K2-18b Exoplanet

K2-18b Exoplanet

News: Recently, NASA's James Webb Space Telescope found tentative evidence which suggests signs of life on a
distant exoplanet, K2-18b.

• It was first discovered in 2015, more than 120 light-years from Earth, during the space agency's K2 mission.
• It is 8.6 times bigger than Earth.
• It could be a 'Hycean' world with a hydrogen-rich atmosphere and a surface covered by ocean water. Now, a new investigation with the Webb telescope has revealed traces of carbon-bearing molecules in its atmosphere, including methane and carbon dioxide.

About James Webb Telescope:
• The telescope was built in collaboration between NASA, the European Space Agency (ESA) and the Canadian Space Agency.
• It was launched in December 2021.
• It's the largest, most powerful infrared space telescope ever built.
• It will examine every phase of cosmic history, from the Big Bang to the formation of galaxies, stars, and planets to the evolution of our Solar System.
