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

as asteroids, planetary nebula and

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.
