The exploration era for the new James Webb Space Telescope (JWST) is getting hot—volcanically hot.

A multidisciplinary group of Cornell researchers has modeled and synthesized lava in the laboratory as the kinds of rock that may form on far-away exoplanets. They developed 16 types of surface compositions as a starter catalog for finding volcanic worlds that feature fiery landscapes and oceans of magma.

Their research, “Volcanic Exoplanet Surfaces,” was published in the forthcoming November 2022 edition of Monthly Notices of the Royal Astronomical Society.

“We have synthesized compositions t...
