When the moon passes through the Earth's shadow, it causes the moon to look very unusual for a short period of time. This event is called a lunar eclipse, and it occurs roughly twice a year. There's one viewable to folks outside of North America on June 15, so sit back and learn more about how lunar eclipses work in this video!

This video is also available in stereoscopic 3D, viewable by many kinds of 3D devices, including common red/blue paper glasses that you might have lying around! To view this video in 3D, click here: http://youtu.be/F5JRVOw6mes

  • I've seen the red moon lunar eclipse.

  • All day your own footage !!!

  • the earth's limb acts like a rim of a convex lens. It refracts sunlight called lensing effect. (refer- eclipse.gsfc.nasa.gov/LEcat5/a­ppearance.html)

    the refracted red-orange light passes through the umbra and eclipsed moon appears like red hot iron.

    Because of maximum absorption (or scattering) of colors like green, blue etc through atmosphere, their presence is negligible within umbra.

    Corrections- dont diverge blue color, show only red & orange colors

    I m a physics simulation teacher

  • Definitely stunning film , Thank you
