Gravitational Waves
Gravitational waves could show what’s happening inside a star as it’s going supernova
It's kind of hard to see inside a star as it's blowing up, because of the whole "blowing up" part,…
Could a tabletop experiment detect gravitational waves and determine the quantum nature of gravity?
A tabletop gravitational wave detector could take decades to build, but it could answer the most fundamental questions in physics.
Why Can Black Hole Binaries Have Dramatically Different Masses? Multiple Generations of Mergers
Black hole mergers with very different masses tell us how small mergers can give rise to even larger ones.
The Moon is an Ideal Spot for a Gravitational Wave Observatory
A prestigious pair of astronomers have published a paper recommending that a gravitational wave observatory be built on the far…
A Black Hole Popping Out of a Traversable Wormhole Should Give Off a Very Specific Signal in Gravitational Waves
Gravitational wave astronomy has changed the way we view the cosmos. In only a few years we have observed the…
Why Pulsars Are So Bright
When pulsars were first discovered in 1967, their rhythmic radio-wave pulsations were a mystery. Some thought their radio beams must…
New Simulations Show How Black Holes Grow, Through Mergers and Accretion
One of the most pressing questions in astronomy concerns black holes. We know that massive stars that explode as supernovae…
Astronomers Detected a Black Hole Merger With Very Different Mass Objects
In another first, the latest gravitational wave event to be detected came from the merger of two black holes of…
NASA Chooses 4 New Astronomy Space Missions for Additional Study
NASA recently selected four new missions for development that will study gravitational waves, supernovae, relativistic jets, and exoplanet habitability.
14% of all the Massive Stars in the Universe are Destined to Collide as Black Holes
Einstein's Theory of General Relativity predicted that black holes would form and eventually collide. It also predicted the creation of…
