Nearly a million ultraviolet sources appear in this mosaic of the Large Magellanic Cloud, which was assembled from 2,200 images taken by Swift's Ultraviolet/Optical Telescope. The 160-megapixel image required a cumulative exposure of 5.4 days. The image includes light from 1,600 to 3,300 angstroms тАФ UV wavelengths largely blocked by Earth's atmosphere тАФ and has an angular resolution of 2.5 arcseconds at full size. The LMC is about 14,000 light-years across. ...
