'Super blue blood moon' to appear Wednesday

During the eclipse, the moon loses contact with all direct light coming from the sun but it won't go completely dark.

Robert Astalos, professor of physics, encourages the campus and community to view the full lunar eclipse on January 31.

The moon's orbit is tilted by about 5 degrees relative to the earth's orbit. However, because they are only visible from one side of the earth, seeing a lunar eclipse in totality or full view is not common. But twice in each lunar cycle, the moon does cross into our planet's orbital plane. But instead of the moon slipping between the Earth and sun, the much more common lunar eclipse takes place when the moon passes through Earth's shadow, turning the moon a dusky red. Astronomers refer to this orbital proximity as perigee - a word with Greek origins that means "close to the earth" - thus this full moon was a perigean full moon.

You will want to keep your eye on the sky on Wednesday night because you will see something spectacular. NASA informed that the next total lunar eclipse along with a supermoon will occur on January 21, 2019. The last time this combination happened globally was in 1982, but it's the first time it's been visible in North America since 1866. Australians will see another lunar eclipse in July this year, when the Earth, sun and moon come together again in flawless alignment. The light appears red because it is scattered when passing through gases in the Earth's atmosphere, he said.

"The very concept of a Super Moon is an embarrassment to everything else we call super: Supernova, Supercollider, Superman, Super Mario Bros.", he wrote. For those of us in the Northeast, it will be a partial eclipse visible in the early morning hours of January 31. Sunlight squeaks around the edges of the Earth because the atmosphere acts like a prism and bends or refracts sunlight into the shadow. We'll actually have another blue moon in March; February won't have one at all. Think of it as moon "wobble" that results in the moon getting even closer and giving us a really big super moon.

The term "blue moon" has nothing to do with color.

We are counting on the fact that he'll see it. "It is more than just regime preservation that we are concerned he will use it for", he said.

It's also a blue moon, as it's the second full moon to appear this month - a rarity, hints the phrase "once in a blue moon". "If last month's Full Moon were a 16.0 inch pizza, then this month's "Super" moon would be 16.1 inches".

The original meaning was the third full moon in a season that had four full moons (as opposed to the three full moons you'd normally expect during a season).

NASA says after this, the "super blue blood moon" won't happen again until December 2047. But that is not the definition we use today.

The best time to look out for a supermoon is shortly after sunset, when the moon is low on the horizon. The closest point in its orbit is called the perigee.

And the "blood moon" business? The first supermoon of January occurred on January 1 and the second will fall on January 31.
