Solar Image Webcam
This real-time ultraviolet image of the Sun measures a mid-temperature region of the Sun in a transition zone between the surface and the roughly 1-million-degree corona (the Sun’s atmosphere), Gurman says. Brighter and darker features are all manifestations of the Sun’s magnetic field. The brightest areas indicating strong magnetic fields.
Dark stringy areas cooler than the corona and are called filaments; when they appear outside the disk of the Sun, they’re called prominences. The fuzzy glow around the disk is relatively cool material that is ionized. Collisions of particls have stripped electrons off the atoms. Mottled areas are known as the chromospheric network, where strong magnetic fields congregate.
Bright spots in the background of space represent cosmic rays or charged particles that have been accelerated when a coronal mass ejection collides with the ambient, but ever-changing solar wind. Sun Snapshot Webcam HERE. Check out the full list of Space Webcam.
