Here Comes the Sun

Posted April 06, 2015 12:00 AM by Engineering360 eNewsletter

The sun has been the talk of the solar system lately, showcased in a new video released by NASA and new research that reveals the source of its magnetic field. The video features five years' worth of stunning images from the successful Solar Dynamics Observatory (SDO), launched in 2010. The SDO is equipped with a variety of scientific instruments capable of imaging the extreme ultraviolet radiation from the sun's chromosphere and corona. In addition, the Institute of Astrophysics of Andalusia, using the telescopes and spectrometer on the HINODE observatory, revealed how the small supergranules at the boundaries of the sun's magnetic web contribute to the flow of the entire magnetic field.

Fascinating images. We are in a period of modern maximum of solar activity. It does have a direct relationship with any temperature anomaly we experience on Earth. More so than even the atmospheric gas relationship.

".. reveals the source of its magnetic field"

Beautiful images but they don't tell us the Sun's source of electric current, which is obviously required to sustain ANY magnetic field!
