As an infrared observatory, Spitzer collected light from regions of space that are hidden from optical telescopes, and it could detect light emitted from cooler objects.
Is the Spitzer telescope optical?
The Spitzer Telescope
The Spitzer optical design is a conventional Ritchey–Chretien two-mirror system. … The secondary mirror is mounted on a cryogenic focus mechanism, which provides high-precision motion in the axial direction and was used to focus the telescope on-orbit.
What type of telescope is the Spitzer telescope?
At its launch in 2003, NASA’s Spitzer Space Telescope was the most sensitive infrared space telescope in history. Its 16-year lifetime revolutionized our view of the cosmos. Spitzer made discoveries from inside our solar system to nearly the edge of the Universe.
What is an optical space telescope?
An optical telescope is a telescope that gathers light in the visible (or optical) part of the electromagnetic spectrum.
Is the Spitzer telescope a reflector or refractor?
The Spitzer telescope is a lightweight reflector of Ritchey-Chrétien design. It weighs less than 50 kg and is designed to operate at an extremely low temperature. The telescope has an 85 cm diameter aperture.
Where is Spitzer telescope located?
The spacecraft was built by Lockheed Martin. The mission was operated and managed by the Jet Propulsion Laboratory and the Spitzer Science Center, located on the Caltech campus in Pasadena, California.
What does Spitzer study?
Spitzer Space Telescope
In 2009, Spitzer ran out of liquid coolant and began its “warm mission,” refocusing its studies on determining how quickly our universe is stretching apart, and characterizing asteroids and the atmospheres of gas-giant planets.
What does the Spitzer telescope do?
The Spitzer Space Telescope is one of NASA’s Great Observatories, designed to observe the universe in infrared light. It was launched in 2003 with an expected lifetime of 5 years.
What is the Spitzer Space Telescope used for?
The Spitzer Space Telescope, formerly known as the Space Infrared Telescope Facility, is an infrared telescope that studies the early universe, young galaxies and forming stars, and is used to detect dust disks around stars, considered an important signpost of planetary formation.
Is the Spitzer telescope used as a remote sensing equipment?
(d) The Spitzer space telescope is used as a remote sensing equipment.
What are the types of optical telescopes?
There are three primary types of optical telescope: Refractors ( Dioptrics) which use lenses, Reflectors ( Catoptrics) which use mirrors, and Combined Lens-Mirror Systems ( Catadioptrics) which use lenses and mirrors in combination (for example the Maksutov telescope and the Schmidt camera).
How do you differentiate an optical telescope from a radio telescope?
Just as optical telescopes collect visible light, bring it to a focus, amplify it and make it available for analysis by various instruments, so do radio telescopes collect weak radio light waves, bring it to a focus, amplify it and make it available for analysis.
What are the 4 main telescopes in space?

How far is Spitzer from Earth?
NASA’s Spitzer Space Telescope will be decommissioned on the 30th of January after 16 years of studying exoplanets, our own solar system and far-off galaxies. … This is because the telescope has a very particular orbit, trailing about 158 million miles behind the Earth to keep it away from interfering heat.
