Molecular dynamics model uses topological order parameter to show stratification of water molecules based on density.

Water is so common that we take it for granted. Yet water also has very strange properties compared to most other liquids. In addition to ordinary water and water vapor, or steam, there are at ...

It's made by depositing water vapor on very cold surfaces. This process happens naturally in space, Salzmann said, so low-density amorphous ice may be the most common form of ice in the universe .

Astronomers have finally uncovered water vapor in the atmosphere of a super-Earth exoplanet orbiting within the habitable zone ... But the density of K2-18 b is what really cements it as a rocky ...

The detection of water vapor in the atmosphere of K2-18b brings some clarity to this exoplanet, but like any big discovery, the data raised more questions than it answered.

Water was coming off Ceres at a rate of 6 kilograms, or about 13 pounds, per second -– and the scientists think there could be so much ice packed in the dwarf planet’s mantle that its melted ...
