Universe older than thought

Planck space telescope shows the most detailed map ever created of the cosmic microwave background.

The universe is 100 million years older than thought, according to the best-ever map of the oldest light in space.

Europe’s Planck space observatory looked back at the afterglow of the Big Bang, and those results have now added about 80 million years to the universe's age, putting it at 13.81 billion years old, according to Voice of Russia, SPACE.com

The adjustment also means space and time are expanding slightly slower than scientists thought.

These discoveries come from a new all-sky map of ancient cosmic light by the Planck probe, which has measured what's called the cosmic microwave background in greater detail than ever before.
