Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, a view similar to that which one would see from a spacecraft. The distance is 1,550 miles (2,500 km) from the surface of the planet. The mosaic is composed of 102 Viking Orbiter images of Mars. The center of the scene shows the entire Valles Marineris canyon system, over 1,240 miles (2,000 km) long and up to 5 miles (8 km) deep, extending form Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. Many huge ancient river channels begin from the chaotic terrain from north-central canyons and run north. The three Tharsis volcanoes (dark red spots), each about 15.5 miles (25 km) high, are visible to the west. South of Valles Marineris is very ancient terrain covered by many impact craters.

The CTB 1 supernova remnant resembles a ghostly bubble in this image, which combines new 1.5 GHz observations from the Very Large Array (orange, near center) with older observations from the Dominion Radio Astrophysical Observatory’s Canadian Galactic Plane Survey (1.42 GHz, magenta and yellow; 408 GHz, green) along with infrared data (blue). The VLA data clearly reveal the straight, glowing trail from PSR J0002+6216 and the curved rim of the remnant’s shell. Image credit: Jayanne English, University of Manitoba / NRAO / F.

This composite picture combines nine individual images taken with New Horizons’ Long Range Reconnaissance Imager (LORRI), each with an exposure time of 0.025 seconds, just 6 ½ minutes before the spacecraft’s closest approach to Ultima Thule. The image was taken at 12:26 a.m. EST (5:26 a.m. GMT) on January 1, 2019, when the spacecraft was 4,109 miles (6,628 km) from Ultima Thule and 4.1 billion miles (6.6 billion km) from Earth. The angle between the spacecraft, Ultima Thule and the Sun -- known as the ‘phase angle’ - was 33 degrees.
