In a groundbreaking new study that may change the way radio signals are bounced around the world in communications networks, experts managed to create an artificial ionosphere patch in the sky, by shooting powerful radio waves into the air. The “original” ionosphere is the uppermost portion of the Earth&#... |

Established astronomical knowledge had it until recently that the number of sunspots on the surface of the Sun was a clear indicator of the intensity of solar winds, and therefore of the dangers that were in store for the Earth. Solar winds are known to be extremely disruptive towards our electrical systems. They can... |

Experts at the University of California in Los Angeles (UCLA) have recently uncovered a previously unknown mode of energy transfer in the planet's upper atmosphere, between solar winds and the Earth's magnetosphere shield. According to the team, the find may have vast implications in the field of designing ... |

More than 400 years ago, a debate started in the scientific community, which was seeking to uncover the answer to the question “What generated our planet's magnetic field and magnetosphere?.” The latter is the only thing that prevents all life on Earth from being annihilated in an instant, due to mas... |

Solar storms are some of the most dangerous phenomena that can hit our planet, and they can cause billions of dollars in damage over the course of just a few hours. They pose significant threats to the high-tech global infrastructure, the power grids, the satellite networks, as well as to the astronauts aboard the In... |

The northern and southern polar regions of our planet are at times lit by some of the most beautiful phenomena in the world – the Aurora Borealis and Aurora Australis. These lights originate in an upper layer of the atmosphere known as the ionosphere, when charged particles originating in the Sun and transporte... |

The fall of 2008 saw the discovery of a new layer in our planet's protective shield, which was named the ”warm plasma cloak,” on account of the fact that it reminded scientists of a man riding a horse while wearing a cloak. The most interesting feature about this new layer is the fact that its tail c... |

A new research performed by a team of specialists led by Charles Chappell, research professor of physics and director of the Dyer Observatory at Vanderbilt University, collected and analyzed the data resulted from the observations of five different satellites. The data were related to the composition and behavior of ... |

The Cassini probe found in Saturn's orbit has managed to depict yet another mystery of the ringed planet. The content of the most recent images that the spacecraft sent back to the Earth have startled experts again. The photographs unveiled a mysterious phenomenon occurring at the planet's northernmost lati... |

Another idea coming from the SF culture is moving in the direction of becoming a reality: spaceship shields. However, as such, they would not protect the ships against evil alien races, but against a more common natural phenomenon. It is a known fact that space weather – the radiation coming from Sun and from ... |

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 ... |
