Listening through a telescope the Chandra X-ray observatory hears a black hole.

In space, you can hear a black hole sing (WaPo link). Using the Chandra X-Ray Observatory, astrophysicists have detected a supermassive black hole in the Perseus Cluster which has been "playing" a B-flat for 3 billion years.

Fascinating as this seemingly counterintuitive discovery (sound carrying through space) is, the real significance lies in that these "sound waves" may explain why the superhot gases in such regions aren't cooling down and forming more stars.

Massive explosion rocks NASA And Pasadena, and a few other places, too. It's not every day you get to watch a black hole form. Includes cool animation (.mov file). Seems the gamma ray burst detector picks up two or three significant events every month or so.

Astronomers claim a massive black hole orbits our galaxy sweeping from the outskirts to the core while cryptozoologists claim bigfoot was documented on a 1930s vegetable packing crate.

The stars in the core of our galaxy are moving damned fast. [more]
