Latest Sunspot Stories
Two large, complex sunspots are moving across the face of the sun.
New and remarkably detailed photos of the Sun have been obtained by researchers at the New Jersey Institute of Technology’s (NJIT) Big Bear Solar Observatory (BBSO) in Big Bear, California, with the New Solar Telescope (NST).
While 2013 is supposed to be the year of Solar Max, the relatively low solar activity recorded thus far has led experts to conclude that an unusual phenomenon has occurred. This most recent solar cycle has had not one but two peaks.
As magnetic fields on the sun rearrange and realign, dark spots known as sunspots can appear on its surface. Over the course of Feb. 19-20, 2013, scientists watched a giant sunspot form in under 48 hours.
The sun is revving up and preparing for a new cycle next year, reaching solar maximum during the summer and fall months of 2013.
Australians will have the privilege of witnessing a total solar eclipse about an hour after sunrise on November 14.
For over 15 years Dr Ian Johnson of Molescreen has been removing pre-cancerous sunspots from patients using Photo Dynamic Therapy.
Scientists have long suspected that the Sun's 11-year cycle influences climate of certain regions on Earth. Records of average, seasonal temperatures do not date back far enough to confirm any patterns, though.
Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
Sunspot -- A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings, and intense magnetic activity. Although they are blindingly bright, at temperatures of roughly 5000 Kelvin, the contrast with the surrounding material at some 6000 Kelvin leaves them clearly visible as dark spots. Interestingly, if they were isolated from the surrounding photosphere they would be brighter than an electric arc. History Apparent references...
