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.

Astronomers Discover Earth-Size Planet Covered in Volcanoes

Astronomers have discovered an Earth-sized exoplanet, LP 791-18 d, believed to be highly volcanic, potentially sustaining an atmosphere and allowing for water condensation on its cooler side. It orbits a small red dwarf star approximately 90 light-years away, sitting on the edge of the habitable zone. The planet's volcanic activity could be as frequent as Jupiter's moon Io, the most volcanically active body in our solar system. The discovery was made using data from NASA's TESS and Spitzer Space Telescope, and future studies are planned using the James Webb Space Telescope.

Newly Discovered Earth-Size Exoplanet Could be Covered in Volcanoes

LP 791-18 d, a newfound exoplanet about the size of Earth, may be covered in active volcanoes that could sustain an atmosphere, according to a new study. The planet is tidally locked, meaning the same side always faces its star, but the amount of volcanic activity occurring all over the planet could allow water to condense on the night side. LP 791-18 d is likely too volcanically active to host life as we know it, but it is an inviting target for astrobiologists and researchers interested in exoplanet atmospheres.
