Missing Link Found: Supernovae Give Rise to Black Holes or Neutron Stars (Video)
When massive stars reach the end of their lives, they collapse under their own gravity so rapidly that a violent explosion known as a supernova ensues. Astronomers believe that, after all the excitement of the explosion, what is left is the ultra-dense core, or compact remnant, of the star. Depending on how massive the star […]
Chandra X-ray Observatory Discovers Giant Black Holes on Collision Course
A new study using NASA’s Chandra X-ray Observatory has tracked two pairs of supermassive black holes in dwarf galaxies on collision courses. This is the first evidence for such an impending encounter, providing scientists with important information about the growth of black holes in the early Universe. By definition, dwarf galaxies contain stars with a […]
