Look to the sky! On the night of January 30 to 31, we will live on Earth a unique event: triple astronomical coincidence. We give you all the keys.
What Will Happen in Heaven?
In the early morning of January 30 to 31, 2018, the Earth will live a unique event. There will be three astronomical coincidences that were not repeated since 1866:
⭐ Blue Moon: this is the name given to the second full moon within the same month of the calendar. An event that happens approximately every three years.
⭐ Supermoon: this situation occurs when the Moon is at the closest point in its orbit around the Earth -perigee-. It is approximately 14% larger and 30% brighter.
⭐ Total Lunar Eclipse: The Earth, the Sun, and the supermoon will be aligned, and upon entering the Moon in the shadow of the Earth a total eclipse will occur. At that time the Moon will not disappear completely, but will acquire a reddish color known as the “Blood Moon .” This color is due to the light that passes through Earth’s atmosphere.
It will be necessary to wait 19 years, until January 31, 2037, so that this cosmic coincidence can be repeated and we can see this conjunction of phenomena again.
Where Do I See the Eclipse?
In Western Europe and most of Africa and South America, the show will also be partial, since there are areas where you will not be able to see the eclipse.
The spectators of the west coast of the USA will be the most fortunate and will be able to see this phenomenon in all its fullness.
The release of the Superluna from ‘blue blood’ on the morning of the 31st will also be seen in the Middle East, Asia, Eastern Russia, Australia and New Zealand.
If for whatever reason we can not go in search of the eclipse we can always see from home with a mobile or a computer the live broadcast that NASA has scheduled on this event on its channel or the streaming that the Virtual Telescope Project will do.
Will the Moon Look Blue?
No, the Moon will not look ‘blue’. This name was a proposal of the NASA that in 1940 wanted to offer a simpler definition to refer “to the second (full moon) in a month “. Since then this phenomenon is called Blue Moon.
That the Moon looks blue is a strange but real phenomenon. Moons of this color are usually seen after a volcanic eruption.
What Can We Learn?
There is no one living who has witnessed this cosmic coincidence. That’s why scientists want to make the most of this opportunity to study our satellite.
The most interesting thing for experts is to see what happens when the surface of the Moon cools quickly.
This information will help researchers to understand the evolution of the surface of the Moon and at a practical level, can be used to find the optimal landing sites.
