Orbital View: Evolving Earth

Adrienne just flagged a fascinating series of ten images from the Planetary Habitability Laboratory, and Emily whipped up five of them into this composite:

Visible Paleo-Earth Project, Planetary Habitability Laboratory @ UPR Arecibo

The images are pretty self-explanatory, but Abel Mendez has full details:

Here are simulated views of Earth, minus the clouds, from the position of five main geostationary weather satellites, each over a different longitude (145°E, 057°E, 000°E, 057°W, and 132°W). We used data from our Visible Paleo-Earth and SER to generate these views for ten periods encompassing the last 600 million years. During these periods our planet became more habitable for complex life. Look here for actual satellite images of Earth from these satellites.
