The midnight glow over Limfjord. This is how dark the sky is during the summertime.
Milky Way will be again available to photograph first in the beginning of August,
What's causing the unusual ray of white light extending upward from the central horizon? Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System rises prominently before sunrise and is called zodiacal light. The dust originates mostly from faint Jupiter-family comets and slowly spirals into the Sun. Pictured, in front of the zodiacal light, is a spectacular view of Horseshoe Bend of the Colorado River. Emitted from well behind the zodiacal light is a spectacular sky that includes many bright stars including Sirius, several blue star clusters including the Pleiades, and an assortment of red nebula including Barnard's Loop in Orion. The 30-image composite was taken earlier this month in nearly complete darkness only six inches from the edge of a dangerous cliff.
