Impact Crater
In my posts about our field trip to Arizona, I showed my best pictures of meteor crater, but really none of them come close to expressing the feeling of standing on the brink of such a feature and trying to imagine an explosion big enough to carve it out. I just came across a photo by Stan Gaz that does a much better job than my snapshots (click to follow …
100th Carnival of Space!
Back in the early naive days of space carnivals, we looked to the future and were certain that the 100th carnival of space would actually be a carnival, and that it would actually be held in space. Sadly, protests from the carnival spin-and-barf ride-cleaner’s union quashed that dream before it could become a reality. Luckily, we found a new equally awesome place to have the 100th carnival: One Minute Astronomy! …

Discoveries in Planetary Science
The Division for Planetary Sciences of the American Astronomical Society just released several short sets of slides summarizing recent important discoveries in planetary science that aren’t yet in textbooks. They are very nice, easy to understand summaries so I encourage you to check them out. The topics so far are: Mars Methane, Extrasolar Planet Imaging, The Chaotic Early Solar System, Mars Sulfur Chemistry, and Mercury Volcanism. Follow those links to …

The Ares Launch Vehicles: How We're Going Back to the Moon
I just came across this excellent video describing the Ares rockets that will be replacing the shuttle and taking us back to the moon (and possibly to near-Earth asteroids and Mars). I can’t seem to get it to embed, but here’s the link, and a blurb: “Imagine a rocket the size of a small skyscraper. Now imagine shooting it into the air with so much force that it goes from …
The Pale Blue Dot
What better Earth day message is there than this? Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer …

Cassini Questions Answered
I got a bunch of questions about the BigPicture feature on the Cassini extended mission from an “enthusiastic” commenter, with whom I happen to be related (Hi mom!), and I thought I would dedicate a post to answering them. 1. How does a Jovian equinox work? Start by reviewing how one on earth works. Well, the pictures are of Saturn, not Jupiter, but that doesn’t really matter since equinoxes work …
Big Picture: Cassini's Extended Mission
The Big Picture, the Boston Globe’s photojournalism blog, does it again! This week they have a spectacular set of images of Saturn and its sattellites from the Cassini extended mission. Well worth a look. I especially liked the images showing Saturn’s upper atmosphere acting like a lens, causing the rings to apparently bend as they approach the planet. Did you know that the Earth’s atmosphere does the same thing? Sunrise …
