In this night scene from the early hours of November 14, light from a last quarter Moon illuminates clouds above the mountaintop domes of Kitt Peak National Observatory near Tucson, Arizona. Bright Jupiter is just left of the overexposed lunar disk with a streak of camera lens flare immediately to the right, but that's no fireball meteor exploding near the center of the picture.

Solar magnetism - National Geographic  A composite picture shows what the sun's atmosphere looked like on Wednesday, as seen in three different wavelengths of light.  One of three main instruments on the orbiting observatory, the AIA takes pictures of the sun in ten wavelengths every ten seconds. Overlaying several such images can show how magnetic events, such as prominence eruptions and coronal mass ejections, generate motion across the solar orb.
