Meteorites likely wiped out Earth’s earliest life
Enormous meteorites appear to have slammed into Earth several times early in its history. Each mega-smashup would have boiled off oceans and obliterated any bit of life.

Smooshed diamonds: A window into exoplanets?
Scientists have compressed diamonds more than ever before. Their carbon may give clues to what conditions might be like deep within planets way beyond our solar system.

First mega-Earth found
Astronomers are puzzled by Kepler-10c. This exoplanet is rocky like Earth — but as massive as Neptune. And that challenges their accepted ideas about how planets form.

Distant planet may boast the longest year
On a planet far, far away, a single pass around its sun may seem to last forever.

A ‘Goldilocks’ world?
Scientists have spotted a faraway planet that is nearly the size of Earth and could host liquid water. It's too far to visit, but astronomers say the galaxy could be littered with such potentially habitable worlds. Don't hang up yet, E.T.

Surprising rings circle comet-asteroid hybrid
It’s too small to be a planet. Yet this planet wannabe still resembles Saturn-like giants. It’s the smallest solar system inhabitant to, like them, host rings of orbiting ice.

Jupiter’s long-lasting storm
Most studies of Jupiter’s centuries-old Great Red Spot suggest this giant storm should have petered out after a few decades. A new study traces the storm’s staying power to the vertical movement of its gases.

The comet that came in from the cold
Comet ISON is hurtling toward the sun at breakneck speed. During this first (and possibly last) trip around the sun, it will either shoot back into space or be torn apart.
