Optical astronomical observatory
  • The Advanced Camera for Surveys was installed in March 2002 and was expected to last approximately five years. In January 2007, an electrical short put much of the camera out of commission. It replaced the Faint Object Camera
  • The Wide Field and Planetary Camera is the "workhorse" instrument behind nearly all of the most famous Hubble pictures. As Hubble's main camera, it is used to observe just about everything
  • The Near Infrared Camera and Multi-Object Spectrometer is Hubble's heat sensor. Its sensitivity to infrared light makes it useful for observing objects obscured by interstellar gas and dust and for peering into deepest space
