Model gives clearer idea of how oxygen came to dominate Earth's atmosphere
A number of hypotheses have been used to explain how free oxygen first accumulated in Earth's atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. view more (2005-08-09)
Northern lights glimmer with unexpected trait
An international team of scientists has detected that some of the glow of Earth's aurora is polarized, an unexpected state for such emissions. view more (2008-04-28)
Potent greenhouse gas more prevalent in atmosphere than previously assumed
A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego. view more (2008-10-24)
Methane-eating microbes can use iron and manganese oxides to 'breathe'
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. view more (2009-07-10)
New CO2 data helps unlock the secrets of Antarctic formation
The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study. view more (2009-09-14)
ESA`s shortcut to a comet
Night owls across Europe, get ready. On the night of 18-19 November 2002, you may see a spectacular sky show. As tiny particles in Comet 55/P Tempel-Tuttle`s tail enter Earth`s atmosphere, they will pierce through it, heating up, and finally explode. Welcome to one of the most spectacular natural fireworks displays of the year: a meteor shower... view more... (2002-11-15)
Complex carbon picture clearer
Study shows that more plant litter resulting from higher CO2 could boost the amount of carbon released into the atmosphere. view more (2007-12-12)
NRL sensor provides critical space weather observations
Launched from Vandenberg Air Force Base, Calif., aboard an United Launch Alliance Atlas V launch vehicle, Oct. 18, 2009, the Special Sensor Ultraviolet Limb Imager (SSULI) developed by NRL's Space Science Division and Spacecraft Engineering Department offers a first of its kind technique for remote sensing of the ionosphere and thermosphere from... view more...

How the world watched Huygens
As Huygens parachuted to the surface of Titan in January 2005, a battery of telescopes around the world were watching or listening. view more (2006-07-28)
Mercury in atmosphere could be washed out more easily than earlier believed
Scientists for years have been at a loss to explain unexpectedly high levels of mercury in fish swimming the rivers and streams of areas like eastern Oregon, far away from industrial sources of mercury pollution such as coal-fired power plants. view more (2005-12-08)
Atmosphere and Oceans Finely Balanced
The atmosphere and oceans exist in a delicate state of balance according to research co-ordinated by the University of East Anglia (UEA) and published this month by the Natural Environment Research Council (NERC). view more (2002-01-24)
We Owe It All to Comets
Comets have always fascinated us. A mysterious appearance could symbolize God's displeasure or mean a sure failure in battle, at least for one side. view more (2009-04-29)
Studying rivers for clues to global carbon cycle
In the science world, in the media, and recently, in our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. Studying just how carbon cycles throughout the Earth is an enormous challenge, but one Northwestern University professor is doing his part by studying one important segment -- rivers. view more (2008-02-11)
Lands surface change on Alaska tundra creating longer, warmer summers in Arctic
A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic. view more (2005-09-23)
Hubble finds carbon dioxide on an extrasolar planet
The NASA/ESA Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. view more (2008-12-10)
NORTH ATLANTIC SLOWS DOWN THE GREENHOUSE-EFFECT
What sounds to us like bookkeeping of global change and tedious science, has a big meaning for our climate future. After all, traffic and industrial plants in Europe and North America play a particularly large role in the carbon dioxide pollution of the atmosphere and the greenhouse-effect resulting from it. The processes in the North Atlantic... view more... (1999-06-08)
Sulfate lens enhances climate warming properties of atmospheric soot
Particulate pollution thought to be holding climate change in check by reflecting sunlight instead enhances warming when combined with airborne soot, a new study has found. view more (2009-06-30)
Scientists pinpoint the 'edge of space'
Where does space begin? Scientists at the University of Calgary have created a new instrument that is able to track the transition between the relatively gentle winds of Earth's atmosphere and the more violent flows of charged particles in space - flows that can reach speeds well over 1000 km/hr. And they have accomplished this in unprecedented... view more... (2009-04-10)
Nature can help reduce greenhouse gas, but only to a point
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week's online edition of Proceedings of the National Academy of Sciences. view more (2006-04-11)
Strange molecule in the sky cleans acid rain, scientists discover
Researchers have discovered an unusual molecule that is essential to the atmosphere's ability to break down pollutants, especially the compounds that cause acid rain. view more (2008-08-13)
