Once it was thought that the quantum Hall effect is experienced in materials under the influence of external magnetic fields, albeit Princeton University researchers revealed that it may also be experienced in bulk bismuth-antimony crystal without any interference from magnetic fields. The discovery could possibly le... |

Supermassive black holes are mostly found in galactic nuclei, ejecting matter in the form of particle jets at relativistic speeds during the 'feeding' process. According to theory, these particle jets are accelerated to these speeds by tightly-twisted magnetic fields generated in the close proximity of the ... |

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... |

The solar wind originates from the Sun of course, everybody knows that, but not many can explain how solar wind is actually generated, at least not in an accurate manner. Yesterday, a team of researchers from the University College London's Mullard Space Science Laboratory, led by professor Loise Harra, presente... |

It is well known that the atmosphere of the Sun is extremely dynamic, violent and excessively hot, ejecting massive quantities of matter into the surrounding space, basically every minute. But what drives and, more important, how these processes are driven remain mostly a mystery. Current and past observations with J... |

Most of us will probably never understand the true power of the Sun. Three thousand degrees Celsius or three million degrees do not make any difference to the average person, because one could never experience temperatures of this magnitude. And even if s/he experienced, s/he would never share his experience with any... |

Jupiter and Earth, two extremely different planets. One has a solid surface, the other has no surface at all; one is a rocky planet, the other, a massive gas giant, and so on. However, this doesn't mean that the two are totally different from one another. It looks like Jupiter and the Earth share one key feature... |

Have you ever noticed how both Mars and Venus are ranked as planets rather similar to Earth, but never to each other? The ESA believes it's about time it put an end to this situation and gave the task to both the Mars Express and the Venus Express, to conduct simultaneous probing investigations to establish whet... |

What better evidence for the coming of spring than the appearance of the aurora borealis, or most commonly known as the northern lights? Well, at least astrologically speaking, in the context of ever wobbling clime. For some unknown reason, it seems that the aurora borealis phenomenon takes place only during the spri... |

Following the steps of their fellow colleagues form the European Space Agency, NASA also has in plan to implement a program to predict the space weather determined by the activity of the closest star to Earth - the Sun. Lying just over 150 million kilometer from Earth, the Sun, with a diameter about 100 times that of... |

It has been long predicted that solar wind interactions would be able to generate massive amounts of X-ray radiation, however until now astronomers haven't been able to detect such emissions. Now, they have revealed what seems to be a large X-ray emission coming from the Eta Carinae binary system, determined by ... |

It's no secret now. Planets, stars may vary their magnetic fields so severely that could eventually reverse poles. Magnetic north becomes south and vice versa. Geologic evidences strongly suggest that even our planet could have reversed its poles a number of times in the past. The Sun's magnetic field orien... |

Earth, like all planets in the solar system, has an inner most core, in the shape of a sphere measuring about 1,200 kilometers, consisting of a solid mass of iron, responsible for generating our planet's powerful magnetic field. Nonetheless, while implying measurements of its structure with the help of seismic w... |

It is a well known fact that Saturn's ring E is interacting with the moon Enceladus, and might have been created by drawing material ejected through cryo-volcanism phenomenons taking place of the surface of the moon. However, new observations conducted by NASA's Cassini orbiter reveal that icy plumes of mat... |

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... |

Fifty years have passed since the launch of the third artificial satellite into space, and the first ever American satellite. Commonly known as the Explorer-1 program, the satellite 1958 Alpha liftoff from Cape Canaveral Air Force State on January 31st, 1958, thus announcing the beginning of a long series of space l... |

The most elusive constant related to the planet that has not been yet accurately determined is its spin rotation, as the gas giant is covered with a thick layer of clouds, which prevents most of the instruments aboard the Cassini probe to make detailed observations. Thus, most of the methods used to measure the spin ... |

The beautiful northern lights, or Aurora Borealis as they are commonly known, are usually triggered in the northern regions of the Earth, as electrically charged particles originating in the solar winds are captured by the planet's magnetic field and drawn towards the general regions of the poles. These electric... |

The new developed material is known from previous experiments, but it has not been very effective; however, it has been discovered that porous structures inside the material greatly amplifies the shape changing effect, which could probably be used to construct new precision valves out of a cheap, lightweight material... |

The solar wind represents an emission from the Sun in the form of electrically charged particles, mostly hydrogen, which fills the void space all around the star. Scientists say that these deadly waves of radiation blowing through the whole solar system at speeds as high as 1.6 million kilometers per hour are trigger... |
