This week's Super Blue Blood Moon

This week's Super Blue Blood Moon

The last time the three elements combined at the same time was in 1866.

- It is also the second full moon of the month, also known as a Blue Moon, which amazingly coincides with. Since 1 January was also a full moon, that will make the supermoon on 31 January 2018 both a blue moon and a supermoon.

March also will feature two full moons during its 31 days, but there will be no full moon in February. The same applies for two new moons.

The last total lunar eclipse visible on Earth was September 28, 2015.

During the eclipse, the moon will glide into Earth's shadow, gradually turning the white disk of light to orange or red. Moon during this phase is known as super moon.

This is not prime viewing for Louisville as the moon will set just before totality starts. The full event will take over four hours and the moon will be fully eclipsed by Earth's shadow for around an hour and 16 minutes. This can happen only when the sun, the earth and the moon are perfectly aligned.

Some parts of the United States will be treated to a lunar eclipse, making this the first lunar trifecta in 150 years. While other colours in the spectrum are blocked and scattered by the atmosphere, red makes it through.

And a blood moon? But, remember, it is not a scientific term.

The moon's orbit is not perfectly circular, which means its distance from Earth varies as it goes through a cycle. The event, as described by Nasa, is a combination of three separate events which will occur at the same time - the moon's closest approach to the Earth, a full moon and a full lunar eclipse. "Most of what we can see without a telescope are points of light, but the moon is close enough that we can see it and the features on it, and notice what changes and what stays the same each night", he stated. If not you are missing out on one of the most spectacular sights you could ever hope to see.

This celestial treat - a super blue blood moon - has a lot of adjectives lined up in front of it. Let's break them down.

It's an event almost 175 years in the making.

Once in a blue moon there's a reason to get up in the middle of the night. The interval varies for different regions. The first happened on December 3, 2017, NASA said in a report.

"An eclipsed moon doesn't just disappear from view, it doesn't even appear black".

If you are into space, the moon, and rare phoneme then you are in luck!
