The sky’s sheer size and beauty takes our breath away, but what exactly makes the sky so blue? Due to a phenomenon coined Rayleigh Scattering, the spectrum of colors ranging from violet to red, either pass through or deflect off of the earth’s atmosphere, which is made up of mostly nitrogen and oxygen. Longer wavelengths of red, yellow and orange colors of the spectrum have little affect on these tiny particles that make up our atmosphere. However, shorter wavelengths of blue are deflected and are scattered all around us, causing the sky to appear blue no matter where we look.
Our Planet, Our Universe: Earth and Space, opening as a permanent exhibit on September 25, 2010, will provide guests the opportunity to discover and explore black holes, Martian terrain and of course, why our sky is blue. Allow us to beam you up to enjoy the vastness of the cosmos, as well as the complexity of our fascinating planet.
