Space Candle

Original - In a microgravity environment, convection does not carry the hot combustion products away from the fuel source, resulting in a spherical flame front, such as in the candle seen here. This is a rare example of a diffusion flame which does not produce much soot and does not therefore have a typical yellow flame.

Reason

I found this image very interesting and highly informative.

• Weak Support Quality is not great, but it's rare and has significant EV. ~ ωαdεstεr16_«talk^stalk» 17:29, 18 February 2009 (UTC)

• Weak Oppose I'm concerned about the quality. Feel free to sway me. ~ ωαdεstεr16_«talk^stalk» 04:40, 17 February 2009 (UTC)

• • My guess is that it is noisy since the flame wouldn't be very bright at all. Noodle snacks (talk) 09:19, 17 February 2009 (UTC)

    • I understand how difficult it would have been to take this photo, but I mean it looks like a cell phone took it. Am I missing something? ~ ωαdεstεr16_«talk^stalk» 00:53, 18 February 2009 (UTC)
      • Well if its not very bright, then either high ISO film or high ISO digital would be required to capture it reasonably quickly, hence the noise. I don't know what the technical details actually are, but imo it will suffice unless a wikipedian flies into space and take a better image. Noodle snacks (talk) 02:51, 18 February 2009 (UTC)

• Support. I thought I'd seen this at better quality before, but it may have been a small printed grayscale version thereby hiding many of the flaws. So I'll give it the benefit of the doubt - definite EV. --jjron (talk) 15:10, 27 February 2009 (UTC)
