- Researchers have found both water and temperatures on K2-18b, being the only exoplanet having such components.
- The exoplanet is a planet orbiting a distant star outside our solar system.
- K2-18b is eight times the mass of Earth and about 110 light-years from the Earth in the Leo constellation.
- The team used the Hubble Space Telescope and developed open-source algorithms to analyse the starlight filtered through K2-18b's atmosphere.
- K2-18b is a cool exoplanet and receives only 5 per cent more radiation than the Earth.
- This planet is about the same temperature as Earth, but researchers are not confirmed that it is habitable or not.
