Unusual Shape of Exploded Star Puzzles Scientists


Penn State astronomers have used NASA's Chandra X-ray Observatory to produce a new image of a ghostly exploded star with an unusual shape in a galaxy near the Milky Way. Astronomers think the object may be the remains of a white-dwarf star that disintegrated in a thermonuclear explosion, known as a Type Ia supernova, but it does not look like other likely Type Ia remnants found in our own Milky Way galaxy.

The research that led to the new image of this object was led by Penn State University astronomers Sangwook Park and Jae-Joon Lee, and was presented at the 214th meeting of the American Astronomical Society in Pasadena, California, on 9 June 2009. The strange object, known as SNR 0104-72.3 (SNR 0104 for short), is in the Small Magellanic Cloud galaxy, which is a neighbor of our Milky Way galaxy.

Drama in the Heart of the Tarantula


A new image of the Tarantula Nebula, a massive star-forming region close to the Milky Way, was released on 11 December 2008 by the Chandra X-Ray Observatory. The image, which will help astronomers to understand how massive stars shape other worlds, represents almost 31 hours of observing time with the Chandra X-Ray Telescope -- three times longer than previously recorded.
