- Carnegie Mellon University-led team conducts most detailed cosmological simulation to date
06-28-2007 · EurekAlert!
Using a new computer model of galaxy formation, researchers have shown that growing black holes release a blast of energy that fundamentally regulates galaxy evolution and black hole growth itself. The model explains for the first time observed phenomena and promises to deliver deeper insights into our understanding of galaxy formation and the role of black holes throughout cosmic history. The results were generated by an international team of investigators.

- Chandra discovers cosmic cannonball
11-28-2007 · EurekAlert!
One of the fastest moving stars ever seen has been discovered with NASA's Chandra X-ray Observatory. This cosmic cannonball is challenging theories to explain its blistering speed.Astronomers used Chandra to observe a neutron star, known as RX J0822-4300, over a period of about five years. During that span, three Chandra observations clearly show the neutron star moving away from the center of the Puppis A supernova remnant at over 3 million miles per hour.
