Tarantula Nebula Spitzer 2-Color Image
Two infrared wavelengths are translated into color inside a single Spitzer view of the Tarantula Nebula.
What to observe
- Compare the red central region with the surrounding blue structures.
- Find the white areas where both mapped wavelengths are present.
Explanation
The source links the central red emission to hot gas at 4.5 micrometers and the blue regions to dust containing PAH molecules.
Color method
Red and blue distinguish two infrared signals; regions emitting both appear white.
Why it matters
Even within infrared light, different bands can trace different materials and conditions.
