Mission Assurance

  • Spitzer Space Telescope

    The Spitzer Space Telescope is the largest infrared telescope ever launched into space. Its highly sensitive instruments give a unique view of the Universe, allowing us to peer into regions of space which are hidden from optical telescopes. Many areas of space are filled with vast, dense clouds of gas and dust, which block our view. Infrared, however can penetrate these clouds, allowing us to peer into regions of star formation, the centers of galaxies, and into newly forming planetary systems. The SIRTF telescopes provide information on non-light emitting matter, which we believe may make up as much as a mind bending ninety-nine percent of the total mass of the Universe. Scientists believe there may be entire solar systems with planets orbiting objects significantly more massive than Jupiter, but which don’t have the mass required to initiate nuclear fusion required to become a star.
