Last year, on August 21, 2017, the entire United States could witness the first coast-coast solar eclipse in the last 100 years (99 years to be exact). That was a beautiful thing to see and it reminded us of how wonderful could space actually be.
This year is not going to be an exception, at least not for entire North America. Canadians and Americans are going to witness the first Super Blue Blood Moon Eclipse in 150 years. This is going to happen on January 31, 2018.
And what is that? Well, that is a rare cosmic event where 3 lunar events occur at the same time.
– The Supermoon;
– The Blue Moon;
– Lunar Eclipse.
This January 31st moon will be a supermoon. This means that it will be really big and that happens when the moon is closest to the Earth during its elliptical orbit. It will appear to be up to 14% larger and over 30% brighter than the regular moon.
This doesn’t mean that the moon will be blue! This is an expression scientist use for a rare phenomenon where we have two full moons in one calendar month. So don’t expect the moon to be really colored in blue.
This happens when Earth finds itself between the Moon and the Sun. This shadow will give the Moon some kind of a reddish glow. Scientists refer to this as the Blood Moon
And naturally, when we combine all those 3 events, we get the Super Blue Blood Moon Eclipse.
You would think that The Earth would just conceal the moon with its shadow. But it is not that simple.
Earth has an atmosphere. It is not just a rock. So sun rays have to go through that atmosphere too! And if we know that sunlight is not yellow but white, and we see it as yellow because of the Earth’s atmosphere. So we can conclude that our atmosphere changes the light of the Sun. So as the sun rays travel through our atmosphere in short waves, it turns to red as it leaves it. That lights, in the end, hit the surface of Moon. This is one way to put it. An oversimplified way.
Some cultures believed that Blood Moon is a bad omen. An omen of the apocalypse! However, this event is a common thing. Don’t worry.
And you should not be scared of looking at this event. You will not need any sunglasses as you did need them back in August of 2017.
