Two months after the launch of NASA’s Solar Dynamics Observatory, its first images are now arriving back on Earth with more detail about the sun than has ever been seen before. Some of the images from the spacecraft reveal in new clarity the material streaming outward and away from sunspots. Others show extreme close-ups of activity on the sun’s surface. The spacecraft also has made the first high-resolution measurements of solar flares in a broad range of extreme ultraviolet wavelengths.
