New Delhi, (PTI) New research shows that a lower amount of the carbon dioxide gas in a planet’s atmosphere compared to that of its neighbours could hint the presence of liquid water on that planet.
Researchers said that the drop in the carbon dioxide levels relative to the neighbouring planets implied a possible absorption of the gas by an ocean or isolation by biomass on a planetary scale.
While multiple studies have made attempts to identify planets lying in the habitable zones of the stars they orbit, the researchers said that until now there was no way of knowing whether they truly have liquid water.
