Don Pettit ISS startrails shot

While Chemical Engineer Dr Don Pettit was up on the ISS doing Chemical Engineering stuff, he also did some photography. And wow.

Those yellow streaks are city lights as the ISS speeds over the surface of the earth, and the blue/white flares are lightning. The white vertical stripes in the distance are star trails.

There’s a bit more to this image than simple long exposure, but fortunately, Doc Pettit has also done a video so that when you’re up in space, you’ll be able to recreate his work. In the meantime, go and have a look at the Flickr album with the rest of his amazing photos.
