Mars may act as a giant planetary pump
Cosmic puzzle settled: Comets give us shooting stars
Suspicions that shooting stars come from comet dust, transformed into fiery streaks as they hit Earth's atmosphere, have been bolstered by Europe's Rosetta space mission, scientists reported Monday.
Study shows how planetary building blocks evolved from porous to hard objects
(Phys.org)—Thinking small has enabled an international team of scientists to gain new insight into the evolution of planetary building blocks in the early solar system.
Dust from a comet has been discovered for the first time on the Earth's surface
Very Large Telescope Interferometer detects exozodiacal light
By using the full power of the Very Large Telescope Interferometer an international team of astronomers has discovered exozodiacal light close to the habitable zones around nine nearby stars. This light is ...
Study shows most water in lunar soil generated by solar wind, not result of comet or meteorite impacts
Seven tiny grains captured by Stardust likely visitors from interstellar space
Since 2006, when NASA's Stardust spacecraft delivered its aerogel and aluminum foil dust collectors to Earth, a team of scientists has combed through the collectors in search of rare, microscopic particles ...
VLT clears up dusty mystery
A group of astronomers has been able to follow stardust being made in real time—during the aftermath of a supernova explosion. For the first time they show that these cosmic dust factories make their grains ...
Researchers image the Milky Way's magnetic fingerprint
(Phys.org) —Our Galaxy's magnetic field is revealed in a new image from ESA's Planck satellite. This image was compiled from the first all-sky observations of 'polarised' light emitted by interstellar dust ...
Dust kicked up in Asia strengthens Indian monsoon within a week
A new analysis of satellite data reveals a link between dust in North Africa and West Asia and stronger monsoons in India. The study shows that dust in the air absorbs sunlight west of India, warming the ...
Solar wind and space dust create new source of water, laboratory study suggests
Water ice is the most abundant solid material in the universe. Much of it was created as the byproduct of star formation, but not all. John Bradley of Lawrence Livermore National Laboratory and his team may ...
NASA Mars spacecraft reveals a more dynamic red planet
(Phys.org) —NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings—possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator.
Suspected dust ring in Venus's orbit confirmed
Nanodiamond production in ambient conditions opens door for flexible electronics, implants and more
Instead of having to use tons of crushing force and volcanic heat to forge diamonds, researchers at Case Western Reserve University have developed a way to cheaply make nanodiamonds on a lab bench at atmospheric ...
