Radio telescope- Receive radio waves emitted from objects in space, including waves from very distant stars and galaxies. Then the radio waves are used to produce images of the object from sound waves. Radio telescope receive information in any weather and during day or night.
Satellites- Are placed in orbit around earth with special instruments and telescopes that collect information from space. The information is sent back to earth where it is interpreted.
Space probes- Contains instruments to collect data and travel out of earths orbit to explore places that would be too dangerous for astronomers, the instruments that a probe contains depends on the space mission.
Spectroscopes- Collect the light from distant stars and separate that light into bands of different colors; by studying these bands, astronomers identify the element in a star
