For decades, scientists have believed there should be black holes that fall between two well-known types. On one end are ...

Pulsars, like black holes, are formed from dying stars. Weighing up to twice the mass of the sun, they are just 20km across and can spin up to 700 times a second.

Supermassive black holes that seem too large to exist in the early universe may have grown from primordial black holes formed ...

Whereas scientists have observed plenty of stellar mass black holes and SMBHs, evidence of IMBHs has been a lot harder to ...

The scientists studied a black hole system consisting of a stellar-mass black hole and a sun-like star orbiting each other. In this system, 5 or 6 jets occur over a period of about 20 days, making ...

New evidence and properties of intermediate-mass black holes have been discovered with help from RIT researchers, as ...

A new University of Leicester study shows how the uncontrolled growth of a distant supermassive black hole (SMBH) is revealed ...

Astronomers detect an ultramassive black hole weighing 36 billion suns in the galaxy LRG 3-757, a record thanks to ...

Very massive stars (VMSs), which typically have masses about 100 times that of our own sun, are critical components in our ...

A new census reveals that 35% of supermassive black holes are hidden behind dust, disrupting major galactic models.

Could a decades-long debate about the mysterious movements of stars in Omega Centauri, the largest star cluster in the Milky Way, finally be resolved? Could a decades-long debate about the ...
