Astronomers have identified TOI-2155b, a rare celestial object about 80.6 times Jupiter’s mass, lying on the boundary between a brown dwarf and a star. Its study could improve understanding of how stars ignite and where the stellar mass threshold begins
NASA's James Webb Space Telescope found fingerprints of 'dimethyl sulphide' and 'dimethyl disulphide' on distant exoplanet named K2-18 b -- known to be produced on Earth by microbes. The molecules provide the strongest evidence yet that life may exist on a planet outside our solar system, even as how they formed on that exoplanet remain unknown
