Cluster helps to model Earth's mysterious magnetosphere

For many years, scientists have been striving to understand the constantly changing structure and behaviour of the huge magnetic bubble that surrounds our planet. One approach – pioneered by Russian scientist Nikolai Tsyganenko ...

NASA's MMS observatories stacked for testing

(Phys.org) —Engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., accomplished another first. Using a large overhead crane, they mated two Magnetospheric Multiscale, or MMS, observatories – also called mini-stacks—at ...

Researchers find planet-sized space weather explosions at Venus

Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, ...

Plasma loss mechanisms from Saturn's magnetosphere

Since the first up-close observations of Saturn, made by the Pioneer 11 probe in 1979, a great deal has been learned about the dynamics of the gas giant's magnetosphere. In-depth observations made by the Cassini orbiter, ...

ESA's Cluster satellites in closest-ever 'dance in space'

(Phys.org) —Since 2000, the four identical satellites of the Cluster quartet have been probing Earth's magnetosphere in three dimensions. This week, two of them made their closest-ever approach, just 4 km, enabling valuable ...

NASA sees another Earth-directed CME

On August 21, 2013 at 1:24 am EDT, the sun erupted with an Earth-directed coronal mass ejection, or CME, a solar phenomenon that can send billions of tons of particles into space and reach Earth one to three days later. These ...

NASA spacecraft capture an Earth directed coronal mass ejection

On August 20, 2013 at 4:24 am EDT, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon which can send billions of tons of particles into space that can reach Earth one to three days later. ...

Red dwarf stars could strip away planetary protection

(Phys.org) —Red dwarf stars are the commonest type of stars, making up about 75% of the stars in our Galaxy. They are much smaller and much less massive than our Sun and for that reason a lot dimmer. If planets are found ...
