As part of a big, ongoing project to make a comparison chart of the dimensions and physical properties of solar system objects I've spent the morning tackling the difficult problem of summarizing the physical characteristics of the biggest things that are out there beyond Neptune.

Welcome 2011! I can't wait for what this year has in store. The prize for all of you who have enjoyed opening each door in the Planetary Society's 2010 advent calendar is one of the best views we can get of one of the biggest objects in the asteroid belt, Vesta.

Today the 365 Days of Astronomy podcast aired my contribution, What's in a Science Meeting?, about what scientists do at big meetings like the Division of Planetary Sciences.

An awful lot of the talks in the Pluto session on Tuesday morning, October 5, at the Division of Planetary Sciences meeting spent more time focusing on how bad weather conditions were during the astronomers' attempts to view Pluto as it occulted background stars than they did on any measurements or science that came out from the data.

I am just drowning in data right now, and I couldn't be happier.

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.

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.

A set of Mars image data taken by the Hubble Space Telescope a year ago was just released to Hubble's data archive. It was captured by Hubble's Wide Field and Planetary Camera 2 on January 30, 2008 when Mars was about 115 million kilometers from Earth.

Before I get to my notes from OPAG I want to minimally acknowledge today's news, which I'll have to get to in more detail later.
