While the resemblance to Earth’s oceanic relief is limited, we aimed to create a credible planetary representation.

Although these fluctuations are extremely subtle, the most prominent differences occur on a physical scale of about one degree—roughly 1/180th of the sphere’s diameter—appearing as small dots across the full circle.

For reference, the Milky Way’s plane runs along the equator, with the center positioned at the heart of the image. The blue and brown colors indicate temperature fluctuations of up to 300 µK around a 2.725 K average.

8. The Anthropocene & Present
The spiral culminates with Homo sapiens. Our species' impact causes biodiversity loss & rapid, human-accelerated climate change.

7. The Cambrian Explosion
The Cambrian Explosion sparks a burst of complex multicellular life in the oceans. Life later moves to land. A meteor causes dinosaur extinction.

6. The Oxygen Revolution
Cyanobacteria cause the Oxygen Revolution ~2.4B years ago. Endosymbiosis leads to complex cells with organelles like chloroplasts.

5. Origin of Life & Early Earth
Life begins with LUCA & DNA. Early photosynthesis evolves as global oceans and tectonic plates shape the young Earth.
