Astronomers Discover Exoplanet Orbiting Barnard's Star

**Astronomers have made an exciting discovery using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) — a new exoplanet orbiting Barnard’s Star, the closest single star to our Sun.** This discovery is significant because Barnard's Star is only six light-years away, making it the second-closest stellar system to us. The exoplanet, named *Barnard b*, has at least half the mass of Venus and orbits its star in just over three Earth days. Due to its proximity to Barnard’s Star, it experiences a surface temperature of approximately 125 °C, making it too hot for liquid water and thus not in the habitable zone. Nonetheless, the presence of such a low-mass exoplanet adds to our understanding of planetary systems around nearby stars. The detection involved observations over five years using ESO’s VLT located at Paranal Observatory in Chile. The team employed ESPRESSO, a precise instrument designed to detect the gravitational wobble caused by one or more orbiting planets. Additionally, other renowned instruments like HARPS, HARPS-N, and CARMENES contributed to the confirmation of the discovery. Interestingly, the research also hints at three more potential exoplanets around Barnard’s Star, awaiting further observations for confirmation. The upcoming ESO’s Extremely Large Telescope (ELT) with the ANDES instrument is set to revolutionize exoplanet research, allowing scientists to study additional rocky planets within temperate zones and delve into their atmospheric composition.
