The skies were surprisingly clear today. Four of us at work walked outside after sunset to a bridge near the office, and saw Comet McNaught. It was visible from ~5:10/5:15 to 5:28, at which point it slipped below the line of hills to the west.

We saw it against the red sky, slowly dropping through the (fortunately sparse) clouds. It was easily visible to the naked eye as a fuzzy white spot, with a hint of a tail pointing straight up that was a lot clearer in binoculars. The tail looked like a U or a V, fanning out at what looked like (but probably wasn’t) a 45° angle.

Well, my fingers are finally warming up. (I made the mistake of not grabbing my jacket, and went out just in my sweater.) Time to wrap stuff up.

Update January 13: I managed to catch another glimpse of it tonight. Unfortunately I was just arriving at the shop to pick up my car, and it was just closing, so I didn’t have a chance to watch it set (or see much more than a fuzzy white dot.) My watch said 5:02. By the time I got out, it had set beneath the building across the street, and there just wasn’t anywhere nearby enough with a clearer view of the western horizon.

On the plus side, I did manage to spot Venus while the sky was still light, and get a picture. It’s not quite as exciting as spotting it at one in the afternoon, but by adding more blue, you get an idea of what that looked like:

Update January 14:

I was looking over the photos I took last night (Saturday) and discovered I could actually find it by messing around with levels. On the left is the original photo, with a little bit of color correction to match what the sky looked like. The background’s still too bright to see the comet, though it was visible to the eye. On the right, I’ve adjusted the heck out of the image, and there’s a very slight bright spot right where it should be (I framed the shot so that the comet would be near the light pole, making it easier to find). Actually, now that I look at it again, it’s just barely visible in the less-processed photo on the left.

Also, this is cool: the comet has gotten bright enough to be spotted in daylight. (via Slashdot) I didn’t have any luck looking for it this afternoon, but I chalk that up to lower altitude and city haze.

Update January 15: I spotted something today, but I’m not sure what…

Space Shuttle Atlantis has landed safely. *whew!* I’m getting more nervous about shuttle missions lately. In part, it’s the greater focus on all the things that could go wrong. In part, it’s the realization that you know, the shuttle fleet really is aging.

But mostly, I think it’s the fear that, given reactions to the Columbia disaster, our nation may be only one disaster away from writing off space—or at least humans in space—entirely.

Speaking of Atlantis, the Bad Astronomy posted a fantastic photo by Thierry Legault of the shuttle and the International Space Station passing in front of the sun!

Some interesting comments by Warren Ellis in today’s Bad Signal on film budgets, and Superman Returns in particular.

$250 million puts you in spacelaunch-budget territory. For $250 million WB could’ve given Bryan Singer his own communications satellite and spent the change on a George Clooney movie.

This is the absurdity of modern Hollywood; that taking more than the GNP of Luxembourg in a single weekend is not actually enough to put a movie in the black.

It’s the “spacelaunch” comment that I find most interesting, as I made the same comparison a few years ago, from the other side of the fence: Assuming that the Spirit and Opportunity missions to Mars are typical, price-wise, it doesn’t make sense to complain that we’re “wasting” money on space exploration when a mission costs as much as two summer blockbusters. Manned missions are, of course, more expensive, but robotic missions? If we, as a society, toss away $250 million several times a year on mindless action flicks, what’s so terrible about spending a similar amount to learn something about our universe?

Yes, I know the difference is public vs. private funding. Movies are financed by studios and private investors, and space exploration is usually financed by governments, and therefore by taxes. But comparing the dollar amounts puts things in a different perspective—whether you’re astonished by the literally astronomical movie budgets, or realizing that exploring outer space is more down to Earth than it seems at first glance.
