The analytical technique of mass spectrometry allows the identification of the chemical composition of a sample or of a compound based on the mass-to-charge ratio of its charged particles (ions). This ratio of the particles is observed via passing them through the electric and magnetic fields of a mass spectrom... |

Although they are not as visible as Saturn's beautiful rings of particles, Jupiter's rings were in fact discovered in 1979 during the first Voyager mission. Until 1995, when the Galileo spacecraft entered orbit around Jupiter, scientists had in fact no image of the thin, mysterious features around our solar... |

Aurora Borealis, most commonly known as the Northern Lights, is created when cosmic rays - solar wind in special - interact with the Earth's magnetic field and the atmosphere in order to determine light emissions in the gas atoms located in the upper layers of the atmosphere. In the middle of the 20th century, R... |

Earth's powerful magnetic field is shaped by the solar wind into a tear-like elongated structure, enveloping the planet. This so called magnetotail spans well beyond the orbit of the Moon, meaning that the Moon passes through it once a month, during the full moon phase, determining lunar dust storms and electros... |

Air friction would be something to begin with; on the other hand, multiple studies conducted over decades have shown that the electrical fields generated through this process are not able to create even a spark, not to talk about an electric disruptive discharge several hundred meters long. Even if we take into consi... |

It seems that wind action alone is not enough to account for the observed effects during sandstorms, thus scientists went searching for an alternative explanation, which strangely could also lift the mystery hovering above some weird effects seen on the Red Planet. It is a well-known fact that bodies rubbing against ... |
