In the next few nights, comet Lulin can be seen in the eastern sky with the naked eye or better with binoculars. This is the comet's first visible pass near Earth. It's tail streaks normally away from the Sun and it's cloud(the size of Jupiter) glows green because it burns off cyanogen gas, diatomic carbon, and 800 gallons of water a second. Go out tonight and check it out with your kids. Here's an easy to figure out chart of when and where to look. Good luck!
