Mysteries of space dust revealed
The first analysis of space dust collected by a special collector onboard NASA's Stardust mission and sent back to Earth for study in 2006 suggests the tiny specks open a door to studying the origins of the ...
Evidence for supernovas near Earth
Once every 50 years, more or less, a massive star explodes somewhere in the Milky Way. The resulting blast is terrifyingly powerful, pumping out more energy in a split second than the sun emits in a million ...

Europe sees five possible sites for comet landing
The European Space Agency (ESA) on Monday said it had drawn up a shortlist of five possible sites for carrying out the first-ever landing on a comet.
Electric sparks may alter evolution of lunar soil
The moon appears to be a tranquil place, but modeling done by University of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly ...
Two dynamos drive Jupiter's magnetic field
(Phys.org) —Superlatives are the trademark of the planet Jupiter. The magnetic field at the top edge of the cloud surrounding the largest member of the solar system is around ten times stronger than Earth's, ...
Follow the radio waves to exomoons, astrophysicists say
Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon. Now, physicists ...
Violent solar system history uncovered by WA meteorite
Curtin University planetary scientists have shed some light on the bombardment history of our solar system by studying a unique volcanic meteorite recovered in Western Australia.
Step closer to birth of the Sun
Researchers are a step closer to understanding the birth of the sun.
IBEX and Voyager spacecraft drive advances in outer heliosphere research
Scientists yesterday highlighted an impressive list of achievements in researching the outer heliosphere at the 40th International Committee on Space Research (COSPAR) Scientific Assembly in Moscow.
Evidence of a local hot bubble carved by a supernova
I spent this past weekend backpacking in Rocky Mountain National Park, where although the snow-swept peaks and the dangerously close wildlife were staggering, the night sky stood in triumph. Without a fire, ...
Rosetta lander will seek a close encounter with comet's 'primordial soup'
There is much excitement about Rosetta at the moment. The European Space Agency's spacecraft has already made a successful rendezvous with a comet and the images that are being transmitted back are simply ...
Dating the sun's prenatal history can help find life on other planets
Without the sun, there would be no Earth – but amazingly, we don't know the finer details about the prenatal history of our sun, where it was born and if other stars in our galaxy share a similar history.
Rosetta will teach us more about comets than we have learned in 50 years
On August 6, millions of miles away from Earth, the firing of a rocket thruster signalled the end of a decade-long journey by a European spacecraft to reach its ultimate target – a comet.
