The most astounding part is perhaps that the faint galaxy is in Milky Way’s neighbourhood, situated 136 million light-years away.
Indian astronomers have discovered a Ghost like Galaxy which was unexplored until now. The galaxy is a star-forming region & was shrouded by a bigger & brighter galaxy. The most astounding part is perhaps that the faint galaxy is in Milky Way’s neighbourhood, situated 136 million light-years away.
A team of researchers from the Indian Institute of Astrophysics in Bengaluru spotted the galaxy while studying a known galaxy NGC6902A that was interacting with this faint galaxy.
It was first spotted when astronomers saw blue emission in the southwest outer region of the NGC6902A galaxy. Turns out, these emissions were coming from young stars classified as Type O and Type B – one of the biggest and short-lived stars in the galaxy.
When scientists saw excessive light, they probed its cause and found a faint galaxy hiding nearby. This newly discovered galaxy is extremely faint – about ten times fainter than surrounding night sky. Owing to this, it is extremely difficult to spot.
The new galaxy has been officially named UVIT J2022, a study published in the journal Astronomy & Astrophysics revealed. This research implies that there could be other fainter galaxies interacting with larger and brighter ones waiting to be discovered.
