Spinning black holes may ‘sing’ during a collision
The massive black hole in the movie Interstellar would create a unique gravity-wave signal when gobbling a smaller partner.

This planet’s lightning storms are like nothing on Earth
Radio waves from a faraway exoplanet could signal intense lightning storms there.

Key sugar for life on Earth could have formed in space
Ribose, a sugar in RNA, may have formed in space and then rained down on a young Earth, a new study suggests.

Dwarf galaxy spawned heavy elements
A study of nine stars in the dwarf galaxy Reticulum II found heavy elements. They had been produced after a violent stellar event sparked a chemical chain reaction.

Hurricane at this galaxy’s center is wicked fast
The gale-force winds around one quasar whip by at almost 200 million kilometers per hour. That’s 625,000 times faster than the strongest hurricanes on Earth.

Black hole smashup sent out ‘yottawatts’ of power
When two black holes collided, they released a lot of energy in gravity waves. How much? How about 36 septillion yottawatts of power!

Say hello to gravity waves
Einstein predicted these waves 100 years ago. Scientists have finally proven him right.

Gravity waves detected at last!
Albert Einstein predicted gravitational waves 100 years ago. Now scientists have detected them coming from the collision of two black holes.

Explainer: What are gravitational waves?
Albert Einstein had predicted that large catastrophes, like colliding black holes, should produce tiny ripples in the fabric of space. In 2016, scientists reported finally detecting them
