Answer
The Earth and Sun have different emission spectra because of nuclear fission, which causes the Sun to emit all forms of electromagnetic radiation. This radiation travels through space and hits Earth. Earth's atmosphere absorbs all forms of visible radiation, which causes the planet to warm and subsequently radiate Infrared radiation back into space.
