300 new Intermediate-Mass Black Holes and 2,500 New Active Black Holes Discovered in Dwarf Galaxies
Using early data from the Dark Energy Spectroscopic Instrument (DESI), a team of scientists have compiled the largest sample ever of dwarf galaxies that host an actively feeding black hole, as well as the most extensive collection of intermediate-mass black hole candidates to date. This dual achievement not only expands scientists’ understanding of the black […]
‘Fastest-Feeding’ Black Hole of the Early Universe Found! But Does it Break the Laws of Physics?
The discovery could hold the key to the origin of supermassive black holes. The hungriest known black hole in the early universe has been found, thanks to teamwork between NASA’s James Webb Space Telescope (JWST) and Chandra X-ray Observatory. The black hole’s voracious appetite, which has allowed it to pile on more than seven million […]
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 […]
