  1. Planck instruments’ reach coldest temperature in outer space July 3, 2009 – Planck’s High Frequency Instruments reached an operational temperature of 0.1 K, said to be the coldest temperature in outer space. Planck detectors are equipped with three active, cooling systems (the final-stage cooling by a 0.1 K dilution system) working in succession to lower the operational temperature from 45 K to 0.1 K. (Left: Spacecraft’s three “V-groove”-panels for thermally isolating the payload from high temperatures and improve in radiating excess heat. Right: Planck’s Low and High Frequency Instruments (LFI and HFI, respectively) spacecraft used for imaging the sky in in six frequency channels between 100 and 857 GHz.)
