Image shows the disappearance of Star forming Black Hole |
Astronomers have watched a birth of new black hole. These observations made through Hubble and Spitzer Space Telescopes. The spotted star became a black hole instead of going to supernova state. Most of the star form black hole after a stage of supernova, but this star was strange and faded directly to a black hole. This was discovered by a group of astronomers from Ohio state university and the Ohio Eminent Scholar in Observational Cosmology.
As many as 30 percent of such stars, it seems, may quietly collapse into black holes and no supernova required. Kochanek explained that they don't see supernova from most massive stars. This star named NGC-6946 is 23 times larger than Sun located in a Spiral Galaxy which is 22 million light years away. And it was nick named "Fireworks Galaxy" because supernova frequently happens there. Observation starting from 2009 of this star named N6946-BH1, began to brighten weakly. By 2015, it appeared to have winked out of existence.
