NASA to Provide Live Coverage of Lunar Eclipse

On Saturday morning, April 4, 2015 not long before sunrise, the bright full moon over North America should turn a lovely shade of celestial red during a total lunar eclipse. Beginning at 6 a.m. EDT through the end of the eclipse, NASA Marshall will offer live Ustream video and NASA astronomer Mitzi Adams will take Twitter questions via @NASA_Marshall. Use the hashtag #eclipse2015 to send your questions.

A live Ustream view of the lunar eclipse will be available here on April 4 starting at 6:00 a.m. EDT:

The lunar eclipse will be visible from all parts of the United States.  Eastern North America and western South America can see beginning stages of the partial umbral eclipse low in the west before sunrise April 4, whereas middle Asia (India, western China, mid-Asian Russia) can view the ending stages of the partial umbral eclipse low in the east after sunset April 4. Greenland, Iceland, Europe, Africa and the Middle East won’t see this eclipse at all. A world map of eclipse visibility is available here. The total eclipse will last only five minutes.

This eclipse marks the third in a series of four lunar eclipses in a row, known as a “tetrad.”  The first in the series occurred on April 15, 2014, with the second in the tetrad of eclipses in September of 2014, and the final will be September 28, 2015.

For a total lunar eclipse to happen, the Moon must be full, which means it is directly opposite the Sun, with Earth in between.  The eclipse happens when the Moon moves into the shadow cast by the Sun shining on Earth.  We don’t have an eclipse every   month because sometimes the Moon is above the shadow, sometimes below.

During the eclipse, the Moon often looks reddish because sunlight has passed through Earth’s atmosphere, which filters out most of its blue light.  This eerie, harmless effect has earned the tongue-in-cheek nickname “blood moon.”

A telescope is not needed to view a lunar eclipse– just find the Moon in the sky and enjoy.
