A team of Indian astronomers has found tell-tale evidence of a supernova explosion in a star-forming region called G351.7–1.2.

  • When a star reaches the end of its life cycle, it bursts, throwing up vast amounts of gas and particles at a very high speed. This explosion is called a supernova and it is a phenomenon that has fascinated scientists for centuries.
    • The term supernova was coined by European astronomer Tycho Brahe. ‘Nova’ is the Latin word for stellar explosion or rather, the spectacular death of a star.
  • The outer layer of the dead star is the first to be ripped off by the blast whereas the inner core turns into an exotic stellar object such as a pulsar, a black hole or a neutron star.

  • Scientists from Indian Institute of Space science and Technology (IIST) Thiruvananthapuram, Indian Institute of Science (IISc), Bengaluru and National Centre of Radio Astrophysics (NCRA), Pune probed the supernova the star-forming region using the Giant Metrewave Radio Telescope (GMRT).
  • The evidence is in the form of a high-velocity jet of atomic hydrogen.
    • The research team found that the jet was racing at the speed of 50 kilometers per second in the direction of the Scorpius constellation.
    • The blast extended up to 20 light years. Technically, massive stars with a mass more than 8-10 times that of our Sun result in supernova explosions.
