Very cool site! You can see real-time images of where it's night or daylight on Earth. Great for showing equinox and solstice concepts. Also nice for comparing Northern and Southern hemispheres.
Very accurate space science here. Also, the site points out many space science misconceptions. Excellent resource!
Ever have the urge to look at some 3-D images of space stuff? Throw on the blue/red glasses and enjoy!
