As always, there are many different ways of looking. Here is the Helix Nebula once again, this time in infrared from the Spitzer Space Telescope. Here, I've combined the five available channels of infrared data from 3.6 microns up to 24 microns.

Description
English: As always, there are many different ways of looking. Here is the Helix Nebula once again, this time in infrared from the Spitzer Space Telescope. Here, I've combined the five available channels of infrared data from 3.6 microns up to 24 microns.

The reddest channel, the 24 micron wavelength, stands in stark contrast to the rest of the image. The red glow is entirely comprised of that wavelength and the reason it looks so red is that the nucleus is nearly black at all other available wavelengths. I've read that the reason for this is probably that there is some warm dust surrounding the central star.

Some processing notes: As usual, not all channels overlapped completely, so in some areas the others had to compensate for the missing data. Around the right and lower edge is only monochrome data. Other than that, it's quite a beautiful dataset. Very few other cosmetic details to manage. You can find the data yourself at SHA. It's in the Super Mosaics category.

Red: MIPS24 (24 microns) Orange: IRAC4 (8 microns) Green: IRAC3 (5.8 microns) Cyan: IRAC2 (4.5 microns) Blue: IRAC1 (3.6 microns)

North is NOT up. It is 61° clockwise from up.
