Candle Flames in Microgravity
NASA pages discussing the USML Experiment.
The burning of a candle relies on thermal convection to carry away waste gas and draw in fresh oxygen. Convection is possible due to the differing densities of gases at different temperatures in a gravitational field. Hence, the study of candle flams in microgravity (near-zero gravity) is an area of rich and unusual phenomena.

Select a temperature between 3000 and 10,000 degrees, and see the Planck spectrum for that temperature plotted. Stars have a radiation pattern which is governed largely by this formula. The user can perform photometry on that curve by selecting either a blue, green, or red filter.
