Through next week, the <A href="http://www.globe.gov/GaN/" linkindex="5">GLOBE at Night</A> project invites <A href="http://antwrp.gsfc.nasa.gov/apod/ap080722.html" linkindex="6">people from all over the world</A> to go outside at night, look up, and see! Specifically, people are invited to go out an hour after sunset and look for the <A href="http://en.wikipedia.org/wiki/Orion_(constellation)" linkindex="7">constellation Orion</A> toward the west. Rather than count <A href="http://antwrp.gsfc.nasa.gov/apod/ap090210.html" linkindex="8">Orion's stars</A> directly, however, the <A href="http://www.globe.gov/GaN/student.html" linkindex="9">GLOBE at Night</A> website has made things easier by providing several <A href="http://www.globe.gov/GaN/observe_magnitude.html" linkindex="10">star charts</A> to which you can compare your <A href="http://www.globe.gov/GaN/observe_finder.html" linkindex="11">view of Orion</A>. Possible matches extend from a <A href="http://www.globe.gov/GaN/images/40N_m3_b.jpg" linkindex="12">bright sky</A> where only a few Orion stars are visible, to a very <A href="http://www.globe.gov/GaN/images/40N_m7_b.jpg" linkindex="13">dark sky</A> where over 100 Orion stars are visible. <A href="http://www.globe.gov/GaN/analyze.html" linkindex="14">Pictured above</A> are results from <A href="http://www.noao.edu/outreach/press/pr08/pr0805.html" linkindex="15">last year's sky observation campaign</A>. Since 2009 is the <A href="http://www.astronomy2009.org/" linkindex="16">International Year of Astronomy</A>, it is hoped that an even better map can be created this year. By <A href="http://antwrp.gsfc.nasa.gov/apod/ap040808.html" linkindex="17">participating</A> in this easy and fun activity, you are helping <A href="http://antwrp.gsfc.nasa.gov/apod/ap081005.html" linkindex="18">humanity</A> to better <A href="http://www.darksky.org/ " linkindex="19">understand</A> how <A href="http://antwrp.gsfc.nasa.gov/apod/ap010827.html" linkindex="20">light</A> <A href="http://www.youtube.com/watch?v=s9rhdq1DRMM" linkindex="21">pollution</A> is changing across the Earth. </P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;"> </td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/BA0663A0-5C23-43F6-842E-8DDE6034C462/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
