Fire in Space
In the microgravity of the International Space Station, fire behaves differently than on Earth. Without gravity, heated air does not rise, so flames form perfect spheres as oxygen molecules randomly drift into them. This image, taken in the Combustion Integration Rack, shows a spherical flame enveloping fuel clusters.
