Lunar "Wolf Moon" Eclipse (2019)
The 2018 Blood Moon Lunar Eclipse, will last 1 hour and 43 minutes, during which Earth's natural satellite will turn a spectacular red or ruddy-brown color. From start to finish, the entire celestial event will last nearly 4 hours, the longest in a century.
Traditional names for January Moons are: Buck Moon, Thunder Moon, Wort Moon, and Hay Moon.
Lunar eclipses occur when the Moon passes through the shadow of the Earth. They only occur during a full moon when the Earth is between the moon and the sun. There can be total, partial, and penumbral lunar eclipses.
Similarly, solar eclipses occur when the Earth passes through the Moon's shadow.
This umbra illusion tartan created by designer Carol A.L. Martin, uses amongst other shades of black, white, and grey, a particular shade called "eclipse."
In August 2008, the Full Moon slid across the northern edge of the umbra. Entertaining moon watchers throughout Earth's eastern hemisphere, the lunar passage created a deep but partial lunar eclipse. This composite image above uses successive pictures recorded during the eclipse from Athens, Greece to trace out a large part of the umbra's curved edge. The result nicely illustrates the relative size of the umbra's cross section at the distance of the Moon, as well as the Moon's path through the Earth's shadow.
