Volcanic exoplanet found using Spitzer and TESS data.

Using data from Spitzer and TESS, scientists have discovered an Earth-sized exoplanet, LP 791-18 d, that could potentially be covered with volcanoes. The planet is located in the constellation Crater, approximately 90 light-years away from Earth, and is tidally locked to its star. The gravitational pull of a neighboring exoplanet, LP 791-18 c, is causing an increase in volcanic activity on LP 791-18 d. The team believes that the planet's volcanism and location within the habitable zone means that the formation of an atmosphere is possible, and the temperatures on the night side of LP 791-18 d could be low enough for water to condense on the planet's surface.
