When the lunar eclipse begins, the bright moon dims as it enters the outer part of Earth's shadow, called the penumbra. The deep tint of a full lunar eclipse is visible once the moon enters the deepest part of Earth's shadow, or umbra. The bright-red color appears once the moon is fully engulfed in the shadows, and it's the reason "blood" moon is a popular moniker for lunar eclipses.
To a certain extent, lunar eclipses reveal something about Earth, too. "Lunar eclipses ... reflect our world," astronomer and podcaster Pamela Gay told Space.com in an email. "A blood colored moon is created [by] ash from fires and volcanoes, ... dust storms and pollution all filtering sunlight as it scatters around our world. A grey eclipse is clear skies.
"Our world can change the appearance of another world, and during an eclipse, the universe lets us see this color play," she said.
The Jan. 20-21, 2019 total lunar eclipse will last 1 hour and 2 minutes, according to NASA's Goddard Space Flight Center lunar eclipse projections.
The full experience, from the start of the partial eclipse to the end, will last 3 hours and 17 minutes.
