There’s plenty new on the sun, both inside and out, a recently launched solar observatory has discovered.
After staring at the sun for only a few weeks, NASA’s Solar Dynamics Observatory has already recorded the interplay between a small sunspot on the solar surface and disturbances high in the sun’s outer atmosphere. It has also made the first high-definition recording of a solar eruption over a broad range of ultraviolet wavelengths.
