  • A team of Scientists from the Inter University Centre for Astronomy and Astrophysics (IUCAA) has discovered one of the earliest galaxies called AUDFs01 using AstroSat.
  • The galaxy is located in the Hubble Extreme Deep field, 9.3 billion light-years away from Earth.
  • Hubble extreme Deep Field (XDF) is a portion of space that contains approximately 5,500 galaxies, the oldest of which are seen as they were 13.2 billion years ago
  • XDF is recorded by the Hubble Space Telescope for over 10 years.
  • The galaxy was discovered using Ultraviolet Imaging Telescope (UVIT) on Astrosat.
  • AstroSat detected Extreme Ultraviolet light from the galaxy.
  • Earlier, NASA’s Hubble Space Telescope (HST), which is significantly larger than UVIT, did not detect any UV emission from this galaxy because it is too faint.
  • AstroSat/UVIT was able to achieve this unique feat because the background noise in the UVIT detector is much less than the ones on HST.

Verifying, please be patient.
