By contrast, earthshine blurs the complex details of the entire sunlit side of our planet into a single, globally averaged measurement that can be made from robotic observatories on the ground. For more than a decade now, Philip Goode at Big Bear Solar Observatory in California has led Project Earthshine to do just this. The project now includes a second robotic observatory in the Canary Islands, and Goode eventually hopes to grow it into a worldwide network. What they’ve found so far is that Calendar Moon 25 Earth’s reflectance, also called its albedo, is much more complex and variable light than traditionally thought.
So it’s fitting that this space-age stepping stone begin everyone’s personal exploration of the solar system.

These markings bear a resemblance to lunar tallies that have been documented among various indigenous peoples, including Native Americans.
