New research suggests that the makeup of space ice might be quite a bit different than we previously believed.

Water frozen in the depths of space has long been considered a shapeless, frozen fog. For decades, scientists believed it ...

"Space ice" contains tiny crystals and is not a completely disordered material like liquid water, as previously assumed, ...

"The bonds that exist in this state are extremely short-lived: 100 times shorter than a hydrogen bond in liquid water," stresses Philipp Schienbein.

Scientists may have figured out how Mars hung onto its surface liquid water in its ancient history via alternating periods of hot and cold. But what would the impact have been on habitability?

Quantum secret of hydrogen bonds in liquid water revealed for the first time Decoding the H-bond network in water molecules has never been so easy, thanks to this new spectroscopy method.

Heavy water contains more deuterium than hydrogen atoms, making it so that the ice in your drink is heavier than the water, preventing your ice from floating.

Two hydrogen atoms bond to form hydrogen gas (H 2) and two oxygen atoms bond to form oxygen gas (O 2). Note: It is true that in the electrolysis of water, oxygen and hydrogen atoms from water ...

Why does ice float in water, instead of sinking to the bottom? It has to do with water's density and molecular structure.

Clathrate structures are sustained by a host lattice formed by hydrogen-bonding water molecules, which encapsulates guest molecules. Up to now, all water molecules in the host lattice are considered ...
