Indian Astronomers discover the farthest star galaxy

India’s first multi-wavelength satellite “Astrosat” detected extreme Ultra Violet light from a galaxy located 9.3 billion light years away from the earth. The galaxy is called AUDFs01. Significance India was able to achieve the discovery as the background noise in the UVIT detector of the satellite is very less. It is lesser than that of Read More…

Astrosat, Chandra and Hubble jointly detect massive cosmic explosion on Proxima Centauri

India’s first dedicated space observatory AstroSat along with other space and earth-based observatories have detected a massive coronal explosion on Proxima Centauri, sun’s closest star neighbour. The explosion was detected as part of joint multi-wavelength simultaneous observational campaign undertaken by three space-based observatories, Astrosat, Chandra and Hubble Space Telescope and the ground-based High Accuracy Radial Read More…

Vampire star caught in the act by ASTROSAT

India’s first dedicated space observatory, ASTROSAT has captured the rare phenomenon of a small six-billion-year-old vampire star preying on a bigger celestial body. The vampire star phenomenon is observed when smaller star sucks material (mass and energy) out of the bigger companion star, causing its eventual death. It is also called a blue straggler as Read More…
