Five Things We Didn't Know About The Universe Before This New Map

New data from the Planck telescope indicates that the universe is 13.82 Billion years old — 100 million years older than we thought.

Planck launched into space in 2009 and has been scanning the skies ever since. It reads the cosmic microwave background radiation, which is the energy signature of the Big Bang, when the universe was born.

"This light started out as a white hot glow ... it would have been blindingly bright," Charles Lawrence, U.S. Planck project scientist at NASA's Jet Propulsion Laboratory, said in a press conference today. "During 13.8 billion years the universe has expanded and this light became a very cold glow that our eyes can't see."

This cosmic microwave background radiation, or CMB, is still detectable today, and interestingly, it's not evenly spread out across the universe. There are tiny fluctuations that make it "clumpy," and that shapes the universe around us. The clumpiness was the seeds of galaxies and clusters of galaxies that we see in the universe today.

It is clumpy because of fluctuations in the temperature and density of the universe at the moment the radiation waves started moving through it. Planck is able to look back at the universe when it was just 370,000 years old — when this radiation started moving.

In the new image, above, red means a little bit warmer than average, blue means a little bit cooler, and white is just about average. These are tiny fluctuations in temperature — one hundred millionth of a degree.

"Imprinted in this light is evidence of the universe's evolution and its origin," Paul Hertz, NASA's director of astrophysics, said in a press conference. The data from Planck is a huge improvement over previous readings of the CMB, from the WMAP data — seen to the right. "It's as if we've gone from a standard TV to a high definition TV."

By studying this data we can answer deep and fundamental questions of our universe. The universe is not only a little older than we thought, it is also expanding slower. Our universe has more matter than we previously thought — both the "normal" matter that makes up our world, and the mysterious dark matter. They also discovered that there's less dark energy, the mysterious stuff that's pushing the universe apart.

Here are the five things we learned for the first time about the universe:

• It's 100 million years older than we thought at 13.82 billion years old.
• It is expanding slower than we thought: 67.15 kilometers/second/megaparsec. A megaparsec is roughly 3 million light-years.
• There's more dark matter than we thought — 26.8 percent, up from 24 percent.
• It has less dark energy than we thought: 68.3 percent, down from 71.4 percent.
• It has more "normal matter" — which is the matter that we can interact with. It's now 4.9 percent, up from 4.6 percent.
