This celestial firestorm is the blazing wreckage of a collision between two spiral galaxies NGC 4038 and NGC 4039, which are located about 62 million light-years from Earth. The two galaxies, whose bright yellow cores appear to the lower left and upper right of center, began their fateful confrontation a few hundred million years ago. The pair is nicknamed the Antennae Galaxies because of two long streamers of stars, gas, and dust that extend from the crash site. Wide-field images reveal the elongated ‘antennae’ formed during the initial impact, but this Hubble image concentrates on the heart of the galactic collision. Image credit: NASA / ESA / B. Whitmore, STScI.

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.
