    Spider Crater in Caloris Basin on the planet Mercury. NASA's Messenger probe took the picture of this dramatic impact crater. It looks a bit like a spider waiting in the middle of its web. Mona Evans, "Cosmic Halloween Tour" http://www.bellaonline.com/articles/art52161.asp

Venus is the most Earth-like planet in the solar system (it’s similar in size, mass, and composition); however, it is terribly unEarth-like. Similar to Earth, Venus has an atmosphere that envelops the planet. However, this is a extremely dense atmosphere that is full of greenhouse gasses. In fact, the atmosphere is so thick that is causes the surface temperatures on the planet to exceed 870 °F (465 °C), which, by the way, is hot enough to melt lead.

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.

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.

Double Ring Crater - Date: 14 Jan 2008 MESSENGER's Narrow Angle Camera (NAC) on the Mercury Dual Imaging System (MDIS) during the spacecraft's flyby of Mercury on 14 January 2008. The scene is part of a mosaic that covers a portion of the hemisphere not viewed by Mariner 10 during any of its three flybys (1974-1975). The surface of Mercury is revealed at a resolution of about 250 m/pixel (about 820 feet/pixel).

This well composed sequence captures the rising Moon and Mercury above the city lights of Brisbane in Queensland, Australia. A stack of digital images, it consists of an exposure made every 3 minutes beginning at 4:15 am local time on April 19. Mercury's track is at the far right, separated from the Moon's path by about 8 degrees.
