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.

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.

Scientists Say: Yottawatt
On Earth, scientists measure energy use in watts. When you have lot of those watts — one million billion billion — you have a yottawatt.

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!

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

Einstein taught us: It’s all ‘relative’
One hundred years ago, a German physicist shared some math he had been working on. In short order, his theory of relativity would revise forever how people viewed the universe.
