The Longest Lunar Eclipse of the Century is Approaching Next week's lunar eclipse will last almost <br />two hours, which will be the <br />longest lasting lunar eclipse in 100 years. It will occur late on July 27 <br />into the twilight hours of July 28. Unfortunately, North America <br />is the only continent <br />where it won't be visible. Europe, South America and <br />Australia will get partial views. Africa and Asia will <br />have the best views. The eclipse will appear red, which is known as a "blood moon." Bruce McClure, via EarthSky Astronomy enthusiasts will be getting a twofer <br />that day. Mars will also reach its opposition, <br />greatly illuminating in the night sky. The next lunar eclipse available to North Americans will be Jan. 21, 2019.
