Has a planet been found with water?
The European Space Agency’s (ESA) exoplanet-hunting Cheops satellite has found a third planet in a star system previously believed to have only two planets. The third planet, discovered in a unique photobomb, appears to contain large amounts of water clouds.
When was planet9 discovered?
Mike Brown and Konstantin Batygin, both of Caltech, announced in early 2016 that they had evidence for a Planet Nine – another major planet in our solar system – lurking somewhere in our solar system’s outer realm.

Who was the scientist who found water on a star?
The lead scientist, Prof Giovanna Tinetti of University College London (UCL), described the discovery as “mind blowing”. “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,” she said.
Which is the only exoplanet known to have water?
K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life. UCL researchers used archive data from 2016 and 2017 captured by the NASA/ESA Hubble Space Telescope and developed open-source algorithms to analyze the starlight filtered through K2-18b’s atmosphere.
Which is the only planet outside the Solar System that has water?
K2-18b, which is eight times the mass of Earth, is the only planet orbiting a star outside the solar system (or “exoplanet”) known to have both water and temperatures that could support life.
Is the water found on K2-18b habitable?
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.
