It was January of 2004 when the elegant curve of the Vichada first caught the attention of geologist Max Rocca of Buenos Aires. Could the course of the river have been shaped by the circular outlines of an impact crater? Rocca decided to find out.

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.

In less than 24 hours, a newly discovered asteroid known as 2010 AL30 will be zipping past Earth at an altitude of approximately a third the Earth-Moon distance. There's no chance it'll hit us, but it's generating a lot of excitement in the community of amateur and professional near-Earth asteroid observers.

Last week in Science magazine appeared the first peer-reviewed article on the results of Rosetta's September 2008 encounter with the smallish main-belt asteroid Steins. This morning I got a chance to sit down and read the article, and I wrote up a summary.

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.

Not quite ten years ago, the Near Earth Rendezvous (NEAR) spacecraft arrived at the near-Earth asteroid Eros. NEAR accomplished many firsts.
