NASA and ESA’s Hubble Space Telescope offers a unique ultraviolet perspective when studying celestial objects, and this has been utilised by an international team of astronomers to produce a survey of nearby star-forming galaxies. Combining fresh and archival Hubble observations, astronomers have now created the most comprehensive collection of star-forming galaxies with extremely high-resolution images.
50 spiral and dwarf galaxies within our local universe were observed as part of this survey, and it can now be used as a valuable resource when scientists wish to study the complexities of star formation and galaxy evolution. The project has been designated the Legacy ExtraGalactic UV Survey (LEGUS) and has collected a large amount of data on this matter. LEGUS has accumulated star catalogues for each of the LEGUS galaxies and cluster catalogues for 30 of the galaxies, also included are images of the galaxies themselves.
“There has never before been a star cluster and a stellar catalogue that included observations in ultraviolet light,” explains survey leader Daniela Calzetti of the University of Massachusetts, Amherst, United States. “Ultraviolet light is ...
