New research is shedding light on what researchers call "lite" intermediate-mass black holes, which are smaller, but still ...

Astronomers working with the European Southern Observatory's (ESO) Very Large Telescope (VLT) have detected patterns showing ...

Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this ...

How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 billion times the mass of the sun.

Here’s a look at the life of renowned theoretical physicist, cosmologist, astronomer and mathematician, Stephen ...

Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.

Predicted by Einstein and dismissed as undetectable, gravitational waves were finally heard in 2016. Now, with observatories ...

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

Black holes, once purely theoretical, are now observable phenomena, offering insights into the universe. Their intense ...

These black holes are the most distant and stable objects we know. Using a technique called very long baseline interferometry ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...
