Spitzer Space Telescope

Spitzer Space Telescope

Launched in 2003 this telescope orbits the Earth and is collectively developed by Caltech, NASA and JPL. The Spitzer telescope is newer compared to the Hubble and pretty advanced too but it does not operate in visible light. Instead the Spitzer is designed to exclusively sniff through space for infrared radiation thus it sees things that the normal human eye cannot. Another key factor about its position in space is that it trails Earth by about 0.1 AU so as to stay free from all sorts of atmospheric distortions.

The Spitzer is also responsible for providing evidence for a phenomenon called Hot Jupiter where gas giants burn on one side and are simultaneously cold on the other. According to a certain estimate in 2007, NASA believed that it would not last beyond 2016 but as it stands, the Spitzer continues to produce marvellous images of the cosmos till date.
