Dude! This awesome image looks like a psychedelic 1970’s flashback. But is is actually a droplet of fuel burning in space, on board the International Space Station. NASA explains that because of the absence of gravity, fuels burning in space behave very differently than they do on Earth. The Flame Extinguishing Experiment on board the ISS is examining the combustion of such liquid fuel droplets, and in this image, a 3-millimeter diameter droplet of heptane fuel burns in microgravity, producing soot. When a bright, uniform backlight is placed behind the droplet and flame and recorded by a video camera, the soot appears as a dark cloud. Image processing techniques can then quantify the soot concentration at each point in the image.

This colorized gray-scale image is a composite of the individual video frames of the backlit fuel droplet. The bright yellow structure in the middle is the path of the droplet, which becomes smaller as it burns. Initial soot structures (in green) tend to form near the liquid fuel. These come together into larger and larger particles which ultimately spiral out of the flame zone in long, twisting streamers.

This image looks mirrored over the middle vertical. Any idea why ?
It’s totally awesome image and on my disk anyway 🙂
look closer, there are differences in the fringing (to be expected due to fluid/quantum effects, but net effect takes hold in large scale). its just like galaxies, how could galaxies be so symmetric, yet have diameters of thousands of light years across?
beauty of physics at work.
Because it looks better?
Possibly, but it’s confusing. We’re missing out on what’s happening on the other side of the droplet… or is that a solid surface?
Yes, I agree… I’d rather see the ‘actual’ representation of the phenomenon initially, to appreciate the science and THEN, if I choose, to see a stylized version for the ‘o-o-o’ effect.
Looks like an Acid Mothers Temple album cover…
Show me the video! 🙂
Now THAT would make a great ‘Burning Man’ at the Psychic deli….
