Earth-like exoplanet with volcanoes found by NASA’s TESS and Spitzer telescopes
[ad_1]
Scientists using NASA's TESS (Transiting Exoplanet Survey Satellite) and Spitzer Space Telescope have made a remarkable discovery —an Earth sized exoplanet orbiting a star in a neighbouring galaxy. This finding provides the strongest evidence to date of active volcanoes existing beyond our solar system.
The observations indicate that this rocky planet has a rugged surface and experiences frequent eruptions, resembling Jupiter's moon Io, which is the most volcanically active body in our solar system. While the volcanism on the exoplanet wasn't directly observed, scientists inferred its presence from the gravitational interaction with the larger of the two planets also orbiting the star.
The gravitational pull of the larger planet may cause the newly identified exoplanet to flex a...
