Fire is the end result of the combustion process, which comes about from the combination of fuel, oxygen, heat and the chemical reaction which causes the fuel vapors to ignite...the two most obvious characteristics are heat and light, which vary according to the material being burned...wood gives off a yellowish light when burning and is relatively cool when compared to magnesium, which gives off a brilliant white light and is much hotter...
Fire also releases various gases from the substance or substances being burned, including oxygen, but most of these byproducts are toxic...

Hi. One other point is that fire requires gravity. The heated part such as a wick or a house needs to have the hot combustion gases removed and replaced by fresh air. In space (in a spacecraft) fire behaves much differently. The last Columbia mission had done many experiments on what happens to flame in micro gravity. : http://microgravity.grc.nasa.gov/combustion/
