Nebulas and Galaxies have
been around since the “Big
Bang” The big bang happen
about 13.7 Billion years ago!
The “Big Bang” created
many Galaxies. Astromers
believe that there are over a
million Galaxies out there.
That’s a whole lot going on
in our universe. And in each
Galaxies there is a star.
Which blows up, and later
creates beautiful cloud like
shapes called Nebulas.
This is an
example of a
Spiral Galaxy.
This is the Galaxy
we live in. The
“Milky Way”
Nebulas are the remains
of supernovas. A
supernova is an exploding
star that can become
three times as bright as
the sun. When a
supernova occurs. All the
dust particles, gas, and
Dupree collect up.
Creating a Nebula. These
Nebulas can create many
stars like our sun. Some
stars can be brighter then
others.
This is an example of
a Supernova.
Some Nebulas
are so huge and
Gargantuan, that
they can span
across many light
years. They are
so many different
types of Nebulas
out there. And
astronomers have
found over a
dozen already.
Orion
Nebula
There are different types
of Galaxies. There is the
Spiral Galaxy which
resembles a pinwheel.
With arms spiraling out.
Elliptical Galaxies have
almost a shape that is a
Complete sphere.
Irregular Galaxies lack a
simple shape. Some
Irregular Galaxies have
just blue stars or big
clouds of gas.

There are also
different kinds of
Nebulas. A Diffuse
Nebula may be
around an extremely
hot star. Diffuse
Nebulas has so much
gas and dust it can
create over 100,000
stars like our sun. A
Planetary Nebula has
a weird appearance.
This type of Nebula
has nothing to do with
planets. An emission
Nebula is a Nebula
that can emits its own
light, This means it
can give of different
colors of light.

In the Nebulas atmosphere
there would be a lot of dust
and gas from the
supernova remains. You
would be surrounded by
hydrogen gas and Helium.
In the atmosphere of a
galaxy. There are many
stars, comets,
asteroids, and other
planets. Because there
is no oxygen, It would
be impossible to
breathe unless you
were wearing a space
suit.
The Helix nebula
in the
constellation
Aquarius is the
closest planetary
nebula to Earth. It
is 650 light-years
away and about
2.5 light years in
diameter.
The Milky Way
is said to have
many neighbors
but the closest
one is
Andromeda.
The nebula
Helix!
There is a
galaxy that
within the Milky
Way itself, The
Canis Major
Dwarf. It is our
galaxies diner.
Galaxy is
about 42,000
light years
from the
galactic center
which puts it
closer to us
than our own
galaxy!
If you went to a
nebula. It would
probably be the
best experience
you will ever have
in you life! The
Beautiful shape
clouds that can
give of amazing
colors. Who knew
that a cloud of dust
and gas can be so
Magnificent.
If we went to a new galaxy. We
might think twice before touching
ground in one of the new planets.
There could be people like us, or
AliEnS!!
OMG!
Let me ask
you this…
Do you think
life can exist
in a cloud full
of hydrogen,
Helium, and
dust…
No right?
Life cant exist
here. But yet
it can be
created.
Give me
your
BRAIN!!

Alien
have found. If there
was, we might want to
avoid contact. They
might want to conquer
us and eat our brains.
