X-ray and gamma-ray telescopes
think about the most sizzling and most hazardous questions in space. Infrared
telescopes consider the spots where stars are conceived and can investigate the
focuses of cosmic systems. Optical telescopes think about the obvious light
from space and bright telescopes examine extremely hot stars. A large number of
these kinds of light, (for example, x-ray, gamma-ray, ultraviolet, and
infrared) must be contemplated from space since they are obstructed by our

There are many space telescopes
that do not observe visible light as they are not in the visible light range
according to EM spectrum. One of them is Spitzer Space Telescopes (SST) or formerly
known as Space Infrared Telescope Facility (SIRTF), an infrared space
telescopes launched in 2003 by NASA from Cape Canaveral in Florida. It is the
fourth and last NASA Great Observatories Program. Spitzer is
intended to identify infrared radiation, which is basically warm radiation. It
is contained two noteworthy parts: “The Cryogenic Telescope Assembly, which
contains a 85 cm telescope and Spitzer’s three logical instruments. The
Spacecraft, which controls the telescope, gives energy to the instruments,
handles the logical information and speaks with Earth “(“Spitzer Space
Telescope – Mission Overview”, 2017)

It might appear like a logical
inconsistency, yet NASA’s Spitzer Space Telescope must be at the same time warm
and cool to work appropriately. Everything in the Cryogenic Telescope Assembly
should be cooled to just a couple of degrees above total zero (- 459 degrees
Fahrenheit, or – 273 degrees Celsius). This is accomplished with an installed
tank of fluid helium, or cryogen. In the interim, electronic hardware in The
Spacecraft partition needs to work close room temperature.

Spitzer’s very delicate instruments
enable researchers to look into enormous areas that are escaped optical
telescopes, including dusty stellar nurseries, the focuses of universes, and
recently shaping planetary frameworks. Spitzer’s infrared eyes likewise permits
stargazers see cooler protests in space, as fizzled stars (dark colored
diminutive people), extrasolar planets, goliath sub-atomic mists, and natural
particles that may hold the key to life on different planets.

The arranged mission time frame was
to be 2.5 years with a pre-dispatch desire that the mission could stretch out
to five or somewhat more years until the locally available fluid helium supply
was depleted. (“NASA’s Spitzer Begins Warm Mission – NASA Spitzer Space
Telescope”, 2009) Without fluid helium to cool the telescope to the low
temperatures expected to work, the vast majority of the instruments are never
again usable. Notwithstanding, the two briefest wavelength modules of the IRAC
camera are as yet operable with an indistinguishable affectability from before
the cryogen was depleted, and will keep on being utilized as a part of the
Spitzer Warm Mission. All Spitzer information, from both the essential and warm
stages, are documented at the Infrared Science Archive (IRSA).
