Amelia Posted May 30, 2007 Share Posted May 30, 2007 I agree bevin. Many times while visitng relatives in eastern Oregon we would sit out in the yard and stargaze. It's so dark out in the middle of no where that you can see a very defined swath of the milky way. Totally awesome!

Amelia Posted June 3, 2007 Share Posted June 3, 2007 Jupiter, Vesta, and the Milky Way Credit & Copyright: Jimmy Westlake (Colorado Mountain College) Explanation: In this gorgeous skyscape, gas giant Jupiter along with the stars and cosmic dust clouds of the Milky Way hang over the southern horizon in the early morning hours as seen from Stagecoach, Colorado, USA. Recorded on Thursday, Jupiter is the brightest object near picture center. Along with the stunning Milky Way, Jupiter is hard to miss, but a careful inspection of the view also reveals main belt asteroid Vesta. Of all the asteroids Vesta is the brightest and is now just bright enough to be visible to the naked eye from locations with very dark, clear skies. Vesta (as well as Jupiter) appears relatively bright now because it is near opposition, literally opposite the Sun in planet Earth's sky and closest to Earth in its orbit. For Vesta, this opposition offers the best viewing in many years. The year 2007 also coincides with the 200th anniversary of the asteroid's discovery. Starting late next month, NASA plans to launch the Dawn mission intended to explore Vesta (and Ceres) and the main asteroid belt.

Amelia Posted August 16, 2007 Share Posted August 16, 2007 A Star with a Comet's Tail 08.15.2007 Science@NASA August 15, 2007: Astronomers using a NASA space telescope, the Galaxy Evolution Explorer, have spotted an amazingly long comet-like tail behind a star streaking through space. The star, named Mira after the Latin word for "wonderful," has been a favorite of astronomers for about 400 years, yet this is the first time the tail has been seen. http://science.nasa.gov/headlines/y2007/15aug_mira.htm?list213022 Quote <p><span style="color:#0000FF;"><span style="font-weight:bold;"><span style="font-style:italic;">"Do not use harmful words, but only helpful words, the kind that build up and provide what is needed, so that what you say will do good to those who hear you."</span></span> Eph 4:29</span><br><br><img src="http://banners.wunderground.com/weathersticker/gizmotimetemp_both/US/OR/Fairview.gif" alt="Fairview.gif"> Fairview Or</p> Link to comment Share on other sites More sharing options...
D. Allan Posted August 25, 2007 Share Posted August 25, 2007 How big is our universe? Harvard University has a nifty web site to give you a tour at http://www.cfa.harvard.edu/seuforum/howfar/ "This website shows how generations of explorers have taken us, step by step, ever further into the vast expanse of the universe. It is a journey of discovery that has only just begun." Quote dAb O frabjous day! Callooh! Callay! Link to comment Share on other sites More sharing options...
