This series of images reconstructs the geology of the region around Mars’ Mount Sharp, where NASA’s Curiosity Mars rover is exploring. The images, taken on Earth, have been altered for the illustration of how sediments can accumulate in alternating dry periods and wet periods. A dry period is shown at left, wet at center and dry again at right. Over time, sediments accumulate and are piled higher on the crater floor through the action of water. (Credit: NASA/JPL-Caltech)

The Milky Way galaxy is an outlier in an enormous, newly designated supercluster of galaxies dubbed Laniakea. The vast assemblage is about 500 million light years across and contains the mass of one quadrillion suns. The Local Supercluster, centered in Virgo, is a small part of the larger Laniakea. The looping lines represent galaxy flows toward large concentrations within the supercluster. (Credit: SDvision interactive visualization software by DP at CEA/Saclay, France; additions by Bob King)
