India's Astrosat witnesses black hole birth for 500th time in space

In News 
  • India's Astrosat space telescope has witnessed the birth of a black hole for the 500th time as stars collapse onto themselves to form the mysterious object in deep space.
Black Hole 
  • A black hole is a place in space where gravity is so strong that even light cannot escape its pull.
  • According to Nasa, the gravity in black holes is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Astrosat 
  • Launched in 2015, Astrosat has been observing Gamma-Ray Bursts (GRB) that happen when a star dies.
  • These explosions are so powerful that they have been called “mini big bangs”, sending intense jets of light and high-energy radiation shooting across the universe.
  • AstroSat is India’s first multi-wavelength space telescope, which has five telescopes seeing through different wavelengths simultaneously — visible, near UV, far UV, soft X-ray and hard X-ray.
  • Onboard the AstroSat is a 38-cm wide UltraViolet Imaging Telescope (UVIT), which is capable of imaging in far and near-ultraviolet bands over a wide field of view.
  • It is a multi-institute collaborative project, involving IUCAA, ISRO, Tata Institute of Fundamental Research (Mumbai), Indian Institute of Astrophysics (Bengaluru), and Physical Research Laboratory (Ahmedabad), among others.
  • It has been studying Gamma-Ray Bursts (GRB).
