Many of the objects in our universe are
very far away from us. Special instruments
are required to study them since traveling
close enough would take a very long time.

Astronomers have lots of different
instruments that they can use to make
observations of objects in the Universe.
One of those instruments is a telescope.

There are a lot of different types of
telescopes. Two types are optical
telescopes and radio telescopes.

Optical telescopes are ones that we can
look through and see objects. These are
probably the kinds of telescopes you think
of when you hear the word telescope.

Radio telescopes are used to pick up radio
signals coming from distant objects. These
can be used to amplify signals that our
ears can’t actually hear.

We also use satellites to make
observations of other planets. We send
satellites out to orbit the objects we want
to study. They take pictures and other
readings.

In addition, scientists use infrared imaging.
Infrared is a type of light that we cannot
see with our eyes. Scientists can collect
this type of light with special instruments
to detect objects in space.

Telescopes are very important in making
observations of objects that are too far
away to see with the naked eye.

Telescopes can help us to see objects in
the Universe that are very far away with
great clarity. They give us some amazing
pictures.

You may have heard of the Hubble
Telescope which orbits Earth. It is able to
get very clear pictures because it does not
need to look through our atmosphere.

Telescopes are great for looking at
distant galaxies, stars and other objects.
Satellites can gather even more
information about objects in our solar
system.

Satellites are excellent for studying
planets in our solar system. They can orbit
planets and get excellent pictures and
other information.
http://commons.wikimedia.org/wiki/File:OC

<image>
The data that satellites send back is very
valuable to astronomers because they are
unable to travel to those planets
themselves at this point.

While telescopes give us a pretty good
view of a planet that is far away, a satellite
is much better because it can get close to
the planet.

Satellites also help us to explore Earth
and give us a lot of data to help us get
around. Anything that uses GPS is using
data collected from satellites.

Not all of the objects in the Universe can
be seen by the naked eye or by
telescopes and satellites. For these,
astronomers use infrared imaging.
http://commons.wikimedia.org/wiki/File:Infr
ared_Image_of_the_Trifid_Nebula.jpg
<image>
Infrared light is not visible by the naked
eye so you couldn’t see it through a
telescope. There are billions of objects in
space that we can’t see with our eyes.
http://commons.wikimedia.org/wiki/File:Ori

These objects emit infrared radiation
which can be detected with infrared
telescopes. This is an infrared image of
the Sombrero galaxy.

<image>
With the use of infrared, astronomers can
see objects they would never have found
otherwise and this gives them a better
understanding of how the Universe works
and why things behave the way they do.

There are many different instruments out
there that help us see what we can’t see
with just our naked eye. A microscope
helps us see things that are very small.

A telescope helps us see things that are
far away. They can be miles away or even
light years away, like when we look at
objects in the Universe.

When you look up into the sky, you are not
able to see everything that is there, but
with the help of a telescope you can see
more.

The more powerful the telescope is, the
more you are going to see, and in greater
detail. This can help you to better
understand what the Universe is made of.

Remember that telescopes will show us
objects that are far away. They make
objects easier to see, and show us more
detail about them.

They are used to look at stars, galaxies,
planets, and other objects that are far
away in our Universe.

They would not be used to look at
microbes or smaller objects in our bodies.
For that, you would need to use a
microscope.

You would never want to look at a very
bright object with a telescope because it
could hurt your eyes. Never look directly at
the Sun with a telescope.

Question F
Stem: What objects would you look at with a telescope?
Answer Choices:

Telescopes are used to see objects that
are far away while we stay on Earth. But if
we want to look at far away objects even
more up close, we can use a satellite.
http://commons.wikimedia.org/wiki/File:Ear
th_Radiation_Budget_Satellite.jpg
<image>
The satellite can travel to a planet and
orbit the planet. While it is orbiting it can
take pictures and collect more data.

The pictures that we get from satellites
can be even clearer than the images we
see through the telescopes. They are
helpful at collecting extra data for us.

Question G
Stem: What do satellites and telescopes have in common?

A. They can show us what objects faraway look like
B. They both orbit distant planets

distant objects all the time.

infrared images give us a look at objects

Infrared imaging is used primarily for
objects that are very far away and it can
be used to detect the amount of heat that
is being given off by those objects.

It is with a combination of these three
technologies (as well as many others) that
astronomers can study distant objects in
our Universe.
