"Look" sunspots.

<P> Technology Channel (http://tech./) news: the sun shining in this world may be nothing new, but the sun's surface there. .A "look" sharp telescope found around sunspots tightly around the plexiform peculiar low-temperature plasma zone, just like the sperm gathered around the egg. .Certainly limit the field of gas with these dark, but physicists have yet to understand the details. .</ P> <P> sunspots are those that are often bigger than the Earth's magnetic plaque instability. .The reason why these spots look darker is because they are other than the sun's surface temperature is 6000 ℃ regional low 2000 ℃. .The dark center of the sunspots (called the "Shadow"), the direction of the magnetic field along the vertical surface of the sun break through. .The level of magnetic field lines stretched around the penumbra (the same as a bunch of hot comb complex filaments.) .Previous photo can show small images to 150 km wide, but is not enough physicists to explain the emergence of the penumbra. .</ P> <P> Now, the clearest ever taken pictures of the resolution has increased to 90 km. .May this year, Stockholm, Sweden Institute of Physics, Sun City, Sun physicist Gran Scharmer and his colleagues started running in the Canary Islands, the world's second largest telescope. .Side of the deformable mirror next to the plane diameter of 1 meter telescope, able to eliminate image blurring caused by air flow. .November 14 "Nature" magazine published a photograph of the telescope by the amazing photos. .Image display, in the sunspot penumbra in the air swaying with bright, dark nucleus were wrapped in air center. .Dark nucleus can exist for 1 hour or longer, indicating that they are by the magnetic field maintained by the convection. .Scharmer said: "The first time I saw these small structures, so we see the fundamental physical mechanism of the solar magnetic field studies of hope." </ P> <P> Rochester, New York University, this solar physicist John Thomas .agreed, noting that the images of sunspots toward the establishment of more meaningful models taken a dramatic step. .He said that such a model needs to be on the gas velocity and the penumbral magnetic field intensity and inclination have the exact understanding - Swedish research team hope that next year to obtain the data. .It has been in the sun on the application of an improved model. .Thomas added: "In the more distant astrophysical object of study, the flow and interaction between the magnetic field is very common, but we can not study them. Sunspots compared to test our theory on this interaction provides .the basis of proof. "</ P> </ p>.
