Water vapor is detected on exoplanet K2-18b, a super-Earth which is located about 111 light-years away from Earth. It is the first time water has been confirmed on an exoplanet within the circumstellar habitable zone of a star.
Astronomers from the Max Planck Institute for Astronomy announce the discovery of red dwarf star GJ 357 and its three confirmed exoplanets in the Hydra constellation, one of which (GJ 357 d) is highly likely to be a super-Earth planet located in the system's circumstellar habitable zone where life can exist. The discovery was made using NASA's Transiting Exoplanet Survey Satellite (TESS).
A study on exoplanet populations combining decades of data from several different observatories detects 118 possible exoplanets orbiting nearby red dwarfs, including new discoveries around nearby stars Wolf 359, Lacaille 9352, Struve 2398 B, and Luyten's Star.
Wolf 503b, a super-Earth exoplanet twice the size of Earth, is discovered orbiting Wolf 503 ru 503 145 light years away by American, German, and Canadian researchers via the NASA Kepler Space Telescope.
