An international team of astronomers has used the James Webb Space Telescope (JWST) to observe a luminous dusty star-forming galaxy known as GN20. Results of the observational campaign, published April 26 on the arXiv preprint ...
Astronomers studying stellar nurseries, the birthplaces of stars, in the Milky Way have found that nearly half the stars in the galaxy are formed in binary/multiple stellar systems (think twins, triplets, quadruplets).
