The Egg Nebula, also known as CRL 2688, is shown on the left as it appears in
visible light with the Hubble Space Telescope's Wide Field and Planetary
Camera 2 (WFPC2) and on the right as it appears in infrared light with
Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS). Since
infrared light is invisible to humans, the NICMOS image has been assigned
colors to distinguish different wavelengths: blue corresponds to starlight
reflected by dust particles, and red corresponds to heat radiation emitted by
hot molecular hydrogen.
