The red streaks crisscrossing the surface of Europa, one of Jupiter's moons, are striking. Scientists suspect it is a frozen mixture of water and salts, but its chemical signature is mysterious because it matches no known ...

A team of researchers at the Chinese Academy of Sciences, working with a colleague from the University of Copenhagen, has found evidence that water was present on Mars more recently than has been thought. In their paper published ...
Dark features on Mars previously considered evidence for subsurface flowing of water are interpreted by new research as granular flows, where grains of sand and dust slip downhill to make dark streaks, rather than the ground ...

(Phys.org)—The hydrophobic effect is a fundamental aspect of biochemical processes. Hydrophilic, or water-loving, solutes tend to be miscible in water, while hydrophobic, or water-fearing, solutes tend to aggregate in such ...
(Phys.org)—One of the biggest and most important findings made by NASA recently was the confirmation that liquid water currently flows on Mars. Scientists suspected this a long time ago, but really strong evidence was needed ...
New findings from NASA's Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.
