What a burst of radio signals from space could mean for life in the stars

Astronomers are studying radio signals that have been detected by a telescope in China. And there are a lot of them to study, which is part of what scientists say makes this discovery so interesting.Over a period of 47 days in 2019, the telescope picked up more than 1,600 fast radio bursts, which is the most ever detected. The Show talked about this with Dan Marrone, a

Yes, You Can Look At The Sagittarius A* Black Hole - Just Don t Get Too Close

Astronomers have taken the closest look ever at the giant black hole in the center of the Milky Way. By combining telescopes in Hawaii, Arizona, and California, they detected structure at a tiny angular scale of 37 micro-arcseconds - the equivalent of a baseball seen on the surface of the moon, 240,000 miles distant. These observations are among the highest resolution ever done in astronomy. Using a technique called Very Long Baseline Interferometry (VLBI), a team of astronomers led by Doeleman employed an array of telescopes to study radio waves coming from the object known as Sagittarius A (A-star). In VLBI, signals from multiple telescopes are combined to create the equivalent of a single giant telescope, as large as the separation between the facilities. As a result, VLBI yields exquisitely sharp resolution.

anthony: what do they do down here? some pretty trippy shit as it turns out. this is the bicep in the dark sector lab and the south pole telescope, ten meters across mapping thousands of degrees of sky. today, they are installing the most advanced camera of its kind. dan: it s the third generation south pole telescope camera. 16,000 pixels, it weighs about 2,500 pounds. in a couple of days, we re going to pull it up into the telescope and try and see if we can hit the sky with it. anthony: very cool, it s like a bond villain stuff. dan: yeah, i know that s right. anthony: astrophysicists like
