Mineralogy points to large, water-rich parent asteroid for carbonaceous chondrite meteorite. A Southwest Research Institute-led team of scientists has identified a potentially new meteorite parent asteroid by studying a small shard of a meteorite that arrived on Earth a dozen years ago...

Water on Mars absorbed like a sponge, new research suggests. 2 new articles have shed light on why there is, presumably, no life on Mars. IAlthough today’s Martian surface is barren, frozen and uninhabitable, a trail of evidence points to a once warmer, wetter planet, where water flowed freely – and life may have thrived. The conundrum of what happened to this water is long standing and unsolved. However, new research suggests that this water is now locked in the Martian rocks.

Read MoreNew research predicts that Earth has more than 1,500 undiscovered minerals and that the exact mineral diversity of our planet is unique and could not be duplicated anywhere in the cosmos. Minerals form from novel combinations of elements. These combinations can be facilitated by both geological activity, including volcanoes, plate tectonics, and water-rock interactions, and biological activity, such as chemical reactions with oxygen and organic material.
Nearly a decade ago, Hazen developed the idea that the diversity explosion of planet’s minerals from the dozen present at the birth of our Solar System to the nearly 5,000 types existing today arose primarily from the rise of life...
