### 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

### Beyond Pluto: A new 9th planet?

A giant planet, perhaps 10 times Earth’s mass, may be orbiting the sun from a great distance. Its existence, orbit and size are all surmised, based on strange effects seen in objects within the distant Kuiper Belt.

### 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.

### Scientists Say: Gravitational lens

A gravitational lens is an effect that occurs when a massive object lies between a viewer and something further away. The massive object’s gravity bends light arriving from the more distant object.
