This image was taken by NASA’s Solar Dynamics Observatory at 3:12 a.m. EDT on September 13, 2015. The edge of Earth, visible near the top of the frame, appears fuzzy because Earth’s atmosphere blocks different amounts of light at different altitudes. On the left, the Moon’s edge is perfectly crisp, because it has no atmosphere. This image was taken in extreme UV wavelengths of 171 angstroms. Though this light is invisible to our eyes, it is typically colorized in gold. Image credit: NASA / SDO.

NASA’s Curiosity Mars rover captured this beautiful view of nightfall on the Red Planet on April 15, 2015. The red surface coloring of Mars is due to oxidized iron. At certain times of the Martian year, great dust storms occur; the large amounts of dust in the atmosphere during these storms absorb much of the incoming radiation from the Sun; this causes large temperature inversions in the Martian atmosphere.
