Telescopes We see some objects in the universe because they emit
waves of visiblelight. However, many objects, such as neutron stars
and pulsars, give out their energy as non-visibletypes of light waves,
includinginfra-red and radio waves. Only visible light and radio waves
make it to Earth. Hence there are two main types of large Earth-based
telescopes—optical telescopes, which collect visiblelight using large
mirrors, and radio telescopes, which collect radio waves. Both provide
valuableinformationabout the size, compositionand movement of
stars and galaxies. Our knowledge about the universe has been greatly
increased by the placement of telescopes into space, for example the
Hubble Space Telescope (HST). The Earth’s atmosphere absorbs and
distorts light rays from space and obscures the view from the ground
for astronomers. A telescope stationed in outer space is entirely above
the atmosphere and receives images of much greater brightness,
clarity, and detailthan do ground-based telescopes with comparable
optics.
Questions on Telescopes
1) State the name of a telescope that:
a) is Earth-based and uses mirrors
b) is in space, uses a large mirror and uses solarpower
c) detects radio waves on Earth.
2) The HubbleSpace Telescope has expanded our knowledge of the
Universe. Outlinethree ways it has achievedthis.

8. Answers
1)
A) optical telescopes, which collect visible light using large mirrors,
B) HubbleSpace Telescope (HST).
C) radio telescopes, which collect radio waves
2) Hubble Space Telescope (HST) has expanded and achieved our
knowledge of the universe by giving us images that are brighter, has
more clarity (clear), and show more detail.
