Look to the Western Sky after Sunset

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.

Galaxy and a Twist

  • Awesome, indeed! @BadAstronomer says:

    Awesome awesome AWESOME pic of the Milky Way’s heart, by 3 magnificent observatories. #

  • In a brilliant move, I have just twisted my shoulder funny 5 minutes before driving home. At least it’s the left shoulder. Still: Ow! #

Outer Planets: Viewing Neptune

NeptuneThis morning I saw some wavy clouds that reminded me of the patterns you see in pictures of Jupiter. I started thinking about gas giant planets, and had an odd moment of realization: when I was a kid, astronomy books didn’t have actual photos of Uranus or Neptune. They couldn’t have — there weren’t any! There were nice photos of Jupiter and Saturn from the Voyager missions, but Voyager 2 didn’t reach Uranus until 1986, or Neptune until 1989.

The really weird thing, though: modern astronomy books do have photos of Neptune — but the ones for general audiences probably all use the same picture I got as a framed poster when I was in high school. We haven’t been back in 20 years. Jupiter and Saturn have gotten a lot of attention, partly because they’re a lot closer and partly because their ring and moon systems are so fascinating. So we have a more continuous view of those planets and how they change over time.

Neptune? One snapshot (metaphorically speaking) of the planet from 20 years ago. Everything before and everything since then has been done with telescopes. Even the Hubble barely has the resolution to tell that the Great Dark Spot broke up sometime between 1989 and 1994. That’s something that maybe shouldn’t have surprised anyone, given how quickly storms form and dissipate on Earth, but back in 1989 it seemed so much like Jupiter’s Great Red Spot (going on 400 years or longer) that it was easy to think it too would be persistent.

It’s a good reminder that the universe beyond Earth does change with the passage of time…even on a human scale.

Fragile, Mondays, Eyes & Saturn

Butterfly Boucher: Scary Fragile

  • Great indie rock: Butterfly Boucher’s Scary Fragile for #MusicMonday #
  • Speaking of Butterfly Boucher, here’s our writeup of the concert we went to back in June. #
  • From @lol_spam:

    “TPA Report.” It should be a TPS Report, but the keys are, like, right next to each other. I guess even spammers can get a case of the Mondays. #

  • Yes! Realized eyestrain was a problem & finally got PC set up on my original monitor. Bigger is nice, but more importantly, it’s NOT BLURRY! #
  • Still not sure how I went 1.5 months w/o fixing the refresh rate on the temporary monitor. Usually the flicker drives me *consciously* crazy. #
  • Incredible new high-res image of Saturn! (via @ThisIsTrue) #

Touring the Mt. Wilson Observatory (17 Years Ago)

The Station Fire burning through the Angeles National Forest north of Los Angeles is expected to reach the summit of Mt. Wilson sometime tonight. In all likelihood it will damage or destroy the communications towers and the observatory complex. The Mount Wilson Observatory is an active observatory, and is also of historical importance because of discoveries made there over its 105-year history. In particular: Edwin Hubble’s* observations with the 100-inch Hooker telescope (shown at right) indicated that universe is much larger than was previously thought, and that it was expanding — observations that revolutionized astronomy and led to the current Big Bang theory.

I’ve been to the observatory once, on a tour my family took on August 8, 1992. We’d just come back from a trip to Florida where we visited Disney World and Cape Canaveral during the summer I was 16. I really wish I could remember more about the trip…but I took pictures and labeled them (though not in much detail). With the observatory threatened, I thought I’d dig them out and scan them**. You can see all eight on my Mt. Wilson Observatory Tour 1992 photoset on Flickr.

The Observatory’s website is apparently hosted on the grounds, so the fact that its fire status page is still responding indicates it’s still there and has power. The latest update says that they’re setting up a backup info page at http://joy.chara.gsu.edu/CHARA/fire.php, but that’s showing a 404 error right now.

*As in the Hubble Space Telescope.

**Scanning them was not a problem. Digging them out? That was a problem. I knew exactly which photo album they were in, and thought I knew where the album was. As it turned out, it wasn’t there. It was in an unopened box shoved at the very back of the long,narrow hall closet, such that I had to move 3 other boxes, several bags, and an unused CD rack just to see that it was labeled “photo albums” on top. Edit: And, oh yeah, the trail of ants along the wall, going after the long-forgotten bag of Halloween candy. The wall I kept brushing up against. How did I forget that part?

That’s the missing piece that makes the classic phrase more than a simple tautology. It’s not just that it’s in the last place you look. It’s that it’s in the last place you want to look.

Apollo+40, Comp Bits

  • Cool! @BadAstronomer asks:

    Are you following @ApolloPlus40? It’s tweeting the Apollo 11 mission “live” as it happened 40 years ago. #

  • Huh. I don’t think I’ve ever encountered a power-only USB cable before. Would be nice if it was LABELED as such. #
  • Ugh. “Refurb Madness.” Bad pun. Stay in the corner. #

Aliens and Social Bots

  • If NASA really knew about aliens, wouldn’t publicizing it be the best way to solve their chronic budget problems? #
  • Amazing how many “people” are sending Facebook messages to the postmaster account, offering helpful links to resources for improving uptime. #
  • Google’s Social Graph thinks I own Cute Overload. It seems to treat all LiveJournal syndication feeds as one profile, & I linked to K2R’s LJ feed with XFN. #

Night Sky

There’s something to be said for a night sky with so many stars that Sirius doesn’t stand out quite so much. #

No Comet For You!

Orion, Sirius, and Airplane, originally uploaded by Kelson.

I had hoped that the darker skies near San Simeon on the central California coast would have made it easier to spot Comet Lulin, but no such luck. First the clouds rolled in around sunset. I checked around 9:45 and they’d cleared enough to see very clearly out toward the ocean, but the lights of town were directly below Leo, so I drove down the highway a few miles to a scenic viewpoint with a wide parking area, stopped the car, and tried not to let passing traffic ruin my dark adaptation.

Once again, no luck spotting the comet (though I’ve at least determined that the bright spot next to Saturn was just a star), but an excellent view of the stars. And I spotted 4 or 5 meteors during the ~30 minutes I was out there, all in the direction of Orion and Canis Major. (One of them, maddeningly, flashed by just moments before one of my photos started.)

I did manage to catch an airplane as it transited in front of Canis Major and Orion, shown in this photo. (I should have called it a UFO.) And the view was far better than any night sky in suburbia, so the side trip was absolutely worth it!
