"Its occurrence is like finding a tropical seed in Arctic ice – indicating either an unexpected local environment or ...

A study of enstatite chondrites (one shown), a type of meteorite similar to the material that formed Earth, suggests that Earth’s primordial building material had plenty of water, even though ...

Remember how enstatite chondrite is basically identical to proto-Earth’s geological composition?

Earth's chemical makeup is similar to waterless rocky bodies called enstatite chondrites, which suggests the planet may have formed from these types of materials. For years, scientists thought ...

A meteorite found in Antarctica in 2012 suggests Earth may have formed with the materials needed to make water, a new study hints.

Bryson, a co-author on the study published earlier this month in Icarus, and his colleagues investigated an enstatite chondrite meteorite from Alaska known as LAR 12252.

They feared that water on present-day Earth had contaminated the meteorites with hydrogen. Last year, the researchers in France reported that the hydrogen in enstatite chondrites is bonded to sulfur.

Enstatite chondrites have similar oxygen, titanium and calcium isotopes as Earth, and this study showed that their hydrogen and nitrogen isotopes are similar to Earth's, too.

Section of the enstatite chondrite meteorite Sahara 97096. Throughout its formation, Earth accreted material that was isotopically most similar to this group of enstatite meteorites.

A new study by the Centre de Recherches Petrographiques et Geochimiques, France, examined a meteorite called an enstatite chondrite for signs of hydrogen.

A rare kind of meteorite known as enstatite chondrite resembles Earth's composition roughly 4.5 billion years ago. 25,020 people played the daily Crossword recently. Can you solve it faster than ...
