- 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 - 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.

- 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.
