    • The discovery came to light while the researchers were investigating the chemical evolution of Sulphur dioxide (SO2) on Jupiter's moon, with Ultraviolet (UV) irradiation.
      • This revealed the traces of formation of O3 on the Callisto.

     

    • About O3 and its Significance
      • Formed of three oxygen atoms, it is an unstable compound and can be easily formed and broken down.
      • O3 layer in Stratosphere (around 15-35 km above ground) acts as invisible shield and protects from harmful UV radiation from Sun.
        • UV rays can damage DNA, trigger mutations, and cause skin cancer and cataracts in humans.
        • UV light also inhibits plant growth and has detrimental effects on various organisms.
      • However, O3 found near surface of earth is considered a pollutant which has negative effects on humans, plants and animals.
