Observing space Telescopes
LO:Be able to state why we would want to observe objects in space.Be able to describe how we observe objects in space using the Hubble telescope.Be able to explain how the Hubble telescope works & be able to provide examples of objects that it has found.
TASK:Why would we want to see objects in space?
Write down your thoughts on a mini-whiteboard!
So what did you think?
• How about this for a reason why we should observe space?
TelescopesOptical telescopes have bigger lenses than your _________. The bigger the lens the more _________ the
telescope takes in. Bigger lenses can see _________ . The best optical telescopes tend to reflect the light
using _________ instead of glass lenses. Large dishes like in _________ are used to detect _________ from
space. The _________ telescope is in orbit around the Earth. An advantage of a space telescope is that it
is above the Earth’s _________ and the view doesn’t get blocked by clouds, water __________ or dust. A
disadvantage of space telescopes is that it is difficult to _________ them.

TelescopesOptical telescopes have bigger lenses than an eye does. The bigger the lens the more light the telescope takes in. Bigger lenses can see further. The best optical telescopes tend to reflect the light using mirrors instead of glass lenses. Large dishes like in Jodrell Bank are used to detect radio waves from space. The Hubble telescope is in orbit around the Earth. An advantage of a space telescope is that it is above the Earth’s atmosphere and the view doesn’t get blocked by clouds. A disadvantage of space telescopes is that it is difficult to repair them.
