Researchers announced that they had found a new type of celestial object, which they suspected was a new class of black holes. A group of scientists led by Rosanne Di Stefano of the Harvard-Smithsonian Center for Astrophysics had examined data collected by NASA's Chandra X-ray Observatory. The team had studied x-rays emitted by enigmatic objects located in nearby galaxies, finding that the volume of x-rays emanating from these objects was comparable to or greater than the volume emitted by relatively warmer, larger hard x-ray sources, such as neutron stars and supermassive black holes. The findings indicated that the newly discovered objects could be a type of black hole that the researchers termed “quasi-soft” x-ray sources.
