"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."
There is more information at the Hubble Heritage site (and a gallery of photos). Here is the link for the Egg Nebula: Egg Nebula in Polarized Light
Oh, note that the last link called "Egg Nebula" in the APOD article is a PDF file. You'll need Adobe Acrobat reader to view that page.

Great APOD. Appropriate for the time of year. Thanks.

Polarized light. We can measure it thanks to crystal filters. We can describe it mathematically. We can use it to see fish. But what it is, is a mystery--something to be glossed over.

Although I prefer my eggs poached to polarized, that is an amazing view of the nebula...
Great work!
