Summary[edit]

Description

The NASA/ESA Hubble Space Telescope has captured the glow of new stars in these small, ancient galaxies. Pisces A is on the left and Pisces B is on the right.

Astronomers estimate that less than 100 million years ago both galaxies doubled their star-formation rate. An analysis of the stars' colours reveals that the galaxies contain about 20 to 30 bright blue stars. The blue colour is a sign they are young, less than 100 million years old. Each galaxy contains about 10 million stars.
