Curiosity Discovers First Meteorites on Mars - And they are Huge and Made of Heavy Metal

NASA’s Curiosity rover found this iron meteorite called “Lebanon” while driving across Mars on May 25, 2014. This mosaic combines imagery from the ChemCam and Mastcam instruments. Credit: NASA/JPL-Caltech/LANL/CNES/IRAP/LPGNantes/CNRS/IAS/MSSS See our meteorite mosaics below

Heralding another notable achievement, NASA’s industrious rover Curiosity has simultaneously discovered her 1st meteorites on the Red Planet. NASA has […]

Is This New Evidence for Ancient Life on Mars?

The debate over possible evidence for life on Mars is one of the most hotly debated subjects in space science, and some news released Feb. 27 is sure to add fuel to the fire. Studies of a Martian meteorite, known […]

Gravity Controls Enigmatic Moon's Geysers

These images from NASA’s Cassini spacecraft show how the pull of the planet affects the amount of material ejected by geysers on Saturn’s moon Enceladus. It turns out that the moon launches more spray when it is farther away from Saturn. Image Credit: NASA/JPL-Caltech/University of Arizona/Cornell/SSI

Saturn’s 314-mile-wide icy moon Enceladus has been teasing […]

Be afraid – but not too afraid. It’s true that at some point, if we don’t take steps to prevent it, a big dumb object is going to smash into the Earth so hard that civilization as we know it will be […]

Scientists Seek Source Of Life's Lopsided Left-Handedness

This is an artist’s concept of excess left-hand aspartic acid created in asteroids and delivered to Earth via meteorite impacts. The line at the bottom is a chromatogram showing that left-hand aspartic acid (tall peak in the center, with diagram of left-hand aspartic acid molecule on top) was four times more abundant in the […]
