1. INFRARED TELESCOPES
By: Kelson, Ela, Ellie, and Jesse.

2. WHAT TYPE OF TELESCOPE YOU ARE
RESEARCHING
Infrared light is one of several types of radiation
present in the electromagnetic spectrum.
INFRARED TELESCOPE.
KELSON

3. HOW IT WORKS
• An infrared telescope is a telescope that uses
infrared light to detect celestial bodies.
ELLIE

4. WHY WE USE IT
Scientist use this telescope to measure the
different temperatures of planets, stars, and dust in
the galaxy. This telescope also lets scientists be
able to see past the proto star and where the
actual star is.
ELLIE

5. WHAT IT NEEDS TO FUNCTION
 Helium.
 Solar panel shield.
 Helium tanks.
 Aperture doors and photon shutters.
 Outer shell.
 Ejectable cover.
 Barrel Baffle.
 Focal Surface.
 Slosh Baffle.
 And many more that I don’t want to put on because there is like 100,000,000

6. PRO’S AND CON’S FOR INFRARED TELESCOPE
Pros:
• can view farther than the eye.
• the image is very very clear from far away.
• Infrared waves penetrate dust clouds in space, allowing us to see areas that emit no light.
• Cons:
• Uses tons of helium and helium is running out really fast. Cannot repair if it is space unless
they send a shuttle.
• They need huge detectors that take up tons of space.
• dry mountains, because there can’t be any water vapor to screw up the signal, and they have to
be put high up, because they have to be able to see the stars and planets.

7. EXAMPLES FOR INFRARED TELESCOPES
• The Spitzer telescope: The Spitzer telescope is NASA’s
finial space based telescope and both the Humble
telescope and the Spitzer are both included in the space
program. It is also made to detect infrared radiation.
Launch date is 25 August 2003.
• The Hubble Telescope: Launched in 1990 and is one of
the longest lasting science projects or missions. It helped
determine the age of the universe the identity of the
quasars and dark energy.
