A detailed Summary of Astronomy


Evidence that the heavens house a previously unknown type of black hole was reported by scientists yesterday. Data from NASA's Chandra X-Ray Observatory revealed a hole was some 600 light-years from the center of the starburst galaxy M82. The brightness of the x-ray source indicates that this moon-size hole has the mass of at least 500 suns, making it intermediate between stellar black holes and the supermassive black holes found at the centers of galaxies. "This opens a whole new field of research," said Martin Ward, a lead author on one of three papers to be published on the subject. "No one was sure that such black holes existed, especially outside the centers of galaxies."

Earlier data from the Roentgen Satellite and the Advanced Satellite for Cosmology and Astrophysics


A new unknown type of black hole was discovered on September 12, 2000. It was found to be 600 light-years of the Starburst Galaxy M82. An x-ray source indicates that the moon-size black hole has the mass of at least 500 suns, "making it intermediate between stellar black holes and the supermassive black holes found at the center of galaxies" (Scientific America, 1). Scientists were shocked at this discovery, for they didn't know that these types of black holes existed. Scientists believe this black hole may have been due to a collapsed "hyperstar" or the growth of a smaller black hole through mergers with others nearby.

Our school has an astronomy/space type course, however it could be so much stronger. Considering how 0much information there is to discuss about the planets and galaxies, as well as the discoveries that occur everyday, our course cou
