US spacecraft enters Mars orbit, India probe next (Update)
NASA's Maven spacecraft entered orbit around Mars for an unprecedented study of the red planet's atmosphere following a 442 million-mile (710 million-kilometer) journey that began nearly a year ago.
Study reveals California meteorite's rough and tumble journey
(Phys.org) —A meteorite that fell onto the roof of a house in Novato, California, on Oct. 17, 2012, has revealed a detailed picture of its origin and tumultuous journey through space and Earth's atmosphere. ...
Solar explosions inside a computer
Strong solar flares can bring down communications and power grids on Earth. By demonstrating how these gigantic eruptions are caused, ETH physicists are laying the foundations for future predictions.
Squeezed quantum communication
New prospects for secure data traffic: Flashes of light in particularly sensitive quantum states can be transmitted through the atmosphere.
New study shows how conversion of forests to cropland affected climate
The conversion of forests into cropland worldwide has triggered an atmospheric change that, while seldom considered in climate models, has had a net cooling effect on global temperatures, according to a new ...
New study confirms water vapor as global warming amplifier
A new study from scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science and colleagues confirms rising levels of water vapor in the upper troposphere – a key amplifier ...
MAVEN Mars spacecraft to begin orbit of Red Planet
A NASA spacecraft that aims to study the upper atmosphere of Mars and reveal how its climate changed over time is poised to begin orbiting the Red Planet on Sunday.
Scientist uncovers red planet's climate history in unique meteorite
Was Mars—now a cold, dry place—once a warm, wet planet that sustained life? And if so, how long has it been cold and dry?
NASA's Maven spacecraft reaches Mars this weekend
Mars, get ready for another visitor or two. This weekend, NASA's Maven spacecraft will reach the red planet following a 10-month journey spanning 442 million miles (711 million kilometers).
Earth organisms survive under Martian conditions
(Phys.org) —New research suggests that methanogens—among the simplest and oldest organisms on Earth—could survive on Mars.
Reducing emissions will be the primary way to fight climate change, study finds
Forget about positioning giant mirrors in space to reduce the amount of sunlight being trapped in the earth's atmosphere or seeding clouds to reduce the amount of light entering earth's atmosphere. Those approaches to climate ...
Software renders Earth's atmosphere in 3-D splendor
As an atmospheric scientist, Martin Jucker found it frustrating that the Earth's atmosphere typically appears as a consistent, two-dimensional plane when scientists visualize atmospheric data. Horizontal ...
Colliding atmospheres: Mars vs Comet Siding Spring
On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away—which would be like a comet passing about 1/3 of the distance between Earth and the Moon.
Research resolves discrepancy in Greenland temperatures during end of last ice age
A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming occurred.
