Discovery triples known active black holes in dwarf galaxies, doubles intermediate black hole candidates, and challenges ...
Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum ...
Using the James Webb Space Telescope, scientists witnessed a brilliant light show at the heart of our Milky Way galaxy.
Scientists have discovered more about the process that causes black holes to "leak" energy to their surroundings, finding the faster they spin, the more energy is extracted.
A massive filament of gas and dust, designated X7, has been elongated during its long approach to the Milky Way galaxy's supermassive black hole Sagittarius A*. See W.M. Keck Observatory imagery of ...
