Planck is now officially the coolest place in the known universe with the detectors for the High Frequency Instrument now at their operating temperature of 100mK – just 0.1 degree above absolute zero. The spacecraft is also nearly at its destination, with the final maneuvering burn made to set it in orbit around the L2 point, 1.5 million kilometers from Earth.

Science observations coming soon!
