mars and stars

Standard

There’s something wonderfully strange about a machine sitting on Mars and, in the middle of the night, shining a UV light on rocks and taking pictures. The Curiosity rover has been doing just that. Here’s a 30-second exposure taken under the glow of ultraviolet LEDs. It’s looking for fluorescent minerals. I’m looking for fossils. I don’t see any.

Here’s a lovely photo that at first glance might appear to be stars, but each speck of light is actually a billion stars, or thereabouts.
