Cool Pictures of the Sun

From Science News:

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.

An ultimate goal of the observatory is to better predict and understand the origin of giant eruptions, called coronal mass ejections, in the sun’s outer atmosphere. When directed at Earth, these billion-ton parcels of magnetized gas can disrupt electrical power grids and satellites
