In its third year of observations, SDO has opened up several new, unexpected doors to scientific inquiry. Over the last year scientists spent much time poring over data from comet observations. Comets that travel close to the sun – known as sun-grazers -- have long been observed as they move toward the sun, but the view was always obscured by the sun's bright light when the comets got too close. But SDO has now captured images of two comets as they passed close to the sun.
