An article submitted for publication in the journal “Monthly Notices of the Royal Astronomical Society” reports the identification of an ultra-faint dwarf galaxy that was named Pegasus V near the Andromeda galaxy. A team of researchers conducted follow-up observations following the discovery made by an amateur astronomer and, using the GMOS instrument mounted on the Gemini North telescope in Hawaii, confirmed its existence. An interesting result of the observations is the very limited presence of elements heavier than hydrogen and helium, a discovery that led to the conclusion that it’s a kind of fossil of a primordial galaxy.
