Hubble's Instruments: NICMOS - Near Infrared Camera and Multi-Object Spectrometer

The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) is an instrument providing the capability for infrared imaging and spectroscopic observations of astronomical targets. NICMOS detects light with wavelengths between 800 to 2500 nanometres. These wavelengths are infrared and thus invisible to our human eyes.

Infrared wavelengths penetrate dust clouds more than visible light does, making infrared observations useful for observing stars that would otherwise be obscured by nebulae.

NICMOS was revived by an electrical cooler installed during Servicing Mission 3B after its cooling supply ran out.

NICMOS' infrared capabilities have been largely superseded by WFC3 since that instrument's installation in 2009's Servicing Mission 4.

NICMOS is not currently in operation, though no final decision has been made about the instrument's future.
