Changing climate: How dust changed the face of the earth

Bremerhaven/Germany, 24 January 2014. In spring 2010, the research icebreaker Polarstern returned from the South Pacific with a scientific treasure - ocean sediments from a previously almost unexplored part of the South Polar Sea.

A closer look at a supernova's super dust factory

Galaxies can be remarkably dusty places and supernovas are thought to be a primary source of that dust, especially in the early Universe. Direct evidence of a supernova's dust-making capabilities, however, has been slim and cannot account for the copious amount of dust detected in young, distant galaxies.

Curiosity sweeps rock clean for test

Another crucial instrument on the Curiosity Mars rover has had its  first test: the Dust Removal Tool, used to sweep dust from the rover's target rocks.

Microbes piggy-back on dust clouds

A new study has found that many microbes are able to cross the Pacific Ocean on dust plumes.

Spiral found round dying star

A completely unexpected spiral structure observed around an ancient star could offer a glimpse of what our own sun has in store.

Just how poisonous is the moon?

The moon could be a highly toxic place, say scientists, warning of cancer and breathing problems even when astronauts remain in their space suits.

Trillions of comets collide around Fomalhaut

A ring of dust around the nearby star Fomalhaut is created by the collision of thousands of comets every day.

Planets smashed to smithereens near supermassive black holes

The fat, doughnut-shaped clouds of dust that surround about half of supermassive black holes could be the remnants of planets and asteroids that have smashed into each other at incredible speeds.

Dust samples reveal asteroid's history

Samples brought back from the Itokawa asteroid indicate that it's made up of the remnants of a much larger body.

Vista telescope finds 96 star clusters obscured by Milky Way dust

An international team of astronomers has discovered 96 star clusters hidden by dust in the Milky Way galaxy.

Japan confirms Hayabusa probe contained asteroid dust

Japanese scientists say they're certain that particles captured by the Hayabusa spacecraft are indeed from the Itokawa asteroid.

Self-cleaning solar panels based on Martian mission technology

Researchers have developed a system allowing large-scale solar power installations to keep themselves clean, based on technology developed for missions to Mars.
