The huge ball of fire that gives us our daily heat and allows for life to form on the planet is the last place in the solar system where someone would expect to find rain, yet a form of it does indeed occur. Now, astronomers believe that this may help explain why the temperature in the corona, the outer atmospheric l... |

According to a new report released by NASA solar physicists and experts at the Goddard Space Flight Center, in Greenbelt, Maryland, it would appear that solar nanoflares, much smaller than the ones that can wreak havoc back on Earth, are responsible for the million-degree temperatures recorded in the thin, translucen... |

Well, sending a probe into the Sun wouldn't do much good would it, considering that the spacecraft will be totally destroyed by the dreaded heat radiating from the star? However, the Solar Probe will be the closest spacecraft ever sent to the Sun and its orbit will eventually pass through the star's outer a... |

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... |

Solar tsunamis were first discovered by ESA's Solar and Heliospheric Observatory during the late 1990s, when the spacecraft was launched. Solar tsunamis are in fact solar filaments which sweep across the surface of the Sun in a tsunami-like fashion, releasing great quantities of energy in very short periods of t... |

While being the most massive object in the solar system, the Sun may also hide one of the biggest mysteries in the solar system. The Sun is an average-sized main sequence star about 5 billion years old, currently in its mid-life, with a surface temperature approximated at about 6,000 degrees Celsius. Much of the ligh... |

For the first time, physicists have been able to make a link between the magnetic waves on the Sun's surface and its increased atmospheric temperature. The so-called Alfven waves are capable of determining massive differences in temperature between the surface and the corona, some exceeding a ratio of one hundre... |
