Male Speaker: An eclipse occurs when a celestial body moved in front of another cutting off the view from an observer. A solar eclipse seen here in this animation happens when the moon passes between the sun and earth. As the moon moves in front of the sun, it will cast a shadow that will travel across the planet. The shadow will have a dark part called umbra where the sun's light is blocked and the day turns dark for about 7.5 minutes. To the observer standing in the umbra, the sun is obscured by the moon and in total eclipse causing it to be dark enough for brighter stars of the night sky to make a brief appearance. At another place on the earth in the later part of the shadow called penumbra. The sun light is only blocked and at this point an observer will see a partial eclipse.
