New Delhi: A team of Indian astronomers led by Dr.Kanak Saha from the Inter-University Centre for Astronomy and Astrophysics(IUCAA), Pune, have discovered one of the farthest star galaxies in the universe with the help of India’s first Multi-Wavelength Space Observatory “AstroSat”.
The Observatory detected extreme-UV light from a galaxy called AUDFs01 located 9.3 billion light-years away from Earth.
The importance and uniqueness of this original discovery can be made out from the fact that it has been reported in the leading international journal “Nature Astronomy” published from Britain. India’s AstroSat/UVIT was able to achieve this unique feat because the background noise in the UVIT detector is much less than one on the Hubble Space Telescope of US based NASA.

According to Director of Inter-University Centre for Astronomy and Astrophysics (IUCAA) Dr Somak Ray Chaudhury, this discovery is a very important clue to how the dark ages of the Universe ended and there was light in the Universe. We need to know when this started, but it has been very hard to find the earliest sources of light, he said.
Pertinent to mention that India’s first Space Observatory AstroSat, which has made this discovery, was launched by the Indian Space Research Organization (ISRO) on September 28, 2015. It was developed by a team led by Shyam Tandon, Ex Emeritus Professor, IUCAA with the full support of ISRO.
According to Professor Tandon, the excellent spatial resolution and high sensitivity was a tribute to the hard work of the UVIT core team of scientists for over a decade.
Congratulating the astronomers here on Tuesday, Union Minister of State (Independent Charge), Atomic Energy and Space, Dr Jitendra Singh said India’s space scientists had once again proved to the world that the country’s capability in space technology had risen to a “distinguished level from where our scientists are now offering cues and giving leads to the Space scientists in other parts of the world”.
