What’s Next? Beyond the Solar System:
Once you have observed our own system
of planets, it’s time to really travel far from
home and look at stars and other objects.
You can observe thousands of stars with
your telescope. At first, you may think stars
are just pinpoints of light and aren’t very
interesting. But look again. There is much
information that is revealed in stars.
The first thing you will notice is that not all
stars are the same colors. See if you can find
blue, orange, yellow, white and red stars.
The color of stars sometimes can tell you
about the age of a star and the temperature
that they burn at.
Other stars to look for are multiple stars.
Very often, you can find double (or binary)
stars, stars that are very close together.
These stars orbit each other. What do you
notice about these stars? Are they
different colors? Does one seem brighter
than the other?
Almost all the stars you can see in the sky
are part of our galaxy. A galaxy is a large
grouping of stars, containing millions or
even billions of stars. Some galaxies form
a spiral (like our galaxy, the Milky Way) and
other galaxies look more like a large football
and are called elliptical galaxies. There are
many galaxies that are irregularly shaped
and are thought to have been pulled apart
because they passed too close to—or even
through—a larger galaxy.
You may be able to see the Andromeda
galaxy and several others in your telescope.
They will appear as small, fuzzy clouds.
Only very large telescope will reveal spiral or
elliptical details.
You will also be able to see some nebulas
with your scope. Nebula means cloud. Most
nebulas are clouds of gas. The two easiest
to see in the Northern Hemisphere are the
Orion nebula during the winter and the Triffid
nebula during the summer. These are large
clouds of gas in which new stars are being
born. Some nebulas are the remains of
stars exploding. These explosions are called
supernovas.
When you become an advanced observer
you can look for other types of objects such

globular clusters. And if you’re lucky,
every so often a bright comet appears
in the sky, presenting an unforgettable
sight.
The more you learn about objects in the
sky, the more you will learn to appreciate the
sights you see in your telescope. Start
a notebook and write down the observations
you make each night. Note the time and
the date.
Use a compass to make a circle, or trace
around the lid of a jar. Draw what you see

Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
