Life in extraterrestrial worlds may be more varied than on Earth



Earth is the only place in the universe where we know that life exists. But with billions of other star systems out there, it may not be the best place to live. In a new study, astronomers model the potential for life on other aquatic planets and discover some conditions that can create oceans that are as comfortable as possible to inhabit.

The model assumes that aquatic planets with a dense atmosphere, continents, and long days – slowly rotating planets that are – were the most favorable to life. These conditions stimulate the circulation of the ocean, which carries nutrients from the depths to the surface where it is accessible for biological activity.

"[The research] shows us that the conditions of some exoplanets with favorable ocean circulation patterns may be better suited to sustaining a life that is more abundant or more active than life on Earth," Stephanie Olson, a researcher at the University of Chicago who is leading the new study, in a press release

To date, more than 4,000 exoplanets and a handful of those worlds have been orbited at a safe enough distance from the host star to have liquid water on These habitable zones of the planets are in The search for extraterrestrial life in the forefront, and new research presented at the Goldschmidt Conference in Barcelona, ​​Spain on Friday, will help astronomers curb demand.

Previous studies examining extraterrestrial habitation have been largely neglected. of the oceans to regulate global climate and heat transport. Researchers have focused on this niche using a computer model to compare different combinations of climate and ocean habitats that could and exist on exoplanets in the galaxy. The study aims to look for things like upwelling, a type of ocean-driven wind-driven circulation.
