Latest about gravitational waves
A nearby kilonova explosion could threaten all life on Earth. But don't worry, scientists say.
Collisions between neutron stars are the most powerful and violent events in the known universe. Would life on Earth survive a kilonova event?
Distorted crystals use 'pseudogravity' to bend light like black holes do
Researchers have used a special crystal to bend the trajectory of light like a black hole would, a phenomenon known as 'pseudogravity.'
LIGO gravitational wave detector breaks 'quantum limit' to find deep universe black hole collisions
The sensitivity of LIGO has squeezed the quantum limit, meaning it can now detect merging black holes and neutron stars on smaller scales and at greater distances than ever before.
New 'galactic atlas' offers stunning details of 400,000 galaxies near the Milky Way
The new Siena Galaxy Atlas is an information gold mine for astronomers and a free gallery of galaxy portraits for the public.
Why Einstein must be wrong: In search of the theory of gravity
Unlike physical theories describing the other three fundamental forces in physics, the general theory of relativity has only been tested in weak gravity.
What are gamma-ray bursts?
Reference Shrouded in mystery for decades, gamma-ray bursts are the brightest explosions since the Big Bang and emerge from only the most violent cosmic events.
How our Milky Way galaxy would look in gravitational waves (video)
The gravitational waves are emitted by ultracompact binaries of black holes, neutron stars and white dwarfs.
'Twisty' new theory of gravity says information can escape black holes after all
Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'
