Left: a ground-based view of the Milky Way’s central bulge; giant dust clouds block most of the starlight coming from the galactic center. The Hubble Space Telescope, however, peered through a region (marked by the arrow) called the Sagittarius Window, which offers a keyhole view into the galaxy’s hub. Upper right: this is a small section of Hubble’s view of the dense collection of stars crammed together in the galactic bulge. Lower right: a sample of 4 out of the 70 brightest white dwarfs spied by Hubble in the Milky Way Galaxy’s central bulge. The numbers in the inset images correspond to the stars’ location in the larger Hubble view. Image credit: NASA / ESA / A. Calamida & K. Sahu, STScI / SWEEPS Science Team / A. Fujii.

This composite image is based on observations from New Horizons’ Ralph/LEISA instrument made on July 14, when the spacecraft was 50,000 miles (81,000 km) from Charon. The data were downlinked October 1 - 4 and processed into a map of Charon’s 2.2 micron ammonia-ice absorption band (green color). Panchromatic images from New Horizons’ Long Range Reconnaissance Imager used as the background in this composite were taken on July 14 and downlinked October 5 – 6.

This mini-panorama was taken by NASA’s Spirit rover on August 23, 2005, just as the rover finally completed its intrepid climb up Husband Hill. The summit appears to be a windswept plateau of scattered rocks, little sand dunes and small exposures of outcrop. The approximate true-color view spans about 90 degrees and consists of images obtained by the rover’s panoramic camera during 18 individual pointings. Image credit: NASA / JPL-Caltech / Cornell.

$Cassini captured this image of Enceladus as it neared the moon for its closest-ever dive past the moon’s active south polar region. The image was taken in visible light with the spacecraft’s narrow-angle camera on October 28, 2015. The image shows heavily cratered northern latitudes at top, transitioning to fractured, wrinkled terrain in the middle and southern latitudes. The wavy boundary of the moon's active south polar region is visible at bottom, where it disappears into wintry darkness. This view looks towards the Saturn-facing side of Enceladus. The image was taken at a distance of approximately 60,000 miles (96,000 km) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 45 degrees.
