Oct 12, 2012 - X-ray Satellites Monitor the Clashing Winds of a Colossal Binary
The hottest and most massive stars don't live long enough to disperse throughout the galaxy. Instead, they can be found near the clouds of gas and dust where they formed - and where they will explode as supernovae after a few million years. They huddle in tight clusters with other young stars or in looser groupings called OB associations, a name reflecting their impressive populations of rare O- and B-type stars.

Oct 5, 2012 - NASA's Swift Satellite Discovers a New Black Hole in our Galaxy
NASA's Swift satellite recently detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously unknown stellar-mass black hole.

Oct 5, 2012 - Swift Cycle 9 GI Program
NASA received 158 proposals (slightly up from last year), requesting a total observing time of 13.2 Ms and $4.3M in funds for 866 targets. The Swift Cycle 9 Peer Review will be held in December to evaluate the merits of submitted proposals and choose those that are recommended for funding and observing time.

Apr 13, 2012 - NASA's Swift Monitors Departing Comet Garradd
An outbound comet that provided a nice show for skywatchers late last year is the target of an ongoing investigation by NASA's Swift satellite. Formally designated C/2009 P1 (Garradd), the unusually dust-rich comet provides a novel opportunity to characterize how cometary activity changes at ever greater distance from the sun.

Feb 24, 2012 - Andromeda Galaxy Pops Up Ultraluminous X-ray Sources
Researchers using NASA's Chandra X-ray Observatory, Hubble Space Telescope, Swift Gamma-ray Burst Explorer and the European Space Agency's XMM-Newton Observatory have been studying an object known as an ultraluminous X-ray source -- ULX, for short -- in the neighboring Andromeda galaxy (M31). Scientists have long debated the nature of these super-bright X-ray sources, and Chandra's 2009 discovery of a nearby ULX in Andromeda sparked intense interest.
