Black holes are not cosmic vacuum cleaners. They are among the universe’s most extreme objects - and come in different sizes.

A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously ...

The black hole was bigger than expected, and while the answer was hiding in plain sight, it still rewrites what we thought was possible. Reading time 4 minutes When LIGO broke news of an ...

If a new proposal by physicists bears out, the recent detection of a record-setting neutrino could be the first evidence of elusive Hawking radiation. (Nanowerk News) The last gasp of a primordial ...

Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from ...

What would a human see and feel while falling into a black hole? In this exclusive excerpt of his new book, "Facing Infinity," author and astrophysicist Jonas Enander tells us in terrifying detail.
