This is what fire looks in space! Fire is a very different and mysterious creature when it burns in a microgravity environment. Usually, flames in the presence of gravity (i.e. on Earth) form under complex chemical reactions. But gravity ensures that the flame on a candle, say, forms a ‘droplet’ shape — hot air rises, pulling in cool air behind it, shaping the flame. But in the absence a strong gravitational field — like the microgravity environment in the ISS — fire transforms into a very alien configuration. Rather than hungrily expanding to pull in oxygen like its terrestrial counterpart, the microgravity flame stays put, burning as oxygen flows towards it. Learn more >> bit.ly/11LF3GA
