Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers at Penn State.
Generating, sustaining electrical currents with unique properties for information processing closer to reality
Spintronics is a form of signal processing similar to that used in traditional electronics, but it takes advantage of a property of electrons known as spin. Spin is often visualized as an arrow about which the electron rotates, ...
Opportunity, NASA's other Mars rover, has tooled around the red planet for so long it's easy to forget it's still alive.
Since captivating the world with its acrobatic landing, the Mars rover Curiosity has fallen into a rhythm: Drive, snap pictures, zap at boulders, scoop up dirt. Repeat.
A recent image acquired by NASA's MESSENGER spacecraft shows the interior of Eminescu, a youngish 130-km (80 mile) wide crater just north of Mercury's equator. Eminescu made science headlines last year with MESSENGER's discovery ...
(AP)—Sea Launch AG says it has placed a communication satellite into orbit for global provider Eutelsat.
During the space age, 1961 was a special year: the Russian cosmonaut Yuri Gagarin became the first man to orbit Earth, while the American astronomer Frank Drake developed the now famous Drake Equation. This equation estimates ...
A changing climate could have a drastic impact on fish populations in the tropics, but according to new research it's likely to boost stocks in some cooler waters.
Picture two charged particles in a vacuum. Thanks to laws of elementary electrostatics, we can easily calculate the force these particles exert upon one another, and therefore predict their movements.
