East of Antares
23.06.2006
East of Antares, dark markings seem to sprawl through the crowded star fields toward the center of our Milky Way Galaxy. Cataloged in the early 20th century by astronomer E. E.

Sunrise Solstice at Stonehenge
21.06.2006
Today the Sun reaches its northernmost point in the planet Earth's sky.

19.06.2006

Crescent Neptune and Triton
18.06.2006
