ECLIPSE - the Moments of Wonder


Computer Graphics

Explain the principles of solar and lunar eclipses using computer graphics. Sometimes, it is expressed more realistically by synthesizing actual images.

 

This is a computer graphic video that explains why the moon in the shadow of the Earth looks red during a total lunar eclipse. Here, the moon used footage from an actual total lunar eclipse.

 

Seen from space, this simulation shows how the Moon casts a dark, narrow shadow onto the Earth. Around it is a larger but lighter shadow. In this area people see just a partial solar eclipse.
To see a total eclipse, you must be within the central shadow. It traces a path that can cross half the globe, but might be only 200 kilometers wide.
The shadow travels up to 3,000 kilometers per hour. So from any one place, the Moon’s shadow will create a total eclipse lasting mere minutes.

 

While a total solar eclipse occurs almost every year, it can be seen only from along a narrow, and often remote, path. If you remain in one place and wait for a total eclipse to come to you, you will wait an average of 400 years between eclipses!
