Today is the first total lunar eclipse of 2014 and millions of people are watching the Blood Moon as it is happening.
Here is the live stream:
Basically Earth blocks the sun and our only natural satellite turns red. So how does it look from the moon and how come it is red?
“The Mars Underground” has put together two beautiful videos and a short description:
With the lunar horizon in the foreground, the Earth passes in front of the Sun, revealing the red ring of sunrises and sunsets along the limb of the Earth. The “No Stars” frames omit the starry background and include an alpha channel. In the early morning hours of April 15, 2014, the Moon enters the Earth’s shadow, creating a total lunar eclipse. When viewed from the Moon, as in this animation, the Earth hides the Sun. A red ring, the sum of all Earth’s sunrises and sunsets, lines the Earth’s limb and casts a ruddy light on the lunar landscape. With the darkness of the eclipse, the stars come out.
The city lights of North and South America are visible on the night side of the Earth. The part of the Earth visible in this animation is the part where the lunar eclipse can be seen.
