Since its launch on May 14 (accompanied by its sibling spacecraft Herschel), Planck has been traveling to its final orbit at the second Lagrange point of the sun-Earth system, L2, and cooling its instruments down to their operational temperature of minus 459.49 degrees Fahrenheit (minus 273.05 Celsius). This temperature is just 0.1 Celsius above absolute zero, the coldest temperature theoretically possible in our universe |
