Gravitational Waves
On its Next run, LIGO Will be Able to Probe 8 Times as Much Space
Materials science has once again come through for space exploration. Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have developed…
In Addition to Gravitational Waves, is There any way to Detect Merging Black Holes
If two black holes merge in the middle of space, and nobody's around to see it, does it really happen?…
Neutron Stars Have Mountains, They’re Just a Fraction of a Millimeter High
The universe has some very extreme places in it - and there are few places more extreme than the surface…
Gravitational-Wave Detector Could Sense Merging Primordial Black Holes With the Mass of a Planet, Millions of Light-Years Away
A new idea for detecting gravitational waves might allow us to discover planet-mass primordial black holes.
Black Hole-Neutron Star Collisions Could Finally Settle the Different Measurements Over the Expansion Rate of the Universe
If you've been following developments in astronomy over the last few years, you may have heard about the so-called "crisis…
One Idea to Explain Dark Matter – Ultralight Bosons – Fails the Test
A study of rotating black holes show that some spin so quickly because dark matter particles haven't slowed them down.
You Thought Black Hole Event Horizons Looked Strange. Check out Binary Black Hole Event Horizons
Binary black holes lens light so strongly it's difficult to simulate how they would appear. A new simulation shows us…
A new way to see Inside Neutron Stars
Astronomers study neutron stars using a method made famous by jazz singer Ella Fitzgerald.
Black Holes Simulated in a Tank of Water Reveals “Backreaction” for the First Time
Water simulations that small gravitational waves near a black hole can significantly change the black hole's behavior.
Physicists Figure out how to Make Gravitational Wave Detectors “Hear” 6x More Universe
Gravitational wave detectors are limited by fundamental quantum noise - an incessant "hum" that they cannot ever remove. But now…
