Pluto may have been downsized in 2006, but it's still living large, moon wise: A fourth moon has been discovered orbiting the dwarf planet.
Croatian software developer and amateur image processor Gordan Ugarković takes images from NASA's unmanned space probes released to the Planetary Data System, splices them together and tweaks the colors, sometimes combining higher resolution black and white images with color images, sometimes recreating what the object would look like in natural color (ie, in visible wavelengths, from images taken in multiple wavelengths), sometimes heightening the contrast to bring out detail.

From Earth to the Solar System (FETTSS) is a collection of images curated by NASA that portray an attempt to understand the origin and evolution of the solar system, by looking to the skies and investigating extreme situations on earth, like high-altitude lakes and an acidic river. [more inside]
Tour the solar system from a browser window. "Eyes on the Solar System", currently in beta, from JPL and Caltech. Yes, you have to allow a 3rd party plugin. Sorry about that. Zoom in to earth, and the sunrise line is accurate for the current time. Zoom to asteroids, satellites, or planets. Rewind time to watch Voyager go home.
The Voyager I spacecraft, 33 years into its mission, "has outrun the solar wind" and is exiting the solar system. This nice article explains what this means, and has a bunch of wonderful details and interviews with the original mission scientists. [more inside]
From grainy stills to gorgeous high-resolution portraits, from intimate pairings to stark contrasts, and from old standbys to little-known surprises, The Planetary Society's Earth galleries offer a rich collection of stunning photography and video footage of our world as seen from both planetary spacecraft and geostationary satellites. It is a vista that has inspired many a deep thought in the lucky few that have seen it firsthand [previously]. Oh, and the rest of the Solar System is pretty neat, too.
NASA proposes using a Stirling cooler (essentially a Stirling engine in reverse) to keep a probe cool on the surface of Venus, which has had a tendency to melt or smash previous probes. The cooler would maintain a 25cm sphere within the probe at 200°C -- 100°C above the boiling point of water but sufficiently cool for a high-temperature microcontroller to operate. The waste heat radiators on the exterior of the sphere would reach the temperature of 500°C, 40°C above the the normal Venusian surface temperature.
The New Horizons spacecraft will be the first man-made object to visit our controversial sibling planet. An Atlas V will be used to launch the craft to the fastest speed that man has ever hurled an object to the heavens. Due to this and the small size of Pluto, the probe will only be capable of one flyby. Today is the first day in the launch window that the rocket is hoped to be launched.
Cassini Flies by Tethys and Hyperion, and the photos so far have been awesome and weird. I especially want to point out this fascinating view, which, if you look at it closely, reveals what appears to be a string of small impact craters, in a straight line over older terrain. What kind of meteor impact could have produced such an excellent formation of craters? Hyperion photos are coming. (Kokogiak's got backup in case the JRUNS strike.)
An unusual solar object is the subject of a NASA news conference on Monday. The mothership? Or a 10th planet? Thanks to MemeFirst. (Related reading: Is Pluto really a planet?)
Pioneer 10 space probe finally packs it in for good. So long, little fella...
NASA finds gravitational 'space freeway' that runs through solar system... Vorgon jokes aside, this could seriously reduce the amount of energy it takes to move around the solar system. [this is good]
Solar System Akin to Earth's Is Discovered Any minute now, I imagine somebody at a listening station on a smaller, bluer planet a few in from this one making a minute adjustment to their equipment and promptly spraying warm stimulant-laced beverage over their console...
The Solar System Simulator 'is designed to simulate - as realistically as possible - what one would actually see from any point in the Solar System. The software looks up the positions of the Sun, planets and satellites from ephemeris files developed here at JPL, as well as star positions and colors from a variety of stellar databasees, and uses special-purpose renderers to draw a color scene. Texture maps for each of the planets and physical models for planetary rings have been derived (in most cases) from scientific data collected by various JPL spacecraft.' Far too complicated for me to even begin to understand, still I've always wondered what Saturn looks like from Triton.
