Invisible gases form most organic haze in urban, rural areas
A new study involving the University of Colorado at Boulder shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world. view more (2007-07-10)
CU-Boulder study suggests air quality regulations miss key pollutants
A new study led by the University of Colorado at Boulder reveals that air quality regulations may not effectively target a large source of fine, organic particle pollutants that contribute to hazy skies and poor air quality over the Los Angeles region. view more (2008-09-25)
Early Earth haze may have spurred life, says University of Colorado study
Hazy skies on early Earth could have provided a substantial source of organic material useful for emerging life on the planet. view more (2006-11-07)
The light and dark of Venus
Venus Express has revealed a planet of extraordinarily changeable and extremely large-scale weather. Bright hazes appear in a matter of days, reaching from the south pole to the low southern latitudes and disappearing just as quickly. view more (2008-02-22)

Arctic pollution's surprising history
Scientists know that air pollution particles from mid-latitude cities migrate to the Arctic and form an ugly haze, but a new University of Utah study finds surprising evidence that polar explorers saw the same phenomenon as early as 1870. view more (2008-03-19)
Atmospheric scientists trace the human role in Indonesian forest fires
Severe fires in Indonesia - responsible for some of the worst air quality conditions worldwide - are linked not only to drought, but also to changes in land use and population density, according to a new study in Nature Geoscience led by Robert Field of the University of Toronto. view more (2009-02-23)
Next-generation adaptive optics produces sharper Jupiter images
A two-hour observation of Jupiter using an improved technique to remove atmospheric blur has produced the sharpest whole-planet picture ever taken from the ground, according to astronomers from the University of California, Berkeley, and the European Southern Observatory (ESO). view more (2008-10-03)
Marine Algae A Weapon Against Global Warming?
"Parforce" an EU-funded research project has discovered a new link between marine algae and climate change. Researchers working on the project found out that iodine vapours, released from algae or plankton, condense over oceans to form aerosols . These aerosols, which tend to counter "global warming", can have a significant impact on... view more... (2002-07-18)
Microscopic brain imaging in the palm of your hand
Researchers at Stanford University have demonstrated a promising, minimally invasive optical technique that can capture micron-scale images from deep in the brains of live subjects. view more (2005-08-25)
NASA'S Cassini spacecraft captures Saturnian moon ballet
The cold, icy orbs of the Saturn system come to life in a slew of new movie clips showing the ringed planet's moons in motion. view more (2006-06-22)
Pollutant haze heats the Arctic
Arctic climate already is known to be particularly prone to global warming caused by industrial and automotive emissions of carbon dioxide and other greenhouse gases. view more (2006-05-11)
Record air pollution above the Arctic
Last week Scientists of the Alfred Wegener Institute for Polar and Marine Research observed the highest air pollution on record since measurements began in Ny-Ã-lesund on Svalbard. Monitoring instruments displayed significantly increased aerosol concentrations compared to those generally found. view more (2006-05-11)
Hazy red sunset on extrasolar planet
A team of astronomers have used the NASA/ESA Hubble Space Telescope to detect, for the first time, strong evidence of hazes in the atmosphere of a planet orbiting a distant star. The discovery comes after extensive observations made recently with Hubble's Advanced Camera for Surveys (ACS). view more (2007-12-11)
Predicting the weather on Titan?
Using recent Cassini, Huygens and Earth-based observations, scientists have been able to create a computer model which explains the formation of several types of ethane and methane clouds on Titan. view more (2006-01-24)
Titan's icy climate mimics Earth's tropics
If space travelers ever visit Saturn's largest moon, they will find a tropical world where temperatures plunge to minus 274 degrees Fahrenheit, methane rains from the sky and dunes of ice or tar cover the planet's most arid regions. These conditions reflect a cold mirror image of Earth's tropical climate. view more (2007-10-03)
Drizzly mornings on Xanadu
Noted for its bizarre hydrocarbon lakes and frozen methane clouds, Saturn's largest moon, Titan, also appears to have widespread drizzles of methane, according to a team of astronomers at the University of California, Berkeley. view more (2007-10-12)
`Nature` highlights use of satellite imagery to study massive CO2 release in Indonesian fires
Writing in tomorrow’s issue of Nature magazine, a team of European and Indonesian scientists used satellite imagery from ESA’s ERS and NASA’s Landsat satellites to help measure the huge amounts of carbon dioxide gas released into the atmosphere by 1997-98 fires in the tropical bush of Indonesia. A series of peatland and forest... view more... (2002-11-06)
NASA launches airborne study of arctic atmosphere, air pollution
This month, NASA begins the most extensive field campaign ever to investigate the chemistry of the Arctic's lower atmosphere. The mission is poised to help scientists identify how air pollution contributes to climate changes in the Arctic. view more (2008-04-02)
