Amazon fires 'quicken Andean glacier melt'

Fires in the Amazon rainforest are likely to increase the rate of melting of Andean glaciers, potentially disrupting water supply for tens of millions of people, scientists said on Thursday.

Rosetta unravels formation of sunrise jets

The atmosphere of Rosetta's comet 67P/Churyumov-Gerasimenko is far from homogeneous. In addition to sudden outbursts of gas and dust, daily recurring phenomena at sunrise can be observed. In these, evaporating gas and entrained ...

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 ...

US and Mexican astronomers develop new model of star formation

(Phys.org) —Astronomers working to estimate the rate of star formation inside murky distant galaxies, those shrouded in dust clouds that make it very difficult to study them, have published data from a brand new instrument, ...

Shocks in the Cygnus Loop supernovae remnant

(Phys.org) —Supernova remnants (SNRs) play a vital role in the lifecycle of dust in the interstellar medium. As shockwaves from supernovae sweep up interstellar material, they heat the gas and dust, and destroy a significant ...
