This Week's Topic:

Planck And The Young Universe

The mission of the Planck satellite is to observe the Universe of the past, seeing back in time, right after the Big Bang and a new image shows the Universe as a 'child', dating back to about 380,000 years after the Big Bang, when its temperature was similar to that of the most external layer of a star today.
