In 2018, the world will experience three partial solar eclipses and two total lunar eclipses — but whether you can see them depends on where you live. The first event is a total lunar eclipse that happens on the morning of Jan. 31. This eclipse will be special! The moon will be both "super" and "blue," and if skies are clear, skywatchers in North America will be able to see all or part of the eclipse.
In this edition of Mobile Astronomy, we'll highlight the rare "Blue Blood Supermoon" total lunar eclipse and tell you how to use your favorite astronomy app to preview it. We'll also help you use your app to explore how lunar eclipses work.
A Blue Blood Supermoon eclipse
On Jan. 31, 2018, skywatchers across much of the world will receive a postholiday gift: the total lunar eclipse of a full supermoon that is also a Blue Moon! Unlike last summer's Great American Total Solar Eclipse, lunar eclipses are completely safe to look at because the sun is below the horizon. Any sunlight that reaches the eclipsed moon has to pass over the Earth's horizon, painting the moon with reddish light — hence the nickname "blood moon" for eclipsed moons.
