As a landmark achievement in Space missions, Indian Astronomers have discovered one of the farthest Star galaxies in the universe – AUDFs01.
India’s first Multi-Wavelength Space Observatory “AstroSat” has detected extreme-UV light from a galaxy located 9.3 billion light-years away from Earth – called AUDFs01.
How did we manage to discover it?
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.
- Astrosat is India’s first dedicated multi-wavelength space telescope.
- AstroSat, was launched in 2015, by PSLV-C30 from Sriharikota (Andhra Pradesh).
- It is the first dedicated Indian astronomy mission aimed at studying celestial sources in X-ray, optical and UV spectral bands simultaneously.
- The minimum useful life of the AstroSat mission is expected to be 5 years.
The scientific objectives of ASTROSAT mission are:
- To understand high energy processes in binary star systems containing neutron stars and black holes
- Estimate magnetic fields of neutron stars
- Study star birth regions and high energy processes in star systems lying beyond our galaxy
- Detect new briefly bright X-ray sources in the sky
- Perform a limited deep field survey of the Universe in the Ultraviolet region
