This set illustrates a possible backstory for the matter that makes up life on Earth. The first piece depicts stellar nucleosynthesis, including the triple-alpha process to make carbon. The subsequent series depicts a supernova explosion, a nebula, and a protoplanetary disk. The third piece is an undersea hydrothermal vent at the end of the Hadean Eon (~3.8 billion years ago), a possible setting for the origin of life. The fourth piece depicts the chemistry of hydrothermal vent exhalations. The final series depicts key concepts in the ion-sulfur world theory for the origin of life.
