The spitzer space telescope

It is the last mission of the NASA Great Observatories program, which saw four specialized telescopes including the Hubble Space Telescope launched between and The goal of the Great Observatories is to observe the universe in distinct wavelengths of light. Spitzer focuses on the infrared band, which normally represents heat radiation from objects. The other observatories looked at visible light Hubble, still operationalgamma-rays Compton Gamma-Ray Observatory, no longer operational and X-rays the Chandra X-Ray Observatory, still operational.

Launched into a solar orbit on Aug. The space telescope has illuminated some of the oldest galaxies in the universe, revealed a new ring around Saturn, and peered through shrouds of dust to study newborn stars and black holes.

Spitzer assisted in the discovery of planets beyond our solar system, including the detection of seven Earth-size planets The spitzer space telescope the star TRAPPIST-1, among other accomplishments.

Initially scheduled for a 2. On Earth, infrared light is used in a variety of applications, including night-vision instruments.

With its infrared vision and high sensitivity, Spitzer has contributed to the study of some of the most distant galaxies in the known universe.

The light from some of those galaxies traveled for As a result, scientists see these galaxies as they were less than million years after the birth of the universe.

Among this population of ancient galaxies was a surprise for scientists: Large, modern galaxies are thought to have formed through the gradual merger of smaller galaxies.

Each of the four Great Observatories collects light in a different wavelength range. By combining their observations of various objects and regions, scientists can gain a more complete picture of the universe.

An average galaxy like our own Milky Way, for example, radiates as much infrared light as visible wavelength light. Each part of the spectrum provides new information. Spitzer has studied some of the nearest known exoplanets to Earth, and some of the most distant exoplanets ever discovered.

Spitzer also played a key role in one of the most significant exoplanet discoveries in history: Their discovery was an enticing step in the search for life elsewhere in the universe. Results suggested the presence of fierce winds. Spitzer has found evidence for several rocky collisions in other solar systems, including one thought to involve two large asteroids.

Buckyballs are soccer-ball-shaped carbon molecules discovered in laboratory research with multiple technological applications on Earth. Spitzer has identified many more distant galaxy clusters than were previously known. An extended journey Spitzer has logged overhours of observation time.

Thousands of scientists around the world have utilized Spitzer data in their studies, and Spitzer data is cited in more than 8, published papers. The cooling system reduced excess heat from the instruments themselves that could contaminate their observations. This gave Spitzer very high sensitivity for "cold" objects.

Spitzer orbits the Sun in an Earth-trailing orbit meaning it literally trails behind Earth as the planet orbits the Sun and has continued to fall farther and farther behind Earth during its lifetime. This now poses a challenge for the spacecraft, because while it is downloading data to Earth, its solar panels do not directly face the Sun.

As a result, Spitzer must use battery power during data downloads. The batteries are then recharged between downloads.

Aug 25,  · Considered a cousin of the Hubble Space Telescope, the Spitzer Space Telescope is designed to study the early universe in infrared light. The first telescope to see light from a planet outside our solar system, Spitzer has also made important discoveries about .
