An Unusual Fossil Galaxy Discovered on Outskirts of Andromeda – Could Reveal History of the Universe

Gemini North  telescope reveals a relict of the earliest galaxies.

An amateur astronomer with keen eyes scanning archived data processed by NSF's NOIRLab's Community Science and Data Center has found a unique ultra-faint dwarf galaxy

 dwarf galaxy on the edges of the Andromeda Galaxy

In subsequent studies by experienced astronomers utilising the International Gemini Observatory, a Program of the NSF's NOIRLab

the dwarf galaxy known as Pegasus V was found to contain very few heavy elements and is likely to be a fossil of the first galaxies.

The NSF's NOIRLab's capabilities have assisted in the discovery of a strange ultra-faint dwarf galaxy on the fringe of the Andromeda Galaxy. 

The galaxy, known as Pegasus V, was first found during a systematic hunt for Andromeda dwarfs led by David Martinez-Delgado of the Instituto de Astrofisica de Andaluca in Spain

At the time, amateur astronomer Giuseppe Donatiello had spotted an odd "smudge" in data in a DESI Legacy Imaging Surveys image.

The picture was shot with the Victor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory

which is equipped with a Dark Energy Camera made by the US Department of Energy (CTIO)

 The Community Science and Data Center at NOIRLab, which manages the Community Pipeline, processed the data (CSDC).
