When Million-Degree Gas Is Safe
Submitted by chandra on Mon, 2008-07-28 13:26Last week, we put out a press release on an elliptical galaxy known as NGC 4649. Using Chandra data, a group of astronomers measured the temperature of the hot gas around the galaxy to come up with an independent way to measure the size of the gigantic black hole at the center. You can read more about the details in the press release.
