The puzzle of methane on Mars has taken an interesting new twist: For the first time, the gas has been detected within Martian meteorites. The finding adds another layer to the ongoing controversy over […]

Building Blocks of DNA Can Potentially Be Created in Space, According to New Study

An artist’s impression of the material that has been ejected from the Supernova 1987A in the neighboring Large Magellanic Cloud. The violent deaths of stars during supernova exoplosions, expel most of the stellar material into interstellar space, reseeding it with large amounts of dust as well as complex organic compounds which form the basis […]

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

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 […]

Meteors flashing across the sky are a common sight here on Earth, but of course they are not limited to only our planet; these bits of rocky debris, smaller pieces of asteroids and comets known as meteoroids, can be found just […]

NEOs: Too Close For Comfort?

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 […]
