New research suggests that black holes may actually be "frozen stars," bizarre quantum objects that lack a singularity and an event horizon, potentially solving some of the biggest paradoxes in black hole physics.

For decades, a black hole that has as much spin or charge as it can given it mass was considered mathematically impossible. A new proof reveals otherwise.

Chinese astronomers have uncovered a low-mass black hole that challenges long-held astrophysical theories. This black hole, part of a binary system known as G3425, has a mass of about 3.6 solar masses,
