This illustration depicts a warm hued underwater landscape framed by a spherical cave opening. The microscopic building blocks of life - molecules, amino acids, proteins, bacteria, microorganisms, and extremophiles - appear to grow on surfaces and float throughout the composition. Ediacaran fossils are embedded in the surrounding rock. Hot smokers and stromatolites decorate the foreground and slime molds and lichens fill out the scene. A central hydrothermal vent emits glowing gold particles which coalesce into the shape of a human being. Molecular structures intersperse with these particles and drift upward toward the water’s blue-lit surface. The rippling reflection on surface resembles a distant spiral galaxy. From stars to life, we are the same.
