There’s a meme going around Twitter called #ZodiacFacts, mostly random astrological statements. I figured I’d post some actual, y’know, facts about the Zodiac.

  • The Zodiac is the set of constellations through which the sun, moon and planets appear to move when seen from Earth.
  • In a dark sky, away from light pollution, you can sometimes see Zodiacal light after the sun has set.
  • Due to cycles in Earth’s orbit, the present-day constellations of the zodiac no longer line up with those used by astrology.
  • In a REALLY dark sky, you can see the Gegenshein: sunlight reflecting off of interplanetary dust.

Venus and Mercury

At the age of 34, I’ve finally seen the planet Mercury.* It’s notoriously difficult to spot, but when I read that it was going to be very close to Venus for the next few days, I had to try.

As it turns out, I was able to see it from a local grocery store parking lot. I left the car just as Venus was becoming visible, concerned by the clouds starting to drift past, and left the store to a clear twilight sky and a “star” below and to the right of Venus…exactly where Mercury should be!

*Of course I’ve seen photos, but I’d never seen the planet directly with my own eyes — or if I have, I didn’t recognize it.

Do you believe there is other intelligent life in distant galaxies? If no, why not? If yes, do you believe this is something to be feared and avoided or actively sought out?

Could there be? Certainly. Have we seen any sign of it, or any reason to believe that it is there? Not yet.

I remember seeing a poster in one of my high school science classrooms that said something like, “Either we are alone in the universe, or we are not. Both possibilities are overwhelming.” A quick Google search determines that it’s a paraphrase of Arthur C. Clarke, though there seems to be some disagreement as to his original phrasing, and whether the two ideas were overwhelming, staggering, terrifying, etc. However it was phrased, I think it’s a fitting summary.

It was fast. Anticlimactic, really. It took a few reloads to get the Comic-Con International home page up, but once I could click on the reservation link, everything went smoothly. I was done by 9:05.

The reservation page was actually optimized!

  • Just one image: a banner across the top.
  • Everything was on one page, including the list of hotels, the personal info, and the hotel choices.
  • Hotel selection was done by client-side scripting, so there was no wait for processing between selections (and no risk of typos confusing their processing system later today).

This is a huge deal, especially compared to Travel Planners’ horribly overdesigned 2008 forms — yes, forms, plural — that kept bogging down. (I never even saw last year’s, though I tried for an hour and a half to get in.)

On the downside, that one page does load a half-dozen script files, but that doesn’t seem to have slowed it down much.

In case none of your 12 choices were available, they asked for a maximum price you’d be willing to pay for another hotel that’s not on your list. I vaguely recall this being a feature of the old fax forms, but I don’t remember being asked this on the phone last year.

I was surprised to find that they didn’t want credit card info immediately, but that’s good from a streamlining perspective as well. The hotel choices, room type, and contact info are critical in order to make the reservation in the first place. Payment can be done later, so in a rushed situation like this, it’s better to handle it later. Plus, not asking for credit card information means that they could run the site without encryption, speeding things up a bit more.

I would have liked to have gotten a confirmation number for the request, or an email, just so that I could be sure that I was in their queue. And to be sure that I entered the right email address. And the right start and end dates. And…well, you get the idea. I’m a little paranoid about the process at the moment.

Here’s hoping that the back end of the process, and sending out confirmations, goes as smoothly as the front end did.

Update: Short answer: it didn’t. Long answer: I’ve written up what went wrong, at least from the guests’ point of view.

One evening last week I looked to the west and saw a bright light above the horizon. I couldn’t tell whether it was moving or not, and wondered: was it an airplane, or Venus?

I couldn’t remember whether Venus was visible in the evening or morning (or at all) right now. It was roughly in the direction of an airport, so it could easily have been a helicopter or an airplane traveling at an angle roughly in line with my line of sight. By the time I got home, buildings and trees blocked the horizon, so I didn’t think much more of it.

I’m in California. Interestingly enough, thousands of miles away in Ohio, people have been seeing a bright light in the west every night for the past week and making UFO reports.

Last night I decided to see how early I could spot Venus, and caught it fairly high in the sky just after sunset. It was hard to see without really looking for it because the sky was still light, but it became a lot easier as the sky darkened. Not surprisingly, as it set and brightened in the dimming sky, it passed through roughly the area I remembered seeing the unidentified light last week. Mystery solved.

I don’t understand why, in a world full of airplanes, helicopters and the occasional blimp — not to mention a world where we see stars and planets every night (barring clouds and light pollution) — people jump past these mundane explanations when they see a light in the night sky and decide it must be an alien spacecraft.
