The last total lunar eclipse until 2010 will be visible tonight starting at about 8:45 p.m.

A total lunar eclipse occurs when the full moon passes into Earth’s shadow and causes it to be blocked from the sun’s rays. During an eclipse, the sun, Earth and moon line up, leaving a darkened copper-looking moon.

Saturn and a bright star named Regulus will be visible as well during the eclipse. They will be located on either side of the moon, according to NASA’s Web site.

Unlike solar eclipses, a lunar eclipse does not require protective eyewear.

The event will end at approximately 12:09 a.m. tomorrow.
