For a long time, astronomers have known that the Sun passes through 11-year activity cycles, in which periods of high and low activity can be recorded. However, up until now, there have been few cycles in which the star failed to become active when it was time to, such as it happens now. According to predictions, sin... |

An inter-agency panel of experts in the United States has calculated a prediction number of Solar Cycle 24, the 11-year time frame we are in now. This is, obviously, the 24th cycle since humans began to take notice of the repeating patterns of solar activities, and, according to estimates, it will peak in May 2013, w... |

Astronomers at NASA now bless their inspiration of sending the STEREO twin solar observatories into space, as the two spacecraft revealed only a few days ago the fact that the Sun seemed to be resuming its normal activity for this time. Last year, the star should have reached its minimum peak, and then begun to act ... |

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... |

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... |

The scientific community has been rather excited this week, as the SOHO spacecraft has captured in images what seems to be a small magnetic knot appearing on the surface of the Sun, announcing the end of the 23rd Solar Cycle, which has peaked during 2000 and 2003 with violent solar storms and material ejection. Origi... |
