Way-cool Martian flyovers by Doug Ellison
Doug Ellison has been playing with Martian digital terrain models recently, to great effect.
New maps of Pluto show pretty amazing amounts of surface change
I just posted my writeup of today's press briefing on a new map of Pluto produced from Hubble images. The main conclusion was that Pluto has shown an astonishing amount of changes across its surface between 1994 and 2002 -- more, in fact, than any other solid surface in the solar system.
Spectacular Hubble view of the aftermath of an asteroid collision
Hubble has caught an astonishing view of something that's never before been observed, the aftermath of a collision between two asteroids in the main belt.
Mars Express animation of Phobos' shadow transiting Mars
For the first time ever, Mars Express' Visual Monitoring Camera has imaged the shadow of Mars' moon Phobos crossing the surface of Mars.
A pretty picture of Concepcion crater
It looks like the rover team thinks Concepcion is pretty enough (in both aesthetic and a scientific senses) to be worthy of the full-color Pancam panorama treatment; color frames started arriving on Earth over the weekend.
Cassini Aegaeon and Prometheus awesomeness
There were many, many treats waiting on the Cassini raw images website this morning. Yesterday, Cassini traversed the G ring, taking photos all the way.

Asteroid 2867 Steins
This description of asteroid 2867 Steins is based upon an article published in the January 8, 2010 issue of Science by H. Uwe Keller and numerous coauthors and on a related press release.
Spirit's still "extricating"
It's been two months, now, that extrication efforts have been going on. It's discouraging that the Mars Exploration Rover Spirit isn't out of the trap.
400 Years of the Galilean Satellites
It was 400 years ago today that Galileo discovered smaller planets attending the planet Jupiter.

New Mercury Atlas
The United States Geological Survey has just released a new atlas of Mercury, the first to be based upon the three flybys worth of image data gathered by the MESSENGER mission.
Evaporating exoplanet
CoRoT-7b was the first unambiguously rocky planet to be discovered and was quite small, at under five Earth masses. But a press release issued today suggests that its history probably has little to do with Earth's.
Kepler discovers its first five exoplanets
Congratulations to NASA's Kepler mission team on their announcement of the discovery of its first five exoplanets (planets around other stars).
