This weekend, many parts of the world, including North America,

will be treated to a total lunar eclipse.

So here with your viewing guide, how it happens, what to expect,

and when to head outside is Michelle Nichols,

director of public observing at the Adler Planetarium in Chicago.

There is a total eclipse of the moon on Sunday evening, January 20th, 2019.

A total lunar eclipse occurs when the moon passes through the shadow cast by the Earth into space.

When this happens, sunlight shines onto the Earth and passes through the atmosphere that is all the way around the edge of the earth.

The blue light from the sun is scattered away by our air, leaving the red colors of light.

So many times, a lunar eclipse turns the moon a dark, dusky red, as we are seeing the collective light from sunrises and sunsets around the entire

edge of the earth at once. The moon can appear coppery orange, red, gray, or it may seem to

almost disappear completely during a lunar eclipse. This eclipse will be visible from all of

North and South America, and Hawaii will see it in progress when the moon rises. The main part of the eclipse starts

at 1033 p.m. Eastern, 7.33 p.m. Pacific on Sunday evening, January 20th, when the moon starts to pass

into the darker part of the Earth's shadow. This is the partial phase of the eclipse. Go outside

and face east or southeast and look for the moon in the sky.
