Gear up for the March, 2014 campaign!
Citizen scientists from around the world have contributed 4906
data points so far this year - thank you! Read more about the first campaign in our inaugural Globe at Night Newlstter.
Can you find Orion?
Orion looks very much like a person. First, you should spot Orion’s Belt, which is made of three bright stars in a straight line. One of Orion’s legs is represented by the bright star Rigel, one of the brightest stars in the night sky. His two shoulders are made of the stars Bellatrix and Betelgeuse. You can see Betelgeuse’s reddish color without a telescope.
Practice finding all the Globe at Night Constellations or review the Magnitude Charts.
The current campaign is using the Constellation Orion. Check out the dates and constellations
for our other campaigns during all 12 months of 2014.
