Astronomers have observed a supermassive black hole in a distant quasar and made a stunning discovery -- it's spinning one-third the speed of light.
As we say goodbye to February, let's take a look back at this month's profound discovery of gravitational waves.
Now the elusive ripples in spacetime have been found, scientists are planning for a rich future for using gravitational wave observatories to unmask the warped side of cosmos.
The pair of black holes the set off the first detection of gravitational waves through space may have been spawned by the death of a single, massive star.
Black hole theoretical physicist Stephen Hawking has some thoughts on the discovery of gravitational waves.
We now have the ability to listen in on the most violent events in our cosmos. Thank you Einstein!
The merging black holes generated a gravitational wave signal from 1.3 billion light-years away -- but which direction did they come from?
What are they? Why are they important? Why should we care?
