Its magnificent, 5-layer sunshield will unfold, allowing it to passively cool down to temperatures cold enough to turn nitrogen into a liquid. Beyond that, it will have on-board coolant taking it down to 7 Kelvin, allowing us to observe light that’s 50 times as long as the wavelengths the human eye can see.
