How Does Fire Burn in Microgravity?

Kirstin Fawcett

If you’ve ever watched a TV or movie in which a conflagration roars through microgravity, you've probably wondered: How do flames burn in space?

In the above video, DNews quenches your curiosity over why fire behaves differently in space than it does on Earth. Citing experiments conducted by NASA scientists since 2009, DNews demystifies how fire in space expands and spreads, ponders why combustion can occur without any visible flames, and explains why finding the answer to these questions might help us make technological advances. Oh, and as for cinematic scenes in movies like Gravity, in which fiery balls of flame float through the air? Turns out they're scientifically accurate.
