Most comets become active only when near the sun. This one is active, but distant, between the orbits of Saturn and Uranus, where sunlight is 1/225th as bright as seen from Earth.
Marc Toso tried 3 times to capture a photo of an ancient and remote petroglyph known as a waterglyph, on the Utah-Arizona border. The 3rd time was the charm.
This petroglyph is estimated to be between 2,000 and 1,000 years old. It might have been used as a navigation map to help locate water. Photo by Marc Toso of the website AncientSkys.com.
