Supermoon Lunar Eclipse To Become The First Pa…

Supermoon Lunar Eclipse To Become The First Pan-American Total Eclipse In 19 Years

“But what makes this eclipse so special is when it occurs relative to the Earth’s rotation. When the first stage of the eclipse begins, Europe and Africa will be nearing sunrise, but all of North and South America (as well as parts of Russia) will be full-on into the start of night.

As the Earth continues to turn and the Moon moves through the Earth’s shadow, the eclipse will go from penumbral to partial to total, with totality lasting for over an hour, before becoming a partial and then penumbral eclipse again.

Small portions of northern Europe and northern Asia will experience the entirety of the eclipse, but all of North and South America will get to view the entire thing. This marks the first Pan-American eclipse of the 21st century!”

On January 20/21, 2019, the Moon will slip into the Earth’s umbral shadow, creating the spectacular sight of a total lunar eclipse. The Moon will be at perigee during this event, meaning that this event will be a Supermoon eclipse, and will occur everywhere on Earth that’s experiencing night at this time. While Iceland, Ireland, the United Kingdom, and parts of Norway, Portugal, and Russia will get to see the whole thing, so will the entirety of North and South America, marking the first Pan-American eclipse of the 21st century, and the last one we’ll get until 2058!

Come get the full story of this amazing upcoming event visible to half of the Earth later this month!

This Is What Lunar Eclipses Can Teach Us About The Universe

“By looking at the sky alone, we can see the apparent, angular sizes of the Sun and Moon.

But when the Sun, Earth, and Moon all align to produce a total eclipse, it teach us how far astronomical distances truly are.

During a lunar eclipse, the Earth’s shadow falls on the Moon…”

If you wanted to learn the distances to the stars, you have to start closer: with distances and length scales you can measure before reaching for the heavens. During a total lunar eclipse, we can get there! We can not only determine the shape of the Earth, but also the Earth-Moon distance and the size of the Moon. With a little bit of care in our measurements, we can know the Earth-Sun distance and the size of the Sun, too, and this gives us a calibration point to reach for the stars. Simply by looking at relative brightness or, for more accurate results, a parallax measurement, we can learn the distance to astronomical objects beyond our Solar System.

All from measurements you can make during an eclipse, with no special equipment like a laser reflector on the Moon. Come get the scoop today!

How Rare Is The All-In-One Supermoon, Blue Moo…

How Rare Is The All-In-One Supermoon, Blue Moon, And Lunar Eclipse, Really?

“With all that, we can combine this information to arrive at how frequently we expect all of these to occur together:

  • Blue Moons make up about 3% of all full Moons,
  • Supermoons are approximately 25% of all full Moons, and
  • Total lunar eclipses occur during 5.6% of full Moons,

meaning that a Blue, Super, totally eclipsed Moon occurs with 0.042% of full Moons: once every 2,380 full Moons or so. On average, that corresponds to once every 265 years!”

On January 31st, 2018, an event that hasn’t occurred in the United States since 1866 will come to pass: a supermoon that’s also a blue moon, that’s also a total lunar eclipse. Sounds exciting, and incredibly rare! But if we look worldwide, we find that there was another such event just in 1982. This is puzzling when you consider that these events should only occur on timescales of centuries! Is this only a coincidence that we’re having so many “super blue blood moons” right now? Or is there a different explanation? You don’t know until you actually look at the science behind it, and that’s exactly what we’re doing here.

Earth holds an elite status in the solar system

It can be casual to forget the magnificence of our planet and get lost in our tight-knit everyday lives. In the advent of a lunar eclipse (January 31, 2018)  it is worth knowing that when it comes to eclipses, Earth holds a pristine status in our solar system. 

To understand why, we need to shift our perspective a little bit and ask -”How would it be like if you were on Io (one of the moons of Jupiter)?”

The most startling thing about this experience would be that the Jupiter would appear 36 times larger than the full moon (from earth).  That’s HUGE!

Also since the moons of Jupiter lies in the same plane, you would be witnessing an eclipse every 42 hours …

In addition, since Jupiter has many moons (A large family of them), you might be able to catch some your fellow moons in eclipse with the sun. Their shadows though, appearing like tiny dots on the gas giant.

Saturn and its eclipse

If we make a slight detour and end up in Saturn, this is what it looks like when Saturn occults the Sun. Although not technically an eclipse, this image was captured by Cassini with Sun behind the planet, setting the rings and its atmosphere aglow.

When people are not overwhelmed by the beauty of its rings, they notice the shadows cast by its many moons. Here is the solar eclipse of Saturn’s moon Titan:

Eclipse on our friendly neighbor – Mars

Let’s forget about all those planets that are far away, if one were make a visit to Mars which is  ~12 light minutes away, one would witness only partial eclipses because the moons of Mars are too small to block the entire sun.

Eclipses on Earth

                        One Earth, One moon, A spectacular eclipse

Eclipses on earth, on the other hand, are too surreal to be true. Our planet not only supports life but also is placed in a prime location that would cause a total solar eclipse.

And as though the entire universe wanted to amuse us even more, the moon’s orbital plane is slightly misaligned from the Earth’s orbital plane around the sun which makes an occurrence of an eclipse predictable but yet not long enough; leaving us in a state of desperation wanting for more.
