The James Webb Space Telescope's Instrument Module

JWST's Integrated Science Instrument Module (ISIM) approaches its summer 2014 destination in NASA Goddard's Space Environment Simulator (SES) chamber, as viewed from inside the Helium-cooled shroud that takes the ISIM to its flight operating temperature of ~35-40K. The flight ISIM components are enclosed within the support structure and thermal-control shroud is visible here.
