10 years of Milky Way activity
*Cool. I began downloading it, but have other programs running so will have to wait until later to download the entirety.
A new X-ray movie of the Milky Way Galaxy shows stars erupting and black holes pulsating over a full decade of time.
The movie, obtained exclusively by SPACE.com, shows the sky blinking in ways optical telescopes can't see. While stars are often pretty steady in their emissions of visible light, some vary greatly in their X-ray emissions.
The data was gathered by NASA's Rossi X-ray Timing Explorer, launched in 1995. The movie is a product of NASA and MIT. It shows stars seeming to blink in and out of existence, while other sources remain constant.
Invisible black holes and dense neutron stars turn on and off, or vary over time, as they suck material off companion stars.
