Mars may act as a giant planetary pump

(Phys.org) —The surface of Mars is full of activity, with dust storms, dust devils, and drifting dunes in constant motion. Scientists suspect that similarly rich activity may exist underneath the surface, even though it ...

Scientists discover stardust in Antarctic snow

A team of scientists hauled 500 kilograms of fresh snow back from Antarctica, melted it, and sifted through the particles that remained. Their analysis yielded a surprise: The snow held significant amounts of a form of iron ...

Rosetta catches dusty organics

Rosetta's dust-analysing COSIMA (COmetary Secondary Ion Mass Analyser) instrument has made the first unambiguous detection of solid organic matter in the dust particles ejected by Comet 67P/Churyumov-Gerasimenko, in the form ...

Microscopic messengers from the depths of space

(Phys.org)—In 1990, an important space probe was launched, tasked with the ambitious mission of orbiting the sun and scanning our star at all latitudes. However, the much-publicized mission was not solar research but the ...
