Finding traces of water on a rocky planet is rare. But now astronomers from University College London say they’ve done just that, detecting water vapor in the atmosphere of K2-18b, an exoplanet twice the size of Earth, nearly nine times as massive and about 110 light-years away. Thanks to its temperature and atmosphere, experts say it’s “the best candidate for habitability that we know right now.”
Should we get our hopes up? The UCL study reinforces similar findings by University of Montreal researchers — who claim they’d actually collected the data but were beaten to publication.
