Today's solstice marks the astronomical beginning of the northern hemisphere's summer.
Astronomer Anthony Ayiomamitis recorded this image of the solstice Full Moon rising above Cape Sounion, Greece. The twenty-four hundred year old Temple of Poseidon lies in the foreground. In this single exposure, a telescopic lens makes the Moon loom large, but even without optical aid casual skygazers often find the Full Moon looking astonishingly large when seen near the horizon; often referred to as a moon illusion.
