Document Summary

Hydrogen with other gas and clouds at the top. Low temperature emit infrared light we cannot see. Get brighter as it heats up ( changes from red to white ) The temperature of the objects effect its spectrum. Hot things are brighter ( per area ) The spectrum of hot things peak at a shorter wavelength. Uranus is cold so it emits infrared light (light that we cannot see) Light of all colours come from the sun. Methane gas absorbs red light and transmits. Methane cloud re ects the blue light back into space. Different molecules form cloud at different temperature. Red bands are lower-altitude clouds ( warmer and therefore brighter in infrared photo ) ( ammonium hydrosul de ) White bands are higher-altitude clouds ( cooler and therefore emit less infrared light ) ( rising air form ammonia clouds at high altitude ) The galilean moons (( lo, europa, ganymede, callisto ))
