text: As the stellar temperature increases, the UV flux increases and it ionizes the gas surrounding the central star, and can excite emission from molecules, heat the dust, and even begin to break apart the molecules and dust grains.
text: We now know that green color to be from very hot oxygen atoms in the gas surrounding the central star.
text: While WFPC2 is best used to study the hot, glowing gas, which is the bright, oval-shaped region surrounding the central star, NICMOS allows us to see deeper into the nebula and view material that cannot be seen at visible wavelengths.
text: The white is emission from the hot gas surrounding the central star; the red and pink represent emission from cool molecular hydrogen gas.
