UBC researchers part of Planck satellite team that uncovers secrets of the universe
University of British Columbia researchers are part of European Space Agency’s Plank satellite mission that is revealing thousands of “exotic” astronomical objects, including extremely cold dust clouds, galaxies with powerful nuclei, and giant clust…
Planck unveils wonders of the Universe
The first scientific results from Europe’s Planck spacecraft featuring the coldest objects in the Universe have today been released.
Astronomers at The University of Manchester’s Jodrell Bank Observatory played a key role in the worldwide teams se…
Broken glass yields clues to climate change
Clues to future climate may be found in the way an ordinary drinking glass shatters.
Results of a study published this week in the journal Proceedings of the National Academy of Sciences find that microscopic particles of dust can break apart …
Broken glass yields clues to climate change
BOULDER–Clues to future climate may be found in the way that an ordinary drinking glass shatters.
A study appearing this week in Proceedings of the National Academy of Sciences finds that microscopic particles of dust, emitted into the atmo…
Making stars: Studies show how cosmic dust and gas shape galaxy evolution
Astronomers find cosmic dust annoying when it blocks their view of the heavens, but without it the universe would be devoid of stars. Cosmic dust is the indispensable ingredient for making stars and for understanding how primordial diffuse gas…
Did Earth encounter pieces of an alien visitor last night?
Did Earth encounter pieces of an alien visitor last night? Apparently so! It appears tiny pieces of Comet Hartley 2 may have presented a spectacular and startling sky show across the country yesterday. NASA meteor experts had predicted it was a …
Windborne dust on high peaks dampens Colorado River runoff
On spring winds, something wicked this way comes–at least for the mountains of the Colorado River Basin and their ecosystems, and for people who depend on snowmelt from these mountains as a regional source of water.
“More than 80 percent of s…
Satellite data reveal seasonal pollution changes over India
CHAMPAIGN, Ill. — Armed with a decade’s worth of satellite data, University of Illinois atmospheric scientists have documented some surprising trends in aerosol pollution concentration, distribution and composition over the Indian subcontinen…
Pulverized planet dust might lie around double stars
Tight double-star systems might not be the best places for life to spring up, according to a new study using data from NASA’s Spitzer Space Telescope. The infrared observatory spotted a surprisingly large amount of dust around three mature, close-…
Scientist sees evidence of 'onions' in space
Scientists may have peeled away another layer of mystery about materials floating in deep space. Tiny multilayered balls called “carbon onions,” produced in laboratory studies, appear to have the same light-absorption characteristics as dust particles in the regions between the stars. “It’s the strongest evidence yet that cosmic dust has a multilayered onionlike carbon structure,” said Manish Chhowalla, assistant professor of ceramic and materials engineering at Rutgers, The State University of New Jersey. Chhowalla used transmission electron microscopes to study radiation absorption of the laboratory-produced onions and found characteristics virtually identical to those reported by astrophysicists studying dust in deep space.
