Visual optical telescopes
Visual (Optical) Telescopes

  • Reflecting– uses mirrors to gather and focus light from distant objects, can be very large

  • Refracting– uses lenses to gather and

    focus light from distant objects.

X ray telescopes
X-Ray Telescopes

  • makes images using x-rays from space such as remnants of exploded stars.

  • Example: Chandra X-Ray Observatory

Gamma ray telescopes
Gamma Ray Telescopes

  • makes images using gamma rays from objects such as black holes.

  • Example: Compton Gamma Ray Observatory (decommissioned)

Infrared telescopes
Infrared Telescopes

  • detects infrared radiation from objects in space.

  • Example: Keplar , Spitzer, Webb Telescopes

Radio telescopes
Radio Telescopes

  • usually land based, detects radio waves from space, data displayed as graphs

  • Example: Arecibo, PR

Space probes
Space Probes

  • Voyager 1 and Voyager 2 space craft - collected images of Jupiter, Saturn, Uranus and Neptune and their moons.

Space probes1
Space Probes

  • Galileo – Orbited Jupiter and its moons to study their atmospheres and Jupiter’s huge storms.

Space probes2
Space Probes

  • Cassini-Huygens – orbited Saturn in 2004 then detached the Huygens probe which studied the atmosphere of Titan, Saturn’s largest moon.

Space probes3
Space Probes

  • Mars Rovers Spirit and Opportunity – confirmed water had once been present on the surface of Mars (2004)


  • provide subatomic particle energies that simulate conditions in the stars and in the early history of the universe before stars.

  • Example: CERN and the Higgs boson particle
