The Value of Space Exploration, via Phil Plait’s response.

Neil Gaiman on The Fairy Feller’s Master Stroke, a painting by a madman that’s inspired its share of stories.

And from Comics Worth Reading, our WTF entry for the day: Paradise by the GoPhone Light. It’s a commercial done in the style of a music video, featuring Meat Loaf and Tiffany as the parents of a kid who wants a GoPhone. Completely surreal, especially once the random explosions start.

It’s just occurred to me that, aside from it being some sort of cell phone, I have no idea what a GoPhone is. [/me types "gophone" into Google] Ah, OK. Pre-paid cellphone. Meh. (And now I’m imagining how much spam is going to get posted to this thread. *sigh* )

Cities at Night, seen from Space

This is cool: a fascinating tour of the world’s cities as seen in visible light from the International Space Station.

Cities at Night, an Orbital Tour Around the World

It’s interesting to see how just lighting illustrates different patterns in city development. European cities have this star topology, US cities tend to stick to the north/south grid. Different countries tend to use different colors of lighting, with the western cities more yellowish and cities in the middle east and Asia more greenish. There’s a view along the Nile, where the river runs through the middle of a channel of lights, beyond which everything is empty.

There’s also a mosaic of the Los Angeles/Orange County/San Diego area, which really points out that there’s quite a bit of emptiness still in the OC area: The Santa Ana Mountains to the northeast, and the San Joaquin Hills to the sourthwest, make large dark areas. The northwest plain melds seamlessly into the Los Angeles area, while a narrow (but very bright) channel winds its way through the middle before opening up into south county.

The downside, as pointed out in the comments, is that this is all wasted energy. With lamps that direct all of their light downward instead of out into space, we could light our cities with less energy and keep the skies dark for stargazing.

Mauna Kea Sky Shadow

Today’s Astronomy Picture of the Day features a view of Mauna Kea’s shadow on the sky, just at the tail end of last week’s lunar eclipse:

I couldn’t help but be reminded of our visit to the summit in April 2005, just at sunset, when I took this similar (but decidedly less cool) photo:

Atmospheric Optics explains why most mountains’ shadows look triangular when viewed from their summits.

Strange Visitors

There’s been a surprising number of visitors today to my post about getting up at 2:30 A.M. for last August’s lunar eclipse. Strangely enough, they’re not only looking for the same phrase, “lunar eclipse pictures,” but they have the exact same referrer, down to options and encoding. The fp-today parameter leads me to suspect that some module on Yahoo’s homepage (not one I can see, though) included a link to this set of search results. Though I suppose it could have been a newsletter or a blog with more regular readers than mine.

Another surprise: visits from commentary on last night’s Clinton/Obama debate. The comment thread includes a link to my post on JMS’s Londo/G’Kar campaign signs. Found while skimming the comments for links: T-shirts for the Capricorn ticket, Roslin/Airlock.

And then there’s the surge in searches for the Black Flash, no doubt inspired by people reading today’s Something Positive strip. In addition to landing directly on the profile, people are coming in from the Wikipedia article, and finding Flash Foreshadowing via an image search.

Fire by Night

With the winds dying down, the smoke from the Santiago Fire clung loosely to the mountains most of the day. Unfortunately, smoke from the new fires down on Camp Pendleton drifted up the coast to take its place, bringing back the yellowish sunlight. Also, without the wind to clear them away, ashes left a thorough coating on anything outside. Work was somewhat calmer, with everyone (and their houses) finally accounted for. Power kept flickering throughout the afternoon, though. Between 4:30 and 5:00, something massive flared up, sending a new plume of smoke into the sky.

I ended up leaving the office after dark, giving me a chance to take some pictures of the orange moon (it was actually a bit past first quarter on Sunday, and it’s not quite full today*).

I also went looking for spots to take pictures of the red glow coming from the mountains. There’s a bridge near the office where I frequently take pictures of the hills, and I managed to find a spot where I could set up my mini-tripod and still have a view of the glow. There was one brighter patch which seemed to be changing shape, which I figured might actually be flames.

Afterward, I drove up to a cul-de-sac on Quail Hill which I’d discovered at lunch. I just parked my car at the end of the road, put the camera on top of it, and started trying shutter speeds.

