- AstroSat has detected extreme-UV light from a galaxy, called AUDFs01, 9.3 billion light-years away from Earth.
- The galaxy is located in the Hubble Extreme Deep field, through AstroSat.
- This is a very important clue to how the dark ages of the universe ended and there was light in the universe.
- AstroSat is India’s first dedicated multi-wavelength space telescope. It was launched on a PSLV-XL on 28 September 2015.
It is the first dedicated Indian astronomy mission aimed at studying celestial sources in X-ray, optical and UV spectral bands simultaneously.
