Tonight, December 28, the charged particles released from the Sun during a solar flare that occurred on December 26 will hit Earth's magnetosphere, and most likely cause polar lights to increase in brightness. Astronomers say that the flare was strong enough to cause such an effect.

This amazing video sent back by the NASA Solar Dynamics Observatory (SDO) shows how a speeding comet slammed itself into the Sun. According to solar physicists, the ensuing blast that occurred on the other side of the star was not caused by the impact.
The collision took place over the weekend, when a sungrazer c... |

Though it's not advisable to look at the Sun with the naked eye, astronomers say that the sunspot group currently moving across the star's surface can be seen without telescopes. Dubbed AR 1302, the object started developing last week.
According to experts at NASA, this is the largest and most active su... |

As the Sun is approaching the peak of its current cycle, it is producing massive solar flares increasingly often. For the third time this year, an X-class event took place on the surface of the star. Just a few hours ahead, it was preceded by an M-class storm.
These instances of increased solar activity took plac... |

Astronomers keeping an eye on the Sun say that the 2011 summer solstice, which took place yesterday, June 21, was accompanied by a storm of activity on the surface of the Sun. The two events are unrelated, but the coincidence was more than welcomed among solar physicists.A solar flare and a coronal mass ejection mark... |

Though the Sun should theoretically enter a period of increased activity called a solar maximum, experts say that the star may in fact be getting ready to become less active over the next few years. Peak solar maximum was supposed to be achieved between 2012 and 2013. The new conclusions are based on an thorough anal... |

Solar physicists keeping tracks of phenomena taking place on the surface of the Sun say that they recently made a discovery that could make predicting space weather more reliable than ever before. The team conducting the observations says that recent studies managed to capture images of clouds of material being eject... |

According to a new research study by astrophysicists, it would appear that when the Sun experiences its most violent explosions, it does so at a massive scale, which sees the entire star trembling under the intensity of the blast. The explosions are all inter-connected through enormous magnetic threads, some of which... |

A team of investigators from the United States discovered that about 33 percent of all solar eruptions happening on the Sun are not easily detectable beforehand, and therefore can be described as sneak attacks. The research was conducted with data from the NASA STEREO spacecraft.
While in the past solar storms wer... |

A recent solar flare from our Sun has put the international astronomical community in a state of heated debate, as a team of researchers proposed that the cosmic event proves a long-since abandoned theory that CME are in fact giant ‘magnetic flux ropes.’This was first hypothesized back in 1989 by Dr James... |

As our Sun is beginning to wake up from its prolonged period of solar minimum, researchers are again starting to take interest in the possible effects that this awakening may have on our planet. Earth itself is at no risk from these outbursts of hot, ionized gas from the star, but everything that operates with electr... |

Astronomers announce the discovery of a new, active group of sunspots on the surface of our star, after a period of a couple of years in which the celestial body has been unusually quiet. The Sun usually functions in 11-year-long cycles, but it would appear that the last one has yet to pick up in speed and intensity,... |

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... |
