'Fossil galaxy' near Andromeda

Amateur astronomer finds petrified surprise near Andromeda Galaxy.

Giuseppe Donatiello detected Pegasus V in historical data from a DOE camera meant to seek for dark energy.

Astronomers interested in his findings used a larger Hawaiian telescope, Gemini North.

Pegasus V may be a "fossil" of the primordial galaxies, full with ancient stars.

The galaxy was initially seen by the Chilean Vctor M. Blanco 4-meter Telescope. Donatiello was searching for Andromeda dwarf galaxies when he noticed Perseus V.

Scientists suggest that the new galaxy, which contains few heavy elements, must be ancient.
