Black holes are on a continuum of ultradense objects that form from the remnant cores of dead stars after they run out of fuel and collapse under gravity. White dwarfs form from stars up to about eight times the mass of the Sun, and have an upper mass limit of about 1.4 times the Sun's mass.

Chinese researchers have discovered a promising mass-gap black hole using radial velocity and astrometry methods. The study was published online in Nature Astronomy on Sept. 10, and was conducted by a team led by Dr.

Astronomers led by Song Wang from the Chinese Academy of Sciences, have discovered an unusual celestial phenomenon, potentially the smallest black hole ever detected. The discovery was made approximately 5,

Researchers in China have uncovered a low-mass black hole within the elusive mass-gap, defying previous scientific consensus. By combining radial velocity and astrometry, they identified this black hole in a wide binary system,

Chinese astronomers have discovered a rare, small black hole in a unique binary star system, providing new insights into the formation of black holes. The research, led by Dr. Wang Song from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC),

The energetic streams are together 23 million light-years in length—roughly as long as 140 Milky Way galaxies lined end to end

The largest known black hole jets, 23 million light years across, have been discovered in the distant universe. This pair of particle beams launched by a supermassive black hole is over a hundred times larger than our galaxy,

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes. The star cluster in question is called Palomar 5. It's a stellar stream that stretches out across 30,

Astronomers have made a groundbreaking discovery: a swarm of over 100 stellar-mass black holes is traversing through the Milky Way within the star cluster known as Palomar 5. This extraordinary cluster,

Black holes hold some of the universe’s greatest mysteries, with giant empty spots in space sucking in whatever enters their gravitational pull. However, the mystery is now growing as astronomers are now saying there could be a swarm of black holes moving across the Milky Way.
