This image reveals something we couldn’t see otherwise without risking blindness: the surface of the Sun. A fierce burning outline, the corona, delineates the star, and a band of fire made up of countless flares and explosions animates its surface. The edges of this band look like golden fibers feathering out into the blackness of space. It’s a glorious and terrifying vision that’s actually a composite of 23 separate images taken over a year. Solar explosions can sometimes disrupt technology in space, so images like this one are key for scientists trying to understand the electromagnetic system that causes movement on the sun.
