Astronomers discover 4 new planets orbiting Earth's nearest star—do they have life too?
Astronomers have discovered four small planets orbiting Barnard's Star, the second-closest star system to Earth, using advanced instruments and techniques, shedding light on planetary formation and the search for life beyond our solar system.
After 100 Years of Searching, Astronomers Confirm Four Planets at Barnard’s Star
Astronomers have discovered not one, but four tiny planets orbiting Barnard’s Star, our cosmic neighbor. These planets, each about a fifth the mass of Earth, whip around their host star in just days—likely too hot for life but a major milestone in detecting smaller planets.
Scientists discovered that methyl halides, a gas produced by microbes, could be a biosignature for life on distant planets.
