Located just north of Regulus (seen as the bright spray off the bottom of the image), the Leo-I galaxy is a dwarf spheroidal satellite galaxy to our own Milky Way and is the most distant of the fifteen Milky Way satellites known. This three-color view spans a 0.5x0.5-degree region and was created from 45 separate images from the Sloan Digital Sky Survey. The SDSS g-, r-, and i-bands map to the image's blue, green, and red channels, respectively. The mosaic was created with the IRSA On-Demand Image Mosaic Service and Montage v3.0.
