Water is all around us, yet its surface layer—home to chemical reactions that shape life on Earth—is surprisingly hard to study. Experiments at SLAC's X-ray laser are bringing it into focus.

Plasma is usually introduced as the stuff of stars and fusion reactors, a searing soup of charged particles that has little ...

Far below the familiar blue of the oceans, scientists are uncovering evidence of a vast hidden reservoir of water locked inside the rocks of Earth’s mantle. Rather than a single underground sea, this ...

What are snowflakes? They are clusters of ice crystals, forming unique six-sided structures. Learn about the shape of a ...

Abstract: Total column water vapor (TCWV), retrieved from satellite remotely sensed measurements, plays a critically important role in monitoring Earth's weather and climate. The ozone monitoring ...

Astronomers are racing to analyse new Hubble Space Telescope images of interstellar comet 3I/ATLAS, an object with a highly unusual dual-tail structure and exotic chemical signatures that set it apart ...

Studying ice grains in a cryogenically cooled plasma, Caltech scientists have observed how fluffy particles defy gravity and ...

Scientists observing the interstellar comet 3I/ATLAS are reporting unprecedented methane-related activity and carbon-rich chemistry, identifying a set of prebiotic molecules never before seen in an ...
