This is the first time when an electrical soliton wave was found in space and measured by the Cluster mission. The so-called soliton waves are a special type of wave which travel great distances without changing shape. The term soliton wave was first coined by John Scott Russell in 1834, while observing that at the b... |

On Earth, we depend on the behavior of electrons every day; we can do nothing without the help of electricity. But in space, electrons are no good for us. Powerful electromagnetic pulses can knock a computer out in an instant if not protected, not to mention of radiation poisoning caused by electrons speeding at velo... |

Our planet's magnetic field is strong enough to protect the surface from deadly radiation coming from the Sun, and, without it, the Earth would probably be pretty much dead. The Earth is being daily bombarded with massive amounts of solar wind, still Mercury receives even more radiation considering the fact that... |

The phenomenon takes place when electrons interacting with the Earth's magnetosphere go through a so-called magnetic explosion that occurs while the solar flares resulted from the Sun's activity and 'substorms' in the magnetosphere. The magnetosphere represents surrounding magnetic deflecting shie... |

A truly rare opportunity presented itself to astronomers, allowing the conjunction of ground-based instrumentation and a dozen satellites in order to explain the mysterious phenomenon of "killer" electrons.They are an occurrence in space above Earth, where plasma that is constantly ejected from the Sun's upper ... |

The aurora is a bright glow observed in the night sky, usually in the polar areas of Earth, as if the sun were rising from an unusual direction. In northern latitudes, it is known as the aurora borealis, named after the Roman goddess of the dawn, Aurora, and the Greek name for north wind, Boreas. Its southern counter... |

Talking about being in the right place at the right time, this is exactly what allowed ESA's Cluster spacecraft to make a startling discovery. The Cluster mission is an European Space Agency (ESA) unmanned space mission mission to study the Earth's magnetosphere using four identical spacecraft flying in a ... |

In physics, magnetism is one of the phenomena by which materials exert an attractive or repulsive force on other materials. Some well known materials that exhibit easily detectable magnetic properties are nickel, iron, some steels and the mineral magnetite. However, all materials are influenced to greater or lesser ... |
