What is a Telescope?
A telescope is used to collect electromagnetic
from distant objects.
telescopes collected visible
waves from distant
objects and allowed people to see much more detail
than they could observe just by looking with their eyes.
People used telescopes to look at many objects on Earth and
some people used telescopes to look at the stars and planets.
Today there are many telescopes which people use
to gather information about the Universe.
Different telescopes collect electromagnetic waves across the
whole of the electromagnetic spectrum, not just light waves.
