Yesterday's Astronomy Picture of the Day © NASA: AR2835: Islands in the Photosphere REMARKABLE: What is that?!?! It looks like, for me in some way, a sunflower, but not, it's a sunspot, a cooler region where can be generated solar flares and coronal mass ejections that can affect our Earth! Enjoy! Awash in a sea of incandescent plasma and anchored in strong magnetic fields, sunspots are planet-sized dark islands in the solar photosphere, the bright surface of the Sun. Found in solar active regions, sunspots look dark only because they are slightly cooler though, with temperatures of about 4,000 kelvins compared to 6,000 kelvins for the surrounding solar surface. These sunspots lie in active region AR2835. The largest active region now crossing the Sun, AR2835 is captured in this sharp telescopic close-up from July 1 in a field of view that spans about 150,000 kilometers or over ten Earth diameters. With powerful magnetic fields, solar active regions are often responsible for solar flares and coronal mass ejections, storms which affect space weather near planet Earth.
