Martian meteorite upsets planet formation theory

A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form. The work is published ...

Scientists find carbon-rich liquid water in ancient meteorite

Water is abundant in the solar system. Even beyond Earth, scientists have detected ice on the moon, in Saturn's rings and in comets, liquid water on Mars and under the surface of Saturn's moon Enceladus, and traces of water ...

Baked meteorites yield clues to planetary atmospheres

In a novel laboratory investigation of the initial atmospheres of Earth-like rocky planets, researchers at UC Santa Cruz heated pristine meteorite samples in a high-temperature furnace and analyzed the gases released.

Team uses mass spectrometry to study composition of meteorites

Scientists from Russia and Germany studied the molecular composition of carbonaceous chondrites—the insoluble organic matter of the Murchison and Allende meteorites—in an attempt to identify their origin. Ultra-high resolution ...

Key building block for organic molecules discovered in meteorites

Scientists from Japan and the U.S. have confirmed the presence in meteorites of a key organic molecule which may have been used to build other organic molecules, including some used by life. The discovery validates theories ...

Meteorites show transport of material in early solar system

New studies of a rare type of meteorite show that material from close to the Sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and gas from which the planets formed. The results, ...
