Latest Sunspot Stories
Scientists are determining the properties of materials inside the sun in order to prevent solar damage to high tech systems.
Why sunspots are a strong source of radio emissions and what information those emissions carry will be the focus of an invited talk by NJIT Research Professor Jeongwoo Lee tomorrow at the International Astronomical Union Symposium on the Physics of Sun and Star Spots in Ventura, CA.
NJIT Distinguished Professor Philip R Goode and the Big Bear Solar Observatory (BBSO) team have achieved "first light" using a deformable mirror in what is called adaptive optics at Big Bear Solar Observatory (BBSO).
After the most profound lull in solar activity for nearly a century, the Sun is finally coming back to life.
Scientists are learning to predict giant solar storms that could, at any time, hit the Earth and produce cascading catastrophes.
The sun is in the pits of the deepest solar minimum in nearly a century. Weeks and sometimes whole months go by without even a single tiny sunspot. The quiet has dragged out for more than two years, prompting some observers to wonder, are sunspots disappearing?
Four hundred years ago on this day, Italian astronomer and philosopher Galilei Galileo unveiled a device that would become a timeless symbol of scientific discovery â€“ the telescope.

In a breakthrough that will help scientists unlock mysteries of the sun and its impacts on Earth, scientists have created the first-ever comprehensive computer model of sunspots.
An international panel of experts led by NOAA and sponsored by NASA has released a new prediction for the next solar cycle.
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...
