Shell Galaxy Glows in the Night Sky (Photo)

Billions of galaxies dot our observable universe, and this image captures a less-commonly seen example, Arp 227. Warren Keller and Steve Mazlin took this image from Star Shadows Remote Observatory PROMPT2 CTIO near La Serena, Chile. "As we're fortunate enough to image from a premium location in the southern hemisphere, we often gravitate to the beautiful island universes of the south," Keller wrote in an email to Space.com.