The vantage point gave me a better sense of geography. The Irvine Spectrum area lies in the foreground, with the 4 tall office buildings (the two in the middle are under construction) and the bright neon proclaiming the movie theater. The shopping center stretches off to the right. The empty area behind them consists of undeveloped land from the former El Toro Marine Base and the hills that burned earlier this week. The clusters of lights about 1/3 of the way up are, I think, Foothill Ranch. That places the glowing area in Santiago Canyon.

Even though some of the houses up on Quail Hill seemed to still be under construction, they had an efficient neighborhood watch going. I must have been there only 3 minutes before a van pulled up into a nearby space. A guy stepped out. No labels, no uniform. I said something along the lines of, “Hello, I’m taking pictures of the glow from Saddleback.” He said, “It’s still going, huh?” “Yeah.” I muttered something about exposure times, and he got back into his van and drove off.

*Strangely, I just discovered that my Nightmare Before Christmas calendar has the phases of the moon shifted… well, out of phase. It lists a new moon for Friday instead of a full moon. Everything else is consistent with this placement. Except reality.

Look! Up in the Sky!

The event runs from October 1–15, so there’s only 4 nights left! Get out there, and take a look at the stars!

Lunar Eclipse pics

I decided to go for it, and set my alarm for 2:30 AM (ick) to see the eclipse. The moon was nearing totality at that point, with a too-shallow crescent near the bottom and the rest in slightly reddish shadow. My original plan was to lie down on the balcony and watch, but it turned out there was a tree in the way, but if I went over to the other end, by the patio table, I was able to see it.

I watched as the crescent shrank to a sliver, and finally the moon was shaded dark red to dull red to light red to a much dimmer white than usual. The deeper reds slowly spread across its face, edging out the brighter colors near the edge of the Earth’s shadow.

I brought my cheesy little digital camera, and took some photos. It promptly started warning me the battery was low, and I had to dig around in the dark to find the spare. I think this is the best of the pictures, as far as showing the eclipsed moon itself goes:

Eclipsed Moon, 3:13 AM

Earlier in the evening I was testing different shutter settings. I thought this photo from the floor of the balcony turned out interesting:

Yes, that’s lit by moonlight (in a long exposure).

OK, I’m going out to take one last look at the moon (I think I heard the downstairs neighbors’ door open a few minutes ago, so at least I’m not the only one up for this) and then go back to bed. I’ll look through my photos again tomorrow and post anything else that looks good.

Update: Here’s a shot from deeper in totality, just after the mid-point of the eclipse:

Eclipsed Moon, 3:40 AM

And here’s the Pleiades, which I spotted when I turned around and looked up. A far cry from this, but hey, I figured I was doing pretty well to be getting photos of stars with this type of camera in the first place.

I think the last time I saw the Pleiades, Hyades, Taurus and Orion in August, I was something like 14 and on a trip with my scout troop to do whitewater rafting. We slept out under the stars and I just happened to wake up at 3 in the morning.

OK, sleep is calling to me. Signing off…

Update 2: After I went to bed, I realized that I shouldn’t have dismissed my idea of scrounging up some film and pulling my manual SLR camera out of the closet. Between the better optics, more shutter control, and an actual telephoto lens, I probably would have gotten considerably better pictures. I just don’t think we have any rolls of film lying around that haven’t expired, and I didn’t want to run out at 11:00 to get some. Ah, well. Something to think about for next time.

Also, I realized that these blurry pictures look kind of like a Moon-sized version of Mars. Hmm, that might confuse some people.

Update 3: You have to check out Thursday’s APOD: an incredible telescopic image of the moon taken during totality.

Lunar Indecision

I’m still trying to decide whether I should set an alarm to wake myself up at ski-o’clock in the morning to see tonight’s/tomorrow’s lunar eclipse. I mean, I skipped the Perseid meteor shower a few weeks ago, but that would have required not only getting up in the wee hours of the night, but driving somewhere with less light pollution.

I mean, I should be able to walk outside and look out at a blood-red moon… at 3:00 in the morning.

