A Lovely Thing In The Sunset Sky Tonight

It was stunning – the pictures might have been a touch better if I had been able to grab a tripod, but given the last few days of panicking and packing, I’m not sure I could put my hands on a tripod in less than about an hour (or six) if my life depended on it. So holding my breath, being really still, bracing on the neighbor’s mailbox, and shooting a lot of pictures and hoping for one or two that didn’t suck will have to do for tonight.

The two-day old moon is on the left (370,557 km away), Venus on the right (225,892,785 km away).

The 6% crescent of the moon is illuminated by direct sunlight – the rest of the moon is illuminated enough by reflected Earthlight so you can see the dark mare areas.

With a better setup and a bit more magnification, you would see that both the moon and Venus are showing the same crescent shape and (to an excellent first approximation) the same percentage of illumination.

Angles! Geometry! Science! Math!

It’s also just very pretty, dangling up there in the twilight.
