This mosaic of images from the Mast Camera (Mastcam) instrument on NASA’s Curiosity Mars rover shows a series of sedimentary deposits in the Glenelg area of Gale Crater, from a perspective in Yellowknife Bay looking toward west-northwest. Curiosity’s science team has estimated that the “Cumberland” rock that the rover drilled for a sample of the Sheepbed mudstone deposit (at lower left in this scene) has been exposed at the surface for only about 80 million years.

310 million light years away is spiral galaxy NGC 4921, visible from NASA’s Hubble Space Telescope. Seen in this image are, from the center, a bright nucleus, a bright central bar, a prominent ring of dark dust, blue clusters of recently formed stars, several smaller companion galaxies, unrelated galaxies in the far distant universe, and unrelated stars in our Milky Way Galaxy.
