chile's national drink.
