Snow and sand erosion explained

Scientists at EPFL and SLF describe with precision how snow and sand surfaces erode when exposed to wind. Their description can contribute to better predictions of dust emissions from deserts and snow transport in Antarctica, ...

Tune your radio: Galaxies sing when forming stars

A team led from the Instituto de Astrofísica de Canarias (IAC) has found the most precise way ever to measure the rate at which stars form in galaxies using their radio emission at 1-10 Gigahertz frequency range.

Scientists sweep stodgy stature from Saturn's C ring

As a cosmic dust magnet, Saturn's C ring gives away its youth. Once thought formed in an older, primordial era, the ring may be but a mere babe – less than 100 million years old, according to Cornell-led astronomers in ...

Studies find echoes of black holes eating stars

Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects. When a star passes within a certain distance of a black hole, the ...

Image: Planck's flame-filled view of the Polaris Flare

This image from ESA's Planck satellite appears to show something quite ethereal and fantastical: a sprite-like figure emerging from scorching flames and walking towards the left of the frame, its silhouette a blaze of warm-hued ...

How atmostpheric dust affects photovoltaic output

A hazy sky and dirty cars are well-known consequences of Saharan dust carried to Europe by air currents. As part of the "PerduS" project, the German Weather Service (DWD), the Karlsruhe Institute of Technology (KIT) and meteocontrol ...

Sand dunes are important desert dust sources

Dust storms are a common occurrence in the deserts of northern China, and has accumulated to great thicknesses to form the vast Chinese loess plateau. Researchers have attempted to locate the most important sources of this ...
