Few things in space are as bright as a supernova, but recently astronomer captured a flash out in the cosmos so great their ...

Suppose the birth of the universe was not a definite start, but a cosmological rebound far within a black hole? This radical idea has been picking up steam as new theoretical research, spearheaded by ...

A groundbreaking simulation reveals how neutron star mergers forge black holes, generate gamma-ray bursts, and scatter gold ...

Scientists find the secret to birth of earliest black holes in the Cosmos. A 20-year puzzle about how the earliest monsters were born in the universe may have just been solved .

Space.com: Startled astronomers peered through an apparent crack in the expanding bubble from an exploded star to glimpse what may be the youngest black hole ever detected.

About 98% of the star's mass collapsed and created a black hole with about 6.5 solar masses. M31-2014-DS1 isn't the only failed supernova, or candidate failed supernova, that astronomers have found.

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding ...

Space.com: The first black holes in the universe were born starving. A new study found that the earliest black holes lacked nearby matter to gobble up, and so lay relatively stagnant in pockets of ...

Study reveals that high-energy cosmic rays are born in magnetic fields during neutron star mergers, a prelude to black holes.

The Big Bang is often described as the explosive birth of the Universe – a singular moment when space, time and matter sprang into existence.

An amateur astronomer, good timing and a plucky companion star have come together to show direct evidence of a supernova forming a black hole-like object. This is a huge for the astronomical community ...
