Grade 10: Exploring Space
Images from Space
How do people detect electromagnetic radiation from objects in space?
With optical telescopes
Optical telescopes collect visible light with a mirror or lens.
With non-optical telescopes
All forms of radiation from space can be collected from by telescopes. However, special detectors must be used to form images from radiation other than visible light.
How can people observe Earth from space?
Observations of Earth from Space (called remote sensing) are made from satellites.
