Study shows Moon engulfed in permanent, lopsided dust cloud
The moon is engulfed in a permanent but lopsided dust cloud that increases in density when annual events like the Geminids spew shooting stars, according to a new study led by University of Colorado Boulder.
Saturn's outer ring much bigger than thought
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
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 ...
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 ...
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 ...
Potential solution to meteorite mystery: Chondrules may have formed from high-pressure collisions in early solar system
(Phys.org) —A normally staid University of Chicago scientist has stunned many of his colleagues with his radical solution to a 135-year-old mystery in cosmochemistry. "I'm a fairly sober guy. People didn't ...
New observations of a 'dust trap' around a young star solve long-standing planet formation mystery
Astronomers using the new Atacama Large Millimeter/submillimeter Array have imaged a region around a young star where dust particles can grow by clumping together. This is the first time that such a dust ...
Cirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...
Grains of sand from ancient supernova found in meteorites
(Phys.org) —It's a bit like learning the secrets of the family that lived in your house in the 1800s by examining dust particles they left behind in cracks in the floorboards.
Searching for the solar system's chemical recipe
(Phys.org)—By studying the origins of different isotope ratios among the elements that make up today's smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust, Mark Thiemens and ...
