A flock of stars
The glittering specks in this image, resembling a distant flock of flying birds, are the stars that make up a dwarf galaxy.
Captured in this new image from the NASA/ESA Hubble Space Telescope, dwarf galaxy ESO 540-31 lies just over 11 million light-years from Earth, in the constellation of Cetus (The Whale). The background of this image is full of many other galaxies, all at vast distances from us.

Dwarf galaxies are among the smaller and dimmer members of the galactic family, typically containing only around a few hundred million stars. Although this sounds like a large number, it is small when compared to spiral galaxies like our Milky Way, which are made up of hundreds of billions of stars.
