OZONE ON JUPITER’S MOON CALLISTO

In a discovery, an international team of scientists, including researchers from India, has found solid evidence indicating the presence of ozone on Jupiter's moon, Callisto.

1. This discovery has important implications for understanding the composition of the Moon's atmosphere.

Callisto: Key Facts

1. Size and Location: Callisto is one of Jupiter's largest moons and the third-largest in the Solar System, after Ganymede and Titan.
2. Composition: Callisto is primarily composed of water ice, rocky materials, sulfur dioxide, and some organic compounds. This unique composition makes it a potential place for supporting life beyond Earth in the Solar System.
3. Surface Features: Callisto's cratered surface reveals a long history of impacts from asteroids and comets. Unlike some of Jupiter's other moons, such as Io and Europa, Callisto lacks significant seismic activity.

Exploring Ozone:

1. Composition: Ozone (O3) is a gas composed of three oxygen atoms. It occurs naturally in the Earth's atmosphere, both in the upper (stratosphere) and lower (troposphere) regions.
2. Formation: Stratospheric ozone forms through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2).
3. Protective Layer: The "ozone layer," located approximately 6 to 30 miles above the Earth's surface, plays a role in reducing the amount of harmful UV radiation reaching the Earth's surface, protecting life on our planet.
