A new galaxy has been discovered near the Andromeda Galaxy

The Andromeda Galaxy is the closest galaxy to the Milky Way. Visible from Earth with the naked eye or through telescopes, it is not alone, and European astronomers have recently discovered a new satellite galaxy located nearby.

Named Andromeda XXXVI, it is an ultra-faint dwarf galaxy. These celestial objects are small, poorly developed, and contain a large amount of dark matter. Thus, a team of astronomers led by Joanna D. Sakowska of the Institute of Astrophysics of Andalusia has confirmed the existence of this galaxy, which was discovered thanks to the Pan-Andromeda Archaeological Survey.

According to astronomers, it is located approximately 2.53 million light-years from the Milky Way, while Andromeda is located 2.5 million light-years away. This places the dwarf galaxy about 388,000 light-years from its host galaxy. Thus, studies show that it has a magnitude of -6.0 and a radius of 208 light-years. In addition, it is estimated to be 12.5 billion years old.

This discovery is important, as it allows astronomers to study the early stages of the universe. But that's not all, because dwarf satellite galaxies are also mysterious and very difficult to detect. As for Andromeda, it appears that there are more than a hundred satellite galaxies orbiting it. As a result, further observations and studies could be conducted to discover these new structures.
