Southern Moonscape
The Moon’s south pole is near the top of this detailed telescopic view. Looking across the rugged southern lunar highlands it was captured from southern California, planet Earth. At the Moon’s third quarter phase the lunar terminator, the sunset shadow...
Lunar Eclipse Perspectives
Do we all see the same Moon? Yes, but we all see it differently. One difference is the apparent location of the Moon against background stars — an effect known as parallax. We humans use the parallax between our eyes...
