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

Black holes in a pair of merging galaxies, known as UGC4211, are devouring gas and dust that is "being displaced by the ...

For victims, recovery hampered by delayed reporting, traceless withdrawals, fictitious mule addresses — and redressal process ...

The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

A cataclysmic variable star was found as part of a project using two telescopes from opposite sides of the world.

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

The Hubble Space Telescope is making waves again, this time for a snapshot of a spiral galaxy located 250 million light-years ...

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

"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly advanced technological civilization," Harvard's Avi Loeb writes.

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

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

Priyamvada Natarajan has spent decades exploring some of the universe’s most persistent mysteries, particularly the unseen ...
