Ushering in IYA2009, Chandra-StyleSubmitted by chandra on Tue, 2009-01-06 14:16
There are some exciting, yet different, Chandra-related events happening at the American Astronomical Society (http://aas.org/) meeting in Long Beach, CA today. First, there was a press conference this morning to announce new results on Cassiopeia A that bring this supernova remnant "to life". One result shows how Cas A has changed from 2000 â€“ just after Chandraâ€™s launch â€“ through until late 2007. This is the first time scientists have been able to watch as a supernova remnant changes like this over time.
