The mission of the International Dark-Sky Association (IDA) is to preserve and protect the nighttime environment from any adverse effect of artificial light. See IDAs Best Choice Lighting page for resources. Check out Sky and Telescope's Saving Dark Skies for links to helpful, interesting and pertinent articles. IDA is encouraging everyone to support Earth Hour, which is a global initiative to "turn off the lights" in cities around the world for one hour, starting at 8:30pm local time on Saturday, March 26, 2011. It is intended to bring together a diverse group of community, municipal, corporate and non-governmental organizations, to heighten awareness of the impacts of climate change on the world, and to inspire individuals and businesses to take practical action to reduce their own carbon footprint. Learn more at EarthHour.org. The value of the night is explored in Ecology Of The Night. National Park scientists on the Night Sky Team work to preserve the Natural Lightscapes, dark night skies above our national parks. Take action for a dark sky!

For
the legend of the Easter Bunny
Find Three Rabbits in the Heavens! Moon Rabbit as shown above is always seen in the Full Moon. Lepus The Hare ~ the Cosmic Bunny is located below Orion's feet. He's easier to see in a dark country sky. Use this fun star map for orientation, then compare to this Easter 8:30pm Sky Chart. This cosmic bunny might just have an Easter Egg for you! Bunny's Footprints belong to a magical bunny and you can track these footprints in Scorpius throughout the year.

The Myth ~ Scorpius the Rival of Orion Scorpius is the legendary killer of Orion. Orion was a great hunter who bragged about his skills until the gods grew tired of his boasting. The scorpion was sent to punish Orion, who never thought of such a small creature as a threat. Once he was stung, it was too late. Both were placed in the sky although Orion's last wish was that he never be in the sky as the same time as the scorpion. Thus, Scorpius rules the northern hemisphere's summer while Orion rules the winter skies. StarrySkies.com Orion
and His Rival

During Aries as Orion sets in the west and Scorpius rises in the east around midnight, Leo the Lion, as if chasing winter Orion out of the sky, lies overhead as the master of spring. This cosmic Lion rules spring. Regulus and Leo the Lion Spring Up!
May Spring's Emerging Opportunities Bless you!

March 20 - April 20, 2011 Jupiter quickly sinks out of sight, below the western horizon, during the first week of Aries. The planet is in exact conjunction with our Sun 4/6. Jupiter reappears in the morning sky, very low in the east, 30 minutes before sunrise at the end of April. 4/30 Dawn Map Mercury, reaching its greatest distance from the setting Sun 3/22, gives its best 2011 evening performance. 3/22 7:30pm Map Mercury fades and disappears into the Sun's glowing light during the last week of March. The planet is in exact conjunction with our Sun 4/9. At the end of April use binoculars to spot Mercury in the early morning sky, between Venus and Jupiter. 4/30 Dawn Map ~ Historic First: A Spacecraft Orbits Mercury Saturn reaches opposition 4/3 and is at its best during Aries, at its closest (800 million miles), biggest and brightest, and out all night long. The Lord of the Rings rises at sunset, lies overhead at midnight and sets at sunrise. The planet's yellowish glow is eye-catching above (west of) bluish Spica. The planet at magnitude 0.4 shines a little brighter than this star. Early April 10pm Map ~ 4/4-7 Star Gazer 5min-Video Use the Big Dipper to locate Saturn (see Arcturus below for details). Saturn's rings are opening, revealing more and more of their northern face. The planet's ring tilt is 9º in April. Saturn brightens and grows bigger as it approaches Earth and its rings open to reflect more light. Generate images of Saturn's ring tilt as seen from Earth with the Solar System Simulator. Venus at magnitude -3.9 is breathtaking in the morning sky around 6:00am, however it is sinking toward the Sun and is only seen shortly before sunrise. 3/29 - 4/1 the Crescent Moon is elegant near Venus 3/29-3/31 Map ~ 3/31 6am Map ~ 4/1 Map/Text At the end of April several planets line-up with Venus and the Crescent Moon. 4/30 Dawn Map/Text Mars is too close to our central luminary to be seen. Morning Mars won't be easily seen until mid-May, 30 minutes before sunrise.
The Pleiades star cluster can be seen sinking in the west in the early evening. Look for the line-up, west to southwest, of the sparkling blue-white Pleiades, red Aldebaran and brighter red Betelgeuse. Winter Stars The Pleiades set about 12:15am in the beginning of Aries and by its end at 10:45pm. Springtime Pleiades Orion The Hunter is found with the winter stars sinking in the southwest at sunset. The stellar giant fully sets in the beginning of Aries by 1:15am and by its end at midnight. Use Orion's stars to navigate this area of the sky. Winter Stars Orion helps one find the Winter Triangle, the Great Winter Hexagon and the Valentine's Star! Sirius the brightest star in the heavens can be seen high in the south as the sky darkens. Sirius sets in the beginning of Aries around 1:00am and by its end at 11:30pm. Regulus and Leo the Lion spring up in the east at sunset. Arcturus, a bright golden star, can be seen low on the eastern horizon at 9:00pm. Use the handle of the Big Dipper to arc down to golden Arcturus, then spike down to blue-white Spica in the south! Helpful Image In 2011 yellowish Saturn, technically at its best 4/3, lies above (west of) bluish Spica. A large triangle is formed by these 3 colorful celestial bodies. Early April 10pm Map Binoculars make vivid their colors. Big Dipper Navigation
