In an experiment akin to stop-motion photography, scientists have isolated the energetic movement of an electron while “freezing” the motion of the much larger atom it orbits in a sample of liquid ...

Stellar dendrites, the snowflakes so often featured on holiday illustrations, form when water vapor combines with dust in clouds and freeze ... “The liquid first evaporates and then the vapor ...

Other researchers think that brines, which are solutions with a high concentration of salts, such as Earth's oceans, may hold the key to finding liquid water on Mars. Brines can freeze at much ...
