This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.

This Hubble image shows the lenticular galaxy NGC 4036. The bright star visible slightly to the right of the galactic center is not within the galaxy itself; it sits between us and NGC 4036, adding a burst of brightness to the scene. The image is a composite of separate exposures acquired by Hubble’s Advanced Camera for Surveys (ACS) instrument. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / Judy Schmidt, www.geckzilla.com.
