The single star nearest to the Sun is called Barnard’s star. A team of researchers led by the Instituto de Astrofísica de Canarias (IAC), has recently detected a ‘sub-Earth’ orbiting it. This exoplanet, called Barnard b has at least half the mass of Venus and orbits rapidly around its star, so that its year lasts only a little over three Earth days. This new exoplanet is sixteen times nearer to Barnard’d star than Mercury is to the Sun, and has a surface temperature close to 125oC, so it does not have liquid water on its surface. This discovery, led by the IAC in collaboration with a number

An international research, in which the Instituto de Astrofísica de Canarias (IAC) has played a leading role, has found a planet of intermediate size between Earth and Venus orbiting a cool red dwarf 40 light-years away. The new world, named Gliese 12 b, lies within the habitable zone of its star, making it a promising candidate for the James Webb Space Telescope to study its atmosphere. The discovery was made possible thanks to observations from NASA's TESS satellite and other facilities such as CARMENES, at Calar Alto Observatory (CAHA), and MuSCAT2, installed at the Carlos Sánchez
