Possibility Of Alien Life In An Exoplanet?
Last week two teams independently reported finding water for the first time in the atmosphere of an exoplanet orbiting within the habitable zone of a distant star. The exoplanet is about 110 light-years away.
The finding makes the world - which is called K2-18b - a plausible candidate in the search for alien life.
Prof Giovanna Tinetti of University College London (UCL), described the discovery as "mind blowing", claiming;
"This is the first time that we have detected water on a planet in the habitable zone around a star where the temperature is potentially compatible with the presence of life."
So far only K2-18b revealed the molecular signature of water, which is a vital ingredient for life on Earth.
Dr Angelos Tsiaras, a member of the UCL team, said that finding water in the atmosphere of a "potentially habitable exoplanet was incredibly exciting".
Other astronomers, however, dispute the claim that the planet is potentially habitable.
