Eclipse fever has gripped North America, where many people are talking, worrying 카지노 게임 컬렉션 and obsessing 카지노 게임 컬렉션 about the April 8 .
The eclipse itself is beautiful and moving, and is an incredible opportunity to excite and involve the community in the scientific advances that eclipses have brought to us, and all the potential discoveries that we might see in the future 카지노 게임 컬렉션 including possibly discovering life on other worlds.
In a , the moon passes in between Earth and the sun, casting its . The amazing coincidence is that the moon 카지노 게임 컬렉션 about 400 times smaller than the sun 카지노 게임 컬렉션 also happens to be about 400 times closer to us than the sun, and so they appear the same size from Earth카지노 게임 컬렉션s surface.
When the sun, moon and Earth all line up, the shadow cast by the moon follows a narrow path that moves across the globe as the Earth rotates and the moon and Earth continue their orbital dances around the sun.
Palpable excitement
Most of North America will have on April 8. Totality will occur for a precious few minutes.
The excitement around the eclipse is palpable, coming from kids to adults, locals to visitors. Municipalities are worried: predicts up to a million people visiting and .

But the hype also stems from how beautiful a total eclipse can be. . Everyone should use or pinhole camera to safely watch the moon gradually cover the sun카지노 게임 컬렉션s disk.
But along the narrow path where the sun-moon-Earth alignment is perfect, we카지노 게임 컬렉션ll see a few fleeting minutes of , be able to see the and see a sunrise in all directions.
Experiencing a total eclipse allows everyone to be both an astronomer, thinking about our place in the solar system, the Milky Way and the universe, and an aesthete marvelling at the beauty of the sky.
Astrological contributions
For millennia, many societies considered eclipses as dangerous omens 카지노 게임 컬렉션 a reasonable fear given how strange it is to see darkness during the day.

As , the old Earth-centric solar system model was replaced by , which led to .
Careful measurements 카지노 게임 컬렉션 originally meant for astrology and in part because of the worry about eclipses 카지노 게임 컬렉션 contributed to our understanding of the universe and how it works.
Historical spectacles

But it was the vivid descriptions from writers like Austrian that captured the world카지노 게임 컬렉션s attention:

It was by looking at the bending of light from distant stars that Albert Einstein카지노 게임 컬렉션s theory of , bringing him to worldwide fame.
A shared passion
The global passion to witness and experience the eclipse is one that science educators can카지노 게임 컬렉션t ignore. Across the continent, astronomers and teachers are educating people on how to watch safely using pinhole cameras or .
Science educators explain to a fascinated audience how the sun, moon and Earth all must line up perfectly for a total eclipse to happen. We are all hoping for so we can see the corona and explain that it is somehow hotter than the surface of the sun.
Today, eclipses aren카지노 게임 컬렉션t necessarily studied for new discoveries. However, astronomers use a similar dimming of distant stars as of it. We카지노 게임 컬렉션ve discovered thousands of worlds, confirming that exoplanets are common. We can now during an extra-solar eclipse-like and signs of life in an exoplanet카지노 게임 컬렉션s atmosphere.
So the hype for the total solar eclipse on April 8 is worth it. For us, it isn카지노 게임 컬렉션t just sublime beauty. It is the chance to connect to huge crowds as excited as we are. It is the opportunity to link what we are seeing to the vastness of space, the millennia of history and the promise of understanding our wider universe 카지노 게임 컬렉션 all in three minutes in the moon카지노 게임 컬렉션s shadow.
