Image: Snowing in space?

The flurry of what looks like snow in this video is actually a barrage of energetic particles. This is what's known as a solar radiation storm, hitting an instrument onboard ESA/NASA's Solar and Heliospheric Observatory, ...

Chemists weigh intact virus mixture with mass spectrometer

Carnegie Mellon University chemists, led by Mark Bier, have separated and weighed virus particles using mass spectrometry (MS). This is the first time that researchers successfully used matrix-assisted laser desorption ionization ...

New technology tracks tiniest pollutants in real time

Researchers may soon have a better idea of how tiny particles of pollution are formed in the atmosphere. These particles, called aerosols, or particulate matter (PM), are hazardous to human health and contribute to climate ...

Coronal mass ejections at Mars

Looking across the Mars landscape presents a bleak image: a barren, dry rocky view as far as the eye can see. But scientists think the vista might once have been quite different. It may have teemed with water and even been ...

How the sun caused an aurora this week
