The Indarch Meteorite is a possible building block of the planet Mercury. Scientists cooked up rocks in the lab to produce materials similar to it, in an effort to understand Mercury's chemical composition and evolution. Courtesy Vahe Martirosyan, CC Attribution Share Alike 2.0.

Rice University researchers used the rare Indarch meteorite as a laboratory stand-in for Mercury, offering a new way to study why the innermost planet is so chemically unlike Earth, Venus, and Mars.

Key Takeaways
