Only two robotic missions have made it to the Swift Planet, but they were crucial for upending many false assumptions of that sun-scorched world

Antarctic meteorite (HUT 18036) is found partially submerged in ice, as opposed to resting atop the surface. 

Meteorites Are Becoming Harder to Find as They Sink Into Antarctica's Melting Ice

The disappearing space rocks are burying valuable clues into the history and composition of our solar system, according to a new study

The Lyrids are slated to peak on April 21-22, though the moon will be nearly full, which could make the meteors more difficult to see.

Why We Love Eclipses

Two perspectives on the astronomical phenomenon that has fascinated humans for as long as we’ve been watching the skies

The darker areas across Titan's equatorial regions represent its dunes, as taken by the Cassini rover.

Titan's Massive Dunes May Be a Comet and Moon Graveyard From the Early Solar System

A new modeling study suggests the dark dunes on Saturn's largest moon are made of tiny particles created by crashing comets and moonlets billions of years ago

Mars' orbit has an impact on Earth's oceans and climate in cycles of 2.4 million years, new research finds.
