I'm an avid scuba diver. Ever the domain of the wealthy, scuba diving required both access to the ocean and a shite ton of money for travel & equipment. Not really having any of it, this awesome hobby just kinda passed me by.
This photo was taken aboard the International Space Station (ISS) during a nighttime pass. You can also see a Soyuz spacecraft (left) and Progress spacecraft (right) docked with the Station in the foreground.
