Galaxy and a Twist

• Awesome, indeed! RT @BadAstronomer: 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

This 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

• Via @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. #

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! RT @BadAstronomer 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. #

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!

Leo, Saturn… and Comet Lulin?

Leo, Saturn… and Comet Lulin?, originally uploaded by Kelson.

I figured I’d try spotting Comet Lulin from my back yard. I found Leo and Saturn easily enough, but just couldn’t see anything that looked like a comet. It should be a little to the right of Saturn, going by Sky & Telescope’s chart.

Too much light pollution, I guess. And unlike the bad astronomer, I didn’t have any binoculars to try a closer look.

On the plus side, I did spot a meteor out of the corner of my eye, off to the left of this field.

Figuring the camera might pick up something I missed, I took a few long exposure shots, running 15 seconds with the equivalent of ISO 1600. There’s a dot next to Saturn, but I’m not sure if it’s the comet or a star.

I’ll have to try again in San Simeon. Light should be much less of a problem, though clouds might be an issue.

Waitaminute

Listening to “Into the West” (end credits song from Lord of the Rings: Return of the King). Lyric, “Across the sea a pale moon rises.”

It’s all about crossing the sea into the west to go to elf heaven. Presumably the speaker is standing at the Grey Havens, waiting for the ships to arrive and carry her off to the Undying Lands, looking across the sea…to the west.

So since when does the moon rise in the west?

Admittedly, it’s a fantasy setting, but Middle Earth is set up to be a mythical past for the real world, so I’m fairly certain the sun and moon still rise in the east…

Moon and Venus Above Palms

Stellar Triangle

I managed to get a few shots of the near-conjunction of the crescent moon, Jupiter and Venus tonight before they sank into the haze.

The first two shots were taken at twilight (well, dusk, really), around 5:05–5:10 PM PST, while the third was taken at 5:30, after night had fallen.

Jupiter and Venus

This is actually from a couple of nights ago, but the view as I left the office tonight was about the same (though the lights were just starting to turn on in this picture).

It’s really odd to walk out of the building into a lot that’s normally lighted (even when I head in to do emergency server maintenance at midnight) and see it completely dark.

Well, not completely dark. There was a little light leaking from windows behind me, and streetlights filtering through trees, and what I could see of the sign on the building across the street. Nothing compared to some of the camping trips I’ve been on, or the drive through Ka‘u at night. But for a suburban office building, it was a change.

Edit: Oops! For some reason I’ve been convinced that this was Saturn, but it’s actually Jupiter.

Exoplanets: Say Cheese!

I remember being bowled over when astronomers first detected planets around other stars. Nowthey’ve actually managed to get pictures!

Of course, they’re about as detailed as pictures of the stars at a science-fiction convention panel taken from the back of the room, or the band on stage from the upper-top-fifth-tier seating (see! that dot there is so-and-so!), but still…it’s a start.

There’s one photo from Hubble of the planetary debris disc around Fomalhaut, with a little dot that apparently has been tracked in other images, consistent with being in orbit around the star. It’s estimated at being about the size of Jupiter and about four times as far out from its star as Neptune is from the sun.

Meanwhile: consider that we can see something the size of Jupiter even though it’s 25 light years away!

Then there’s one from the Gemini North telescope that has actually caught two planets in orbit around a star called HR 8799 — a photo of a planetary system!

Update: Hubblesite has more on Fomalhaut including this image showing Fomalhaut B’s location in 2004 and 2006:

Mercury

I have never seen the planet Mercury outside of photos. #

Eclipse Ring

Eclipse Ring, originally uploaded by Kelson.

I found this while looking through a box of old photos, in an envelope marked Lunar Eclipse and developed in June 1994. Most likely the May 25, 1994 eclipse.

I’m not sure, but I think the bright splotch near the bottom is actually the moon, and the clear image of the moon up near the top is a reflection inside the camera. I have no idea whether the ring is an atmospheric phenomenon that got picked up on the film, or just lens flare.

Anyway, scanned because I thought it looked interesting.
