Twinkle, Twinkle
Twinkle, twinkle little star , do you
know just where you are?
Outer Space
If you are a star, you are somewhere
in outer space . What is outer space? Is it
everything far into the sky?
Yes, outer space is the huge space
that holds everything there is beyond
Earth, from the smallest speck to the
largest galaxy .
Our Universe
Universe is a word for
everything in space,
including Earth.
Outer space is huge. It is so big that
it has not stopped growing! We cannot
reach the edge of space because the ends
keep growing outward.
Imagine if you never stopped
growing!
When we think of outer space, we
usually think of everything far out in the
sky and beyond. We think of galaxies,
stars, and comets . We think of planets
and the sun. All of these things are part
of outer space.
Astronomers
Scientists who observe
and study outer space and
everything in it are called
astronomers .
Galaxies
Galaxies are made of groups of stars,
gas, and dust that are held together by
gravity .
There are billions of galaxies in
outer space. Earth is part of the
Milky Way Galaxy .
The Milky Way
Millions and Billions
A million is 1,000,000. A billion is
1,000,000,000. There are millions of
stars in some galaxies and billions of
stars in others. There are more than
billion stars in the Milky Way. It
would take 3,000 years to count them!
Spitzer Space Telescope
How do we learn about outer space?
One way is to look through powerful
telescopes, like the Spitzer Space
Telescope. The Spitzer is a satellite
orbiting in space and taking pictures for
us. Here is one of the photos it took.
