A nearby star system is helping astronomers unravel the mystery of how water appeared in our solar system billions of years ago. Scientists observed a young star, called V883 Orionis, located ...

For the first time, scientists have observed water molecules splitting in real time to form hydrogen and oxygen. And right before they split, the molecules did something completely unexpected ...

For the first time, Northwestern University scientists have watched water molecules in real-time as they prepared to give up electrons to form oxygen. In the crucial moment before producing oxygen ...

When water is in its liquid form, its molecules strike a fine balance between order and disorder. But when the molecules that form biological materials combine with water, they tip the balance toward ...

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

But now, scientists have for the first time identified water molecules on two supposedly “dry” main-belt asteroids, 7 Iris and 20 Massalia, using data from a now-retired airborne telescope.

Using data from NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), Southwest Research Institute scientists have discovered, for the first time, water molecules on the surface of an ...

That’s changed, thanks to the work of engineers at Northwestern University. Using a new method to analyze gas molecules, they were able to observe water forming at the smallest scale ever recorded.

Water molecules have been detected in asteroid samples returned to Earth, but this marks the first time that the molecules have been discovered on the surface of an asteroid in space.

Green light means “go.” That might apply to evaporating water molecules too. Visible light, especially that of a greenish hue, might spur water to evaporate, researchers report in the Nov. 7 ...
