Cassini flies within 25 kilometers of Enceladus tomorrow
Hot on the heels of MESSENGER's flyby of Mercury comes another big event, the closest-ever flyby of Enceladus by Cassini. This one is at an altitude of only 25 kilometers, or 16 miles. That's a low flyby! It's half the altitude of any previous... More»

The full story of Earth-impacting asteroid 2008 TC3
Over the last 24 hours it has been tiring but really fun to watch the drama of asteroid 2008 TC3. It has happened so quickly that it's necessary to convert all times to UTC in order to see how events have unfolded across the globe. Fortunately for... More»

First images from MESSENGER's second flyby of Mercury
Without question, this is the money shot from MESSENGER's second flyby. I think this image provides an answer to all of those people who suggested that seeing Mercury again -- even if it was from a new perspective -- might be dull because it would... More»

No pics of the 2008 TC3 fireball have shown up on the Web yet...
Well, I have to shut down the computer for the night; I haven't seen any fireballs show up on any of the places I usually watch for space news. Hopefully there will have been somebody, somewhere, who saw it, and managed to capture it in some... More»

Movie, made with real photos, of asteroid 2008 TC3 on approach to Earth
Coolness: here's an animation of several images of 2008 TC3, captured by G. Sostero, E. Guido, V. Gonano, and P. Camilleri at the Remanzacco Observatory just a few hours before it was to hit. Sostero was one of the winners of one of the Society's... More»

Simulation of the final moments of 2008 TC3
Here's a neat animation of the view from boulder-sized asteroid 2008 TC3 as it makes its final approach to Earth tonight. A point I didn't appreciate when I wrote my first post on this is that the asteroid actually enters Earth's shadow at 01:50... More»

A three-meter-diameter piece of the sky is falling
Many, many congratulations are due to Richard Kowalski and the rest of the team at Mt. Lemmon Observatory in Arizona, who, last night, made the first discovery of an object that proved to be on a collision course with Earth. The fact that I'm... More»
