Scientists just found something under arctic ice that raises hopes of finding extraterrestrial life
In the search for life beyond our planet, scientists have long believed that finding planets within the so-called "goldilocks" zone of their star is the key. This roughly-defined habitable zone is neither too hot nor too cold, and if life as we know it exists elsewhere in the universe, there's a good chance we'll find it on a planet in that particular area. However, a new discovery of super-salty subglacial lakes in the Canadian Arctic is giving scientists hope that some very cold planets could still harbor life.
Subglacial lakes are nothing new, and researchers know of hundreds already. However, most of the those lakes, which exist below a thick layer of ice that covers and protects them, are fresh water. On a particularly cold planet, or even some of the moons in our own Solar System, lakes like that would have little chance of existing, but a saline-saturated lake could potentially remain liquid even in the face of incredibly low temperatures.
