Quartz is one of the most common crystals on Earth

Meteorite strikes may create unexpected form of silica

Piece of the meteorite Sahara 97096 (about 10 cm long), an enstatite chondrite that contains about 0.5 weight % of water. If Earth formed entirely of this material, it would have received 23 times the total mass of water present in the Earth's oceans. Credit: L. Piani, Museum of Natural History in Paris

Meteorite strikes made life on Earth possible

Cosmic pearls: Fossil clams in Florida contain evidence of ancient meteorite

Polar ice caps on Mars are a combination of water ice and frozen CO2. Like its gaseous form, frozen CO2 allows sunlight to penetrate while trapping heat. In the summer, this solid-state greenhouse effect creates pockets of warming under the ice, seen here as black dots in the ice.
