This Stunning Video Shows Sun's Pulsing 'Skin' in Incredible Detail
By Elizabeth Howell a day ago
A paper based on the research was published in the journal Astronomy & Astrophysics last year, led by Jorrit Leenaarts, director of Stockholm University's Institute for Solar Physics.
A new video shows a view of the sun that's so strange you'd think it came from a science fiction horror film. The "skin" of the sun — also known as the photosphere — pulses and morphs in an active region of solar granules imaged by a Swedish telescope.
"These granules are the tops of convection cells where hot gas rises from the interior to cool, and then descends back down," NASA explained in a statement.
The image also shows a dark blemish on the sun's skin, which is a collection of sunspots. Each sunspot is a region of strong magnetic disturbance on the sun. Sometimes, the magnetic fields in these regions align and shoot off material from the sun's surface in an event known as a coronal mass ejection (CME).
