A Brain in Space?

exposed_craniumThe brain-like blob called PMR 1 has been nicknamed the “Exposed Cranium.” This planetary nebula, located roughly 5,000 light-years away in the Vela constellation, is host to a hot, massive dying star that is rapidly losing its mass. The nebula’s interior, mushy and red in this view, is made up primarily of ionized gas, while its cooler outer consists of glowing hydrogen molecules.

In this infrared image taken by the Spitzer Space Telescope light at wavelengths of 3.6 µm is rendered in blue, 4.5 µm in green, and 8.0 µm in red.
