The Sun continues its relatively long period of inactivity, although while some claim that this lengthy phase without sunspots is somehow unusual, NASA researchers argue that the sun is in fact behaving normally and this period of calm is anything but long. "The sun is now near the low point of its 11-year activity c... |

On April 9, a coronal mass ejection weighing about a billion tons emerged from the surface of the Sun and, to the surprise of physicists, executed a cartwheel. At the same time, part of the mass of matter made a backflip in what now appears to be just a regular way for solar explosions to behave. "What a rare and exc... |

On April 25, a red dwarf star in the EV Lacertae constellation, known as Lacerta, ejected a massive solar flare equivalent to about a thousand solar flares emitted by the Sun. It was the brightest burst of light created by a normal star ever seen in the universe. The emission was first detected by NASA's Wind sa... |

The Sun's outer layer is in a constant turbulent state, creating waves all across the solar surface, making its experience a patchwork pattern of peaks and troughs. The Solar and Heliospheric Observatory has recently determined that these waves may be created in the outcome of solar flares exploding on the surfa... |

Hayabusa, meaning peregrine falcon in Japanese, is an unmanned space mission carried out by the Japan Aerospace Exploration Agency, having the task of returning dust from the near-Earth asteroid known as 25143 Itokawa, measuring about 540 meters/ 270 meters/ 210 meters. Hayabusa was launched into space on 9 May 2003;... |

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... |

Because plasma is mostly composed of charged particles, such as electrons and ions, which have a global neutral charge, it is able to generate powerful magnetic fields, a very important feature if you ask a nuclear physicist working on the design of a nuclear fusion reactor. However, all good things must also have ba... |

This is the first time when astronomers are able to view sun spots and mass ejection due to solar activity, on a star outside the solar system. Having a spin speed rotation about 66 times that of our Sun, the star named 'Speedy Mic' is located about ten million times farther from Earth, than our own star. ... |
