The Earth and artistic concepts showing the exoplanet Gliese 12 b in possible versions ranging from no atmosphere to a very thick atmosphere like that of Venus

Two articles, one published in the journal “Monthly Notices of the Royal Astronomical Society” and one in “The Astrophysical Journal Letters”, report independent confirmations of the discovery of the exoplanet Gliese 12 b, which has a size very close to the Earth’s but orbits a red dwarf that has a mass and size that are around a quarter of the Sun’s. Two teams of researchers used observations conducted by NASA’s TESS space telescope and confirmations obtained with other instruments to verify the existence of Gliese 12 b. The available information doesn’t reveal if it has an atmosphere but several factors make it a good candidate for a follow-up search with the James Webb Space Telescope.
