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.

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

How to catch a gravity wave
Physicists have just announced finding gravity waves. The phenomenon was predicted a century ago by Einstein’s theory of general relativity. Here’s what it took to detect the waves.

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.

Visiting Pluto
Pluto has long been little more than a dark spot in the sky. Now NASA’s New Horizons spacecraft is about to fly by this dwarf planet. Along the way, it will collect unprecedented data on it.
