A team of researchers from several institutions in France, the U.S. and Sweden has used models of possible conditions on Mars to show that the red planet may have sported a northern ocean 3 billion years ago and that the ...
Seemingly ordinary, water has quite puzzling behavior. Why, for example, does ice float when most liquids crystallize into dense solids that sink?

(Phys.org) —A team of researchers, led by space scientist Jacqueline Faherty, has found evidence of water clouds in the atmosphere of a brown dwarf situated just 7.3 light years away. In their paper to be published in The ...
At the base of the Transantarctic Mountains lies a geological oddity. Don Juan Pond is one of the saltiest bodies of water on the planet, filled with a dense, syrupy brine rich in calcium chloride that can remain liquid to ...
