Take a Look: A New Ghost Galaxy Discovers by Indian Astronomers.

A group of researchers from the Indian Institute of Astrophysics in Bengaluru, together with foreign partners, discovered the galaxy while analyzing NGC6902A, a known interacting galaxy.

The galaxy was undetected so far since it lies in front of a much brighter galaxy and has a "ghost-like" appearance in the optical images because of its low disk density, according to the Ministry of Science and Technology.

The galaxy is classified by low surface brightness that is at least ten times fainter than the surrounding night sky, making it difficult to be spotted before.

However, as optical telescopes become more and more powerful, they are capable of picking up this faint brightness being emitted from these galaxies. 

The researchers have named the galaxy UVIT J202258.73-441623.8 ( UVIT J2022 for short).

The newly discovered galaxy is around 136 light-years away from Earth.

Faint galaxies form about 15 per cent of the mass of the universe. Faint galaxies are also called low surface brightness galaxies or ultra-diffuse galaxies. These galaxies are at least ten times fainter than the night sky around them.
