When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

A new study proposes that a crash between Titan and another moon spawned Hyperion and, much later, destabilized Saturn’s inner moons into rings.

Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward Earth from 8 billion light-years away and was spotted thanks to a weird ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

A team of scientists says it's possible to use tiny ripples in space and time, or gravitational waves, to measure the rate at which our universe is expanding. This could solve one of the biggest ...

How did life begin on Earth? While scientists have theories, they don’t yet fully understand the precise chemical steps that ...

The next asteroid won’t come with a warning siren. What happens after it’s discovered could determine everything.

Smiling Friends Ending was the most-read story on Bleeding Cool yesterday. Lying In The Gutters is the daily runaround.

Saturn’s largest moon, Titan, may have been born in a colossal cosmic crash. New research suggests Titan formed when two older moons slammed together hundreds of millions of years ago—an event so ...

The Universe is continually expanding, and scientists measure its expansion rate, the Hubble Constant, using two main methods: electromagnetic methods (using light from stars, galaxies, or supernovae) ...

NASA officials and planetary defense experts have been discussing a major gap in Earth’s asteroid detection efforts: a large number of medium-sized near-Earth asteroids remain undiscovered. Reports ...
