The supermassive stars, dubbed 'celestial monsters', are believed to have existed only 440 million years after the Big Bang.

The measurement helps refine the dividing line between neutron stars and black holes.

The universe was simply different when it was younger. Recently astronomers have discovered that complex physics in the young cosmos may have led to the development of supermassive stars, each one containing up to 100,000 times the mass of the sun.

Astronomers used gravitational lensing and supercomputers to identify the colossal black hole, which is among the largest ever found.

This black hole is 15 million times the mass of our Sun and that is a humongous one.

The discovery of a hidden primordial black hole, which formed just 750 million years after the Big Bang, suggests that it may be the 'tip of the iceberg' of the cosmic monsters hiding in the early universe.

A rare supermassive black hole found hiding at the dawn of the universe could indicate that there were thousands more of the ravenous monsters stalking the...

Astronomers have detected 21 rare systems with widely separated neutron stars and sun-like stars. These binaries are "one in a million" and challenge dead...

A huge solar filament eruption has hurled a coronal mass ejection (CME) toward Earth. The CME is expected to hit Earth on Sept. 19 and may trigger extensive ...

Scientists have finally identified the progeny of that supernova - an enormously dense object called a neutron star. Two instruments on the James Webb Space...

At the heart of our Milky Way galaxy lurks a supermassive black hole about four million times the mass of the sun, called Sagittarius A*. But since NASA's...

Astronomers have found the most massive stellar black hole to date in the Milky Way galaxy, and it was all due to the wobble of the object's companion star.

With help from the James Webb Space Telescope, scientists have identified a possible lead on how some supermassive black holes get so incredibly big.

Gaia BH1 has a mass of 9.62 times the mass of the Sun and is orbited by a bright Sun-like star at about the same distance as our planet orbits the Sun.

The star may be up to 50 times the mass of our sun.

The enormous black hole is four million times the mass of our sun
