A Better Eyeshot Of The Makeup Of Ancient Meteorites

A team of Japanese and American scientists has visualized meteorite components at resolution powers much higher than ever before. Their efforts resulted in a much better look at – and enhanced understanding of – substances inside carbonaceous chondrites, the organic-containing meteorites that land on Earth. These substances include hydrogen, carbon, nitrogen and water, all of …Read More

Three New Minerals Discovered In A Unique Meteorite

Researchers led by mineralogist Chi Ma have identified three new minerals in a tiny sample of the Khatyrka meteorite. The meteorite, recovered in pieces from the Koryak Mountains in eastern Russia in 1979 and 2011, made news in recent years for containing the first three natural quasicrystals ever found. (A quasicrystal is a phase of …Read More

New Evidence For A Water-Rich History On Mars

Mars may have been a wetter place than previously thought, according to research on simulated Martian meteorites conducted, in part, at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). In a study published today in the journal Nature Communications, researchers found evidence that a mineral found in Martian meteorites—which had been considered as …Read More
