Your nose is always visible to you,
but your brain ignores
It through a process called Unconscious
Selective Attention.

SOME INTRESTING FACT ABOUT OUR UNIVERSE.

At their farthest points,
The Earth and the moon are 252,088 miles away.
Inside that distance, you could fit every planet
The great red spot-on Jupiter,
that's about two times as big as Earth,
and Saturn is about nine times wider than Earth.
Saturn's rings are so large
that a few of the fragments within them
are as large as mountains.
But that's nothing compared to our Sun.
Just remember,
This is Earth
Earth from the moon.
This is Earth from Mars.
and here's Earth from just beyond Neptune,
four billion miles away.
But, a billion's a big number,
So, let's put that in perspective.
One million seconds equals about 11 and a half days,
whereas one billion seconds equals over 31 years.
Let's step back a bit.
Here's the size of Earth compared
with the size of our Sun.
And here's that exact same Sun
from the surface of Mars.
The total number of stars in the universe
is larger than all the grains of sand
on all the beaches of planet Earth.
And there are some stars out there
that are much, much bigger than our little, wimpy Sun.
The biggest star we know of, VY Canis Majoris,
is about 2,000 times the diameter of our Sun.
But none of those compares to the size
of a galaxy.
In fact, if you shrink the size
of our Solar System down to the size of a quarter
and shrink the Milky Way galaxy down using the same scale,
the diameter of the Milky Way
would be roughly the size of the United States.
That's because the Milky Way galaxy is huge.
which, when converted to miles,
is about 621,371,192,237,333,890 miles.
Inside of all of that is you.
You live in this tiny, tiny portion of the Milky Way.
But, even still, our galaxy is a little runt compared
with some others.
NGC 6744,
a spiral galaxy similar to our own,
is twice as wide as the Milky Way,
stretching over 200,000 light years across.
It is massive.
But let's think more.
In this picture alone, taken by the Hubble telescope,
there are thousands and thousands of galaxies,
each containing millions or billions of stars
with their own planets.
Some of the objects seen here may have formed
as many as 11 billion years ago,
just three billion years after the Big Bang.
This period of time is considered one
of the busiest star-forming periods.
And just keep this in mind,
That's a picture of a very small,
small part of the universe.
So, if you're ever feeling upset
about your favorite show being canceled
or the fact that they play Christmas music way too early,
Just remember, this is your home.
Earth.
