"NASA Telescope Discovers Earth-sized Exoplanet with Lava Atmosphere"
NASA's TESS probe has discovered a young exoplanet, HD 63433 d, just 73 light-years away, which is almost identical in size to Earth but much hotter and likely half-covered in molten lava seas. This scorched world is the smallest and closest known young exoplanet, and its orbit is so snug that its year is only four days long. Astronomers hope to learn more about this intriguing planet, especially the side that never receives starlight, using the James Webb Space Telescope.
