397E-438-Bright Darkness

Most of the humans on planet Earth have never witnessed that the natural night sky is not dark; but rather it is alive with it's own lights. To see for yourself, pick a dark sky place near you like the Cosmic Campground International Dark Sky Sanctuary from the International Dark Sky Association's website, darksky.org, and recruit a friend. Do a bit of research on how to achieve and sustain your night vision. Bring a red filtered flashlight, reclining lawn chair, star maps, binoculars, warm clothes, a telescope if you have one, and snacks. Keep on the look out for special events. The American Meteor Society's website will let you know when to expect meteor showers. Most humans have never seen the glowing light pyramid called the Zodiacal light which is produced by ice particles and dust in the solar system. In the northern hemisphere it is prominent in the evening sky in February, March and April. During the same months it lights up the predawn sky in the southern hemisphere. Star clusters scattered around the sky can be enjoyed with binoculars or a small telescope. New Moon's from May through October will provide you opportunities to explore the Milky Way with your naked eye or pair of binoculars. This adventure will fill you with wonder at what might be out there. Last but not least Mars will dominate the night sky during much of 2018 as it and the Earth come near to each other. For a time in late July of 2018 Mars will even outshine the giant planet Jupiter in the night sky.
