In 2003, on August 25th, NASA created the Spitzer Space Telescope (this was previously known as the Space Infrared Telescope Facility), this telescope was created in order to see infrared astronomical structual, something that the naked eye was not able to see. In 2009, the telescope ran out of liquid helium was unusable after that. Before it died, however, it discovered stars, the Double Helix Nebula, and light from extrasolar planets. Since then, other infrared telescopes helped us find new stars that are forming, nebulae, and stellar nurseries. Infrared telescopes have opened up a whole new part of the galaxy for us. Because of them, we can observe things from extreme distance, like quasars. Quasars move away from Earth, and quickly at that. Because a quasar has a large redshift, they are not visible with an optical telescope. However, we are easily able to observe them through an infrared telescope. During May of 2008, a group of international infrared astronomers proved to the population that due to dust hanging around in the galaxies, we are not able to actually see how bright a galaxy is through a telescope. In actuality, galaxies are close to twice as bright as they look. The dust just takes away a significant amount of stars and makes it into infrared light.
