The image is a close-up of the sun as seen by NASA's Solar Dynamics Observatory. The sun appears to be a bright yellowish-green color, with a slightly darker shade of yellow on the outer edges. In the center of the image, there is a small, circular object that looks like a star or a nebula. The object is surrounded by a thin, black line that runs diagonally across the image. The background is completely black, making the sun stand out even more.
