A star detonated as a supernova… twice

All supernovae are massively energetic stellar explosions. The classic supernovae are massive stars that explode near the end of their lives, leaving behind either a neutron star or a black hole, and a remnant made of expanding gas and dust. But supernovae are not all the same. Some occur in binary systems, and they’re called […] The post A star detonated as a supernova… twice appeared first on Knowridge Science Report.
