A supermassive black hole at the center of galaxy J1007+3540 has restarted its jet emission after roughly 100 million years ...

Strange matter only occurs under very specific circumstances -- and astrophysicists are getting closer to understanding what ...

What if some black holes aren’t black holes at all? A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon. Instead, the ...

Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's ...

We don't know whether theorized primordial black holes (PBH) are real. If they are, they formed in the very early universe, when physics was much different. They had no stellar progenitors and were ...

An artist's concept of a tidal disruption event (TDE), which happens when a star passes close to a supermassive black hole. The gravity of the black hole pulls material from the star and launches a ...

Smithsonian Starstruck lets visitors walk through the Big Bang, brush past the Sun, and gaze into a black hole, all without ...
