An article published in the journal “Nature” reports the discovery of the most distant single star, nicknamed Earendel. A team of researchers used data collected during the RELICS (Reionization Lensing Cluster Survey) program using the Hubble Space Telescope to search for the brightest galaxies dating back to the first billion years of the universe’s life. A large galaxy cluster cataloged as WHL0137-08 distorted the image of very distant galaxies in a gravitational lensing effect to the point that it can detect a single star about 12.9 billion light-years away from Earth. Earendel’s study, whose mass was estimated to be at least 50 times the Sun’s, will help to better understand the formation and evolution of the very first generations of stars in the universe.
