On March 17, 2011 (March 18, 2011, UTC), MESSENGER became the first spacecraft to orbit the planet Mercury. Last Update: 24 Mar 2011 (PWD) Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington
Hollows on Mercury: NASA's MESSENGER spacecraft discovered strange hollows on the surface of Mercury. Images taken from orbit reveal thousands of peculiar depressions at a variety of longitudes and latitudes, ranging in size from 60 feet to over a mile across and 60 to 120 feet deep.

Candy Stripes Date: 5 Apr 2007 This strongly enhanced false color view is a departure from the familiar bluish north and golden south seen in natural color Cassini spacecraft images, but the contrast between regions north and south of the ring shadows is here more readily apparent.
Cassini Spies Bright Venus from Saturn Orbit. Date: 4 Mar 2013 Peering over the shoulder of giant Saturn, through its rings, and across interplanetary space, NASA's Cassini spacecraft spies the bright, cloudy terrestrial planet, Venus. The vast distance from Saturn means that Venus only shows up as a white dot, just above and to the right of the image center.
Neon Saturn Date: 24 Feb 2007 Flying over the unlit side of Saturn's rings, the Cassini spacecraft captures Saturn's glow, represented in brilliant shades of electric blue, sapphire and mint green, while the planet's shadow casts a wide net on the rings.
Blinding Saturn Date: 19 Jan 2007 Surely one of the most gorgeous sights the solar system has to offer, Saturn sits enveloped by the full splendor of its stately rings. Taking in the rings in their entirety was the focus of this particular imaging sequence. Therefore, the camera exposure times were just right to capture the dark-side of its rings, but longer than that required to properly expose the globe of sunlit Saturn. Consequently, the sunlit half of the planet is overexposed.
Morning Star Date: 4 Mar 2013 Dawn on Saturn is greeted across the vastness of interplanetary space by the morning star, Venus, in this image from NASA's Cassini spacecraft. Venus appears just off the edge of the planet, in the upper part of the image, directly above the white streak of Saturn's G ring. Lower down, Saturn's E ring makes an appearance, looking blue thanks to the scattering properties of the dust that comprises the ring. A bright spot near the E ring is a distant star.
