The Sun is notorious for its 11-year cycle, but also for the fact that it has sunspots on its surface that allow astronomers to analyze its “health” and, more importantly, predict space weather. But in years such as this one, when the solar minimum is in full effect, and very few sunspots are available, e... |

According to experts at the American space agency, the concentration of cosmic-ray radiation around us has increased considerably this year, reaching its highest level in more than 50 years of observations. The level of cosmic rays has been under constant surveillance since the advent of the space age, and such a sha... |

For the first time in more than a year, the Sun's face is again spotted. Two new features have been identified on its surface, and astronomers say that this may be an indicator of the fact that the solar cycle is intensifying. Though it should theoretically be near the peak of the current cycle, the star has bee... |

According to a new report, released by a collaboration of scientists from the National Center for Atmospheric Research (NCAR), and the University of Michigan, it may be that sunspot activities are not enough to gage the intensity of solar actions, despite already-established knowledge. As an argument to prove their p... |

Over the past year, astronomers have been concerned with the decreased levels of activity recorded by our Sun, which, if past cycles are any indicator, should be teeming with activity at this time. Very few sunspots and solar flares appeared earlier this year, but the scientific community sighed in relief over the 4t... |

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... |

Sunspots have been thoroughly analyzed over the past couple of years, as a low solar cycle minimum turned the attention of the astronomical community to the Sun. But, despite trying to explain how the formations appeared, very few experts were able to come up with believable theories as to what they were made of, and... |

A few days ago, the New Jersey Institute of Technology (NJIT) just unveiled its new, remarkable solar telescope, the Big Bear Solar Observatory (BBSO), located in sunny California. With its 1.6-meter aperture, the instrument is the largest of its kind in the world, and is also one of only five such major, land-based ... |

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 ... |

Our Sun seems to have entered a very calm period, seeing how none of its usual solar flares, storms, or spots have been noticed for quite some time. While the fact that our satellites and power grids are no longer threatened by the Sun may seem like a good thing, the matter is “shady” at best, because now... |

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... |

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 ... |

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... |

Global warming is a terrible consequence of the human race continuously neglecting the planet and sucking it dry of natural resources to produce dangerous greenhouse gases. While some scientists tried to explain at least part of it as being caused by the Sun, this explanation contradicts experimental observations.Wh... |
