JUNO will help in solving mysteries related to Neutrinos such as their origin, interaction with other particles, etc. 

What are Neutrinos?

  • Neutrino is a subatomic particle with mass much smaller than other elementary particles.
  • There are three types of neutrinos:  Electron, Muon, and Tauon neutrino.
    • Neutrinos change between types as they travel. This process is called neutrino oscillation.
  • Key Characteristics: 
    • It has spin of 1/2 with a net neutral charge.
    • It travels at almost the speed of light and in straight lines from their source.
    • It rarely interacts with other matter (therefore also referred to as ghost particle).
    • They are the most abundant particles that have mass in the universe.
    • The only ways they interact is through gravity and the weak force. 

JUNO’s contribution in studying Neutrinos and its significance 

  • It would be able to observe neutrinos from the sun, gaining a real-time view of solar processes.
  • It could also study neutrinos given off by the radioactive decay of uranium and thorium in the Earth to better understand mantle convection driving tectonic plates.
  • It may provide information to probe the most violent astrophysical sources like exploding stars, gamma-ray bursts, etc.

Key Neutrino Observatories

  • India-based Neutrino Observatory (INO): Jointly funded by the Department of Atomic Energy (DAE) and the Department of Science and Technology (DST).
    • Location: Bodi West hills of Theni District of Tamil Nadu.
  • IceCube Neutrino Observatory: It is the first detector of its kind, designed to observe the cosmos from deep within the South Pole ice.
  • Other: China’s TRIDENT (Tropical Deep-sea Neutrino Telescope) and US’s DUNE (Deep Underground Neutrino Experiment)

Note: Juno Mission was launched by NASA to observe Jupiter in 2011.
