ABSTRACT

On its voyage through the solar system, the Galileo satellite passed planet Earth and recorded three unique features-an atm osphere rich in highly flammable oxygen, a stream of radio emissions in the MHz frequency, and a red light-absorbing pigm ent over m uch of the surface, land and sea. The red-absorbing pigm ent was due to chlorophyll, the oxygen from past pho­ tosynthesis. The radio emissions indicated the possible presence of an in ­ telligent life form!
