Re: Astronomy
Maps detail Universe's ancient light.

A spectacular new map of the "oldest light" in the sky has just been released by the European Space Agency.
Scientists say its mottled pattern is an exquisite confirmation of our Big-Bang model for the origin and evolution of the Universe.
But there are features in the picture, they add, that are unexpected and will require ideas to be refined.
The map was assembled from 15 months' worth of data acquired by the 600m-euro (£515m) Planck space telescope.
It details what is known as the cosmic microwave background, or CMB - a faint glow of microwave radiation that pervades all of space.
Its precise configuration, visible in the new Planck data, is suggestive of a cosmos that is slightly older than previously thought - one that came into existence 13.82 billion years ago.
