Fire behaves very differently in microgravity — and this ISS experiment shows it beautifully. 🔵 With no “up” in 0g, hot gases don’t rise, so the flame becomes a perfect sphere. Combustion completes more cleanly, giving the flame its blue color. When you see sudden orange patches, that’s soot forming — a brief moment of incomplete burning, similar to flames on Earth. As the droplet burns, tiny asymmetries push it gently through the air until the fuel is gone and the flame silently disappears. |

In zero gravity, a candle flame behaves in a completely unexpected way. Instead of forming the familiar yellow, teardrop-shaped flame that rises upward on Earth, the flame becomes a small, blue, floating sphere. This happens because, without gravity, hot gases don’t rise and cold air doesn’t sink—eliminating the convection currents that shape flames on Earth. On our planet, gravity pulls cooler, oxygen-rich air downward while hot combustion gases rise, stretching the flame upward and giving it a

SpaceXer Tees on Instagram: "NASA’s FLEX Burns Fuel in Zero Gravity 🤯 Flame Floats as a Perfect Sphere Instead of Rising What does fire look like in space? 🤯 On Earth, flames rise because hot air goes up and cool air replaces it—but in zero gravity, there’s no “up” or “down.” So when NASA’s FLEX researchers ignited a tiny fuel droplet aboard the International Space Station (ISS)… something unbelievable happened. 🔥 The flame didn’t rise. 🔥 It didn’t flicker. 🔥 It formed a perfect floating sp

Physics Uncovered on Instagram: "Spherical flames in space occur because of microgravity, and they look very different from flames on Earth. On Earth, gravity causes hot gases to rise and cooler air to flow in from below. This buoyancy-driven convection stretches a flame upward into a teardrop shape. In space, however, gravity is essentially absent, so hot gases do not rise. Without convection, oxygen reaches the flame only by diffusion, evenly from all directions."

Made To Automate on Instagram: "A fascinating NASA experiment revealed a phenomenon where flames behave entirely differently without the pull of gravity. On Earth, convection creates the familiar teardrop shape, but in space, this process is absent. The result is a perfect, spherical flame a ball of fire that burns at a lower temperature and with surprising efficiency. This research provides crucial insights into combustion dynamics in microgravity, impacting future spacecraft fire safety design
