Infrared and Submillimetre
Further information: Infrared astronomy and Submillimetre astronomyInfrared light is of lower energy than visible light, hence is emitted by cooler objects. As such, the following can be viewed in the infrared: cool stars (including brown dwarves), nebulae, and redshifted galaxies.
