Climate Change Affecting Earth's Outermost Atmosphere
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017 view more (2006-12-12)
Learning to live with oxygen on early Earth
Washington, D.C. Scientists at the Carnegie Institution and Penn State University have discovered evidence showing that microbes adapted to living with oxygen 2.72 billion years ago, at least 300 million years before the rise of oxygen in the atmosphere. view more (2006-10-17)
Argon conclusion: Researchers reassess theories on formation of Earth's atmosphere
Geochemists at Rensselaer Polytechnic Institute are challenging commonly held ideas about how gases are expelled from the Earth. Their theory, which is described in the Sept. 20 issue of the journal Nature, could change the way scientists view the formation of Earth's atmosphere and those of our distant neighbors, Mars and Venus. view more (2007-09-20)
Moon Magic: Researchers Develop New Tool To Visualize Past, Future Lunar Eclipses
Lunar eclipses are well-documented throughout human history. The rare and breathtaking phenomena, which occur when the moon passes into the Earth's shadow and seemingly changes shape, color, or disappears from the night sky completely, caught the attention of poets, farmers, leaders, and scientists alike. view more (2009-06-09)
Where did Venus's water go?
Venus Express has made the first detection of an atmospheric loss process on Venus's day-side. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side. view more (2008-12-19)
NASA Study Links "Smog" to Arctic Warming
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic. view more (2006-03-15)
HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at Earth Systems Processes, a multidisciplinary... view more... (2001-06-21)
Mars Express mission extended
ESA's Mars Express mission has been extended by one Martian year, or about 23 months, from the beginning of December 2005. view more (2005-09-23)
Mars and Venus are surprisingly similar
Using two ESA spacecraft, planetary scientists are watching the atmospheres of Mars and Venus being stripped away into space. The simultaneous observations by Mars Express and Venus Express give scientists the data they need to investigate the evolution of the two planets' atmospheres. view more (2008-03-06)
University of Hawaii at Manoa researchers reveal ocean acidification at Station ALOHA
The burning of fossil fuels has released tremendous amounts of the greenhouse gas carbon dioxide (CO2) into the atmosphere, significantly impacting global climate. view more (2009-08-06)
Mountain winds may create atmospheric hotspots
Rapidly fluctuating wind gusts blowing over mountains and hills can create "hotspots" high in the atmosphere and significantly affect regional air temperatures. view more (2005-10-18)
The search for ET just got easier
Astronomers using the Science and Technology Facilities Council's (STFC) William Herschel Telescope (WHT) on La Palma have confirmed an effective way to search the atmospheres of planets for signs of life, vastly improving our chances of finding alien life outside our solar system. view more (2009-06-11)
Oxygen increase caused mammals to triumph, researchers say
The first, high resolution continuous record of oxygen concentration in the earth's atmosphere shows that a sharp rise in oxygen about 50 million years ago gave mammals the evolutionary boost they needed to dominate the planet. view more (2005-09-30)
Warm coronal loops offer clue to mysteriously hot solar atmosphere
Scientists at NASA reveal a new understanding of the mysterious mechanism responsible for heating the outer part of the solar atmosphere, the corona, to million degree temperatures. view more (2008-05-30)
Mars Express PFS spectrometer back at work
The Planetary Fourier Spectrometer (PFS) on board ESA's Mars Express spacecraft is now back in operation after a malfunction, reported a few months ago. view more (2005-11-03)
MIT, Harvard offer solution to Mars enigma
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate. view more (2007-12-26)
And now the weather ... on Mars
Blinding dust storms can seriously ruin your plans for a landing on Mars. ESA is adapting the global climate models that we use to forecast our weather on Earth for the turbulent conditions that Mars offers its future visitors. You could hardly call the weather on Mars pleasant, and presently it is far from predictable. As well as having an... view more... (2002-07-03)
Texas A&M prof to predict weather on Mars
Is there such a thing as "weather" on Mars? There are some doubts, considering the planet's atmosphere is only 1 percent as dense as that of the Earth. view more (2009-11-05)
Finding Twin Earths: Harder Than We Thought!
Does a twin Earth exist somewhere in our galaxy? Astronomers are getting closer and closer to finding an Earth-sized planet in an Earth-like orbit. NASA's Kepler spacecraft just launched to find such worlds. view more (2009-03-23)
Ozone levels drop when hurricanes are strengthening
Scientists are continually exploring different aspects of hurricanes to increase the understanding of how they behave. Recently, NASA-funded scientists from Florida State University looked at ozone around hurricanes and found that ozone levels drop as a hurricane is intensifying. view more (2005-06-08)
