Eclipses are one of the most beautiful celestial events to watch, both with unaided eyes or with optical instruments. There are eclipses of the Sun and Eclipses of the Moon. While one needs to be very careful while watching a Solar Eclipse, Lunar Eclipses are absolutely safe to watch. Go through this article to find out the best circumstances to view this Lunar Eclipse.
What is a Lunar Eclipse?

A Lunar Eclipse is caused by the alignment of Sun, Earth and the Moon in the given order. The alignment has to be precise and even if its off by fraction of a degree, a Total Lunar Eclipse could become a partial one (no blood moon basically). The white light of the Sun passes through the atmosphere of the Earth and gets scattered and absorbed. Only red light (and spectrum close to it) gets through, giving the Moon its characteristic red colour during an eclipse.
What is so special about this eclipse?
A Lunar Eclipse can happen only on a full moon day and the eclipse on 31st January 2018 is also on a date when the moon is closer to the Earth than usual during a full phase a.k.a Super Moon. Another speciality of the this full moon is that it is the second full Moon of the month a.k.a Blue Moon.

You don’t wanna miss it for anything. Get those telescopes and binoculars out.
