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.

Explore our local chunk of space.
Here is a scale view of the Solar System, and
here one can take a quick trip around it. Use the
guidebook to plan your trip (but beware the pop-up ads). Don't forget to bring a
camera and snap some
photos.

Cartography is a skill pretty much taken for granted now, but it
wasn't always
so. Accurate maps were once prized state secrets, laborious efforts that cost a fortune and took years (or even decades) to complete.
How things have changed. (Yours now,
$110) It took almost 500 years to map North America, but it's only taken one tenth of that to map just everything else. In the last 50 years, we've been able to create acurate atlases of
two planets and
one moon (with a
second in the works). Actually,
we've done a lot more than that. We're actually running out of things to map.
Maybe Not.

Saturn's enigmatic moon
Titan holds on to its mysteries.
Radar images reveal quite a bit of variation but no clear interpretation. The hazy atmosphere prevents the sudden shock of discovery that characterized the Voyager and Galileo flybys of the moons of Jupiter, revealing little more than
fuzzy Rorschach blobs. With less than 1% of the surface mapped, researchers suspect that Titan has a
young surface shaped by processes that have yet to be revealed.

Celestia is the most beautiful toy. It's a free (open source) simulator of the universe, including breathtaking models of known planets. Watch Jupiter rise over Io or follow the course of a solar eclipse. [more inside]

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.

Reflections on a Mote of Dust "We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam."
Carl Sagan "Pale Blue Dot"
