a cluster of stars in the dark sky

"Peekaboo" Dwarf Galaxy HIPASS J1131–31 Caption: Tiny galaxy HIPASS J1131–31 peeks out from behind the glare of star TYC 7215-199-1, a Milky Way star positioned between Hubble and the galaxy. One hundred years ago, this fast-moving foreground star would have appeared directly in the line of sight, and the "Peekaboo" galaxy would not have been detectable at all.
