"We've detected X-rays from so many fantastic objects, such as very young massive stars and stars so small that they may evolve into brown dwarfs," said Gordon Garmire, Evan Pugh Professor at Penn State University, University Park. The discovery of such a wealth of X-ray stars in the closest massive star-forming region to Earth (only 1,500 light years away) is expected to have a profound impact on our understanding of star formation and evolution. ![]() The Orion region is a dense congregation of about 2,000 very young stars formed during the past few million years. The discovery-the richest field of X-ray sources ever obtained in the history of X-ray astronomy-will be presented on Friday, January 14, at the 195th national meeting of the American Astronomical Society in Atlanta, Georgia. NASA's Chandra X-ray Observatory has resolved nearly a thousand faint X-ray-emitting stars in a single observation of young stars in the Orion Nebula. ![]() Chandra Finds X-ray Star Bonanza in the Orion Nebula
