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... |

Currently the Sun is going through a period of low activity, with few or no sunspots appearing on its surface. So far nobody is complaining, albeit it does seem that the low activity period has extended a bit too long and has even fooled the scientists into uncertainty regarding whether or not a new solar cycle has b... |

It is most certain that Earth's clime took a severe turn towards global warming ever since the Industrial Revolution began. Greenhouse gas concentrations have been rising steadily since, but one cannot stop wondering what the Sun's part is in all this. How does the Sun itself affect the clime of our planet?... |

The Solar Dynamics Observatory is expected to become the next space device to monitor solar flares, sunspots and coronal mass ejections in order to make accurate predictions on solar weather. Recently the Solar Dynamics Observatory, or SDO for short, was lowered and attached to the propulsion module that will help it... |

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... |

The 24th Solar Cycle is believed to have begun a few weeks ago with the appearance of the first sunspot on the surface of the Sun, however the solar activity was relatively calm until now. This week, European Space Agency's Solar and Heliospheric Observatory detected a group of three sunspots which have appeared... |

JAXA launched the Hinode solar space observatory in September 2006 and is equipped with several instruments such as the solar optical telescope, an X-ray telescope and an EUV imaging spectrometer with which it can conduct investigations on the Sun's atmosphere but also on its interior, in order to establish the ... |

There have been some voices lately blaming global warming on the increased solar activity, however this claim is mostly based on pure speculation rather than scientific analysis, says a recent study verifying the role of the Sun in the current climatic changes which take place all over the world. Computer simulations... |

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... |

On December 11 last year, the SOHO spacecraft observed a small magnetic knot on the surface of the Sun. However, no visible sunspots have been detected lately, spots that are usually associated with the beginning of a new solar cycle. Although the sunspots were missing, scientists rushed to predict that the 24th sola... |

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. ... |
