Venus is apparently so bright this month that it’s casting visible shadows. Now that’s cool! Unfortunately, while I can see Venus perfectly well, there’s way too much light around to see anything resembling a Venusian shadow. I don’t think I’ll have a chance to drive out into the desert by sunset in the next few days.

The Moon and Venus, sitting in a tree
This view of the Moon and Venus was taken from our apartment balcony earlier this evening.
I also took a picture yesterday, from the top of a parking structure near John Wayne Airport (we went to a show at UCI later that evening.) You can see the red trail an airplane left as it crossed the frame:
Having seen that pairing last night, I knew I had to be ready to catch it today! I figured the Moon would be a lot closer, but I hadn’t expected it to actually pass Venus tonight. It really gives you an idea of how far the Moon moves in 24 hours. (or, in this case, roughly 23 hours, since yesterday’s picture was taken at 6:00 and today’s was taken at 5:10).
To be honest, I wasn’t actually certain it was Venus. It was my first thought, because of the brightness and the color, but I kept thinking it was too far from the sun. I kept trying to convince myself it was Jupiter or maybe Saturn (it wasn’t red enough for Mars, and besides, I’d seen Mars on the other side of the sky the night before). When I looked it up and realized it was Venus, I started remembering my days in high school when I would walk to school for a 7:00am “zero period” class. In winter it would sometimes be just dark enough when I left to see the planets and the brightest stars. I would keep my eye on Venus as the sky brightened, trying to see how late I could still see it by knowing exactly where to look.
That Belt of Venus Thing
About a month ago I posted about noticing the Belt of Venus—the red band that circles the entire horizon just after sunset—and the Earth’s shadow on the sky. I snapped this picture on the drive home this evening. This is looking east, away from the setting sun.
If you look at the right edge of the picture, behind the silhouette of the tree, you can just see the red band fading into the dark gray of the Earth’s shadow.
(And to think, I almost brought the good camera with me this morning… Update: It turns out that I did bring it, and just didn’t realize it was there. Oh, well.)
Kilauea, Craters, and Hot, Hot Lava
Kilauea is often called the world’s most active volcano. It’s been erupting continuously since 1983 at vents several miles away from the caldera. The eruptions are still inside Hawai‘i Volcanoes National Park, but the lava hasn’t stuck to the boundaries as it flows to the sea.
So late on an April afternoon, we started driving down Chain of Craters Road toward the ocean, hoping to see (from a safe distance) lava pouring into the ocean. The road is named because it connects a series of craters left behind by old vents. At first we stopped at all of them. They ranged from large craters like Keanakako‘i to fifty-foot-deep holes filled with rubble a dozen feet from the road. Soon we realized that would take way too much time, and stuck with the ones that looked particularly interesting.
I don’t recall which crater this one was at (probably either Puhimau or Pauahi), but there was a trail up to a wooden viewing platform. I stopped at one point along the trail and took this picture of a small tree on the edge of the crater.
Look, up in the sky!
A few nights ago I was walking around sunset, and decided to look for something that had been mentioned last week on the Astronomy Picture of the Day: the Belt of Venus.
Somehow I’d never noticed that after sunset, the band of red encircles the entire sky at the horizon. Even more amazing, if you look away from the sun you can actually see the Earth’s shadow on the sky as a slightly darker blue below the pink. It reminded me of the view of Mauna Kea’s shadow on the cloud layer below. Oddly, though I didn’t pay any attention to it at the time, the Belt of Venus is clearly visible in that photo!
I guess at sunset I’m most likely to be looking at, well, the sunset. Or focusing on whatever it is I’m doing at the time.
This was Thursday night, so the moon was almost full. It rose just below the Belt of Venus, just inside the shadow. So close to the horizon, the moon illusion was in full effect, and it looked huge!
And me without my camera. *sigh*
