The Lighthouse

The Lighthouse

"What is the meaning of life? That was all—a simple question; one that tended to close in on one with years, the great revelation had never come. The great revelation perhaps never did come. Instead, there were little daily miracles, illuminations, matches struck unexpectedly in the dark; here was one."

—Virginia Woolf


The Fading Milky Way

Light pollution is a growing environmental problem that threatens to erase the night sky before its time. A recent study revealed that perhaps two-thirds of the world's population can no longer look upwards at night and see the Milky Way—a hazy swath of stars that on warm summer nights spans the sky from horizon to horizon.

The Milky Way is dimming, not because the end of the Universe is near, but rather as a result of light pollution: the inadvertent illumination of the atmosphere from street lights, outdoor advertising, homes, schools, airports and other sources. Every night billions of bulbs send their energy skyward where microscopic bits of matter—air molecules, airborne dust, and water vapor droplets—reflect much of the wasted light back to Earth.
