University of Cambridge-led team identifies compounds in K2-18b's atmosphere linked to life on Earth; Webb Telescope analysis marks a milestone in space observatories
Location: United Kingdom
Key Developments
- The Webb Space Telescope, launched in 2021 by NASA and ESA, was used to analyze exoplanet K2-18b's atmosphere.
- Astronomers from University of Cambridge detected chemical compounds in K2-18b's atmosphere linked to living organisms on Earth.
- K2-18b is located 124 light-years from Earth.
- This marks a significant milestone in using space telescopes for detecting potential biosignatures beyond our solar system.
