IIA researchers discover a new ‘Ghost-Galaxy’

Do you know that there are an estimated 100 billion galaxies in the universe and, with the improved telescope technology in space, the number is likely to increase to about 200 billion! It is an inevitable fact that the deeper we look into the cosmos, the more galaxies we will discover. A study from 2016 estimates that the observable universe contains two trillion – or two million million – galaxies. But the question is, what have we found so far and how our scientists are probing into them?

Recently, a team of researchers from the Indian Institute of Astrophysics, Bengaluru have discovered a faint but star-forming galaxy, around 136 million light-years away. The discovery was not easy, as this galaxy was hiding in front of a much brighter, bigger galaxy. The optical images indicate that the galaxy has a ‘ghost-like’ appearance, that shows hints of stars still forming within it.

In this row, the PBNS team reached out to the researchers from IIA including – Jyoti Yadav, Mousumi Das and Sudhanshu Barway to understand and unravel the mystery of the newly-found galaxy.