*grrr*

Update: Ah, the wonders of text search and delayed indexing. It seems that lots of people are searching for the phrase, “eclipse tomorrow,” leading to a spike in hits to this entry from last March… even though today’s post would be a more appropriate destination.

Update 2: I went for it. Here’s my write-up.

Pumpkin Moon

We were driving home from visiting relatives this evening, and noticed a dull orange ellipse on the horizon, appearing and disappearing between trees. It didn’t take long to realize it was the moon, just beginning to rise.

As the freeway twisted and turned, and we went through areas full of houses, retail centers, and trees, we lost and regained sight of it. The moon illusion was in full effect, making it look huge, plus the bottom edge was flattened, just like the sun at sunset—only you can look at the moon much longer. (Well, except when you’re driving.)

It rose through a bank of clouds or haze, climbing through dark bands, and slowly turned from orange to yellow, then turned paler. By the time we got home at 10:00, it had assumed its normal circular shape (with a tiny bit shaved from the upper right, since it was a day past full), and didn’t look particularly bigger than usual.

We don’t get to see the moon so close to the horizon very often. For one thing there are mountains to the east, but more importantly there are buildings all around. As we saw with the drive home, it doesn’t take much height to block the horizon from view. By the time we got home, roughly an hour past moonrise, it was just visible over the tops of the nearby buildings from our balcony.

Deja View

Follow-ups to two past blog entries.

First, remember on our most recent trip to Las Vegas (last March) we repeatedly encountered a slow-moving, hand-painted truck labeled “Henry’s Moving” on the drive out. Well, after a trip to Fry’s this past Sunday, we spotted it again.

Second, for the first time in 1½ years, I managed to spot Venus in broad daylight again. I went downstairs to grab a snack about 3:20 this afternoon, and noticed the first-quarter moon in the East. Remembering how I located Venus the first time, and already in the shadow of the building, I traced a line from the moon toward the sun, and found it, a tiny white point in the light blue sky. It was almost directly overhead, and just outside the area around the sun where the sky turns increasingly white. I lost sight of it, but managed to locate it again before I went into the cafe, and once more when I walked out.

I probably looked silly, staring straight up at the sky. But hey, how often do you see another planet during the day?

Edit: I went back down a few minutes later and took a photo. It actually showed up, which seriously surprised me.

Wow

If you haven’t already, go over and look at today’s Astronomy Picture of the Day. It’s an incredible shot of the Moon and Venus during last weekend’s conjunction.

Lunar Eclipse Tomorrow

There’s a lunar eclipse tomorrow. It looks like we’ll only get to see the tail end of it here in California, right at moonrise. Europe and Africa get to see the whole thing.

Interestingly, the map of where the eclipse will be visible manages to cover the major land masses almost exactly. The only region that won’t see it at all is the Pacific Ocean.

Crescent moon and Venus

I walked out the front door last night around 5:50 to pick up the mail, and immediately walked back in to get the camera, because this is what I saw:

My parents gave me a flexible mini-tripod for Christmas, and it proved very helpful here, as there was nowhere flat where I could set the camera and still get a good view. I ended up coiling it around a stair railing, which held the camera in place long enough to get a decent exposure.

I seriously thought about pulling my SLR camera out of the closet and seeing whether I had any film for it, but ultimately decided against it.

Daytime… Comet?

Well, I tried again at lunch to see if I could spot Comet McNaughton during the day, just in case it was still bright enough. No luck, but I set my camera on max zoom and took a set of pictures in roughly the right area, just to see if I could spot something.

And, well, I did. I’m just not sure what. This was 1:28 pm (33.66 N, 117.75 W), looking roughly southwest, with the sun placed behind a wall to the right. The sun is to the right and above the frame. I don’t have a good sense of distance in the sky, but this is in the right direction to be either Venus or the comet.

Or it could be a passing high-altitude airplane that I didn’t notice.

If it is the comet, the tail is completely invisible, as it should be stretching down to the lower left (away from the sun) and I can’t make anything like that appear with any of the image enhancement tools I’ve tried.

This is unprocessed. All I did was load it from the camera and crop it. And here’s a copy of the whole photo (this was at full ~3x zoom on a Canon PowerShot SD600) with the position of the object and the rough position of the sun pointed out.
