The sky on
your birthday.
“Sun Spot Hill” is copyrighted by Jordi Coy. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteOur Sun rises over Sierra del Cid in Spain, displaying several sunspots on its surface. Sunspots are cooler, darker regions caused by intense magnetic activity. The number of sunspots varies over an 11-year cycle, and this image shows a return to more activity after a period of solar minimum. The detailed foreground captures the texture of the hill.
