February 18, 2019 - Lion’s Share of Hot Young Stars
Lion’s Share of Hot Young Stars Using the unparalleled sharpness and ultraviolet observational capabilities of the Hubble Space Telescope, astronomers have created the most comprehensive high-resolution ultraviolet-light survey of star-forming galaxies. The Legacy ExtraGalactic UV Survey (LEGUS) contains about 8,000 clusters and 39 million hot blue stars occurring in 50 local galaxies within 60 million light-years of Earth, in both visible and ultraviolet light. This LEGUS image shows spiral galaxy M66, about 35 million light-years away in the constellation Leo (the Lion). Like all the galaxies in LEGUS, M66 is undergoing vigorous star and star-cluster formation. These hot young stars, which shine brightly in ultraviolet light, are key to understanding galactic evolution.
