The Planck mission studies and maps the earliest light in the Universe called Cosmic Microwave Background to the greatest precision yet. The CMB originates from when the universe was a mere 370,000 years old. The image produced shows minute temperature fluctuations that correspond to regions of slightly different densities. These tiny variations in density (anisotropies) are the seeds of structure in the Universe which have since evolved, through the force of gravity, into all the galaxies and stars that we see today.
Key findings include:
- age of the universe now 13.8billion years, 100 million years older than previously thought
- universe is not expanding as fast as previously thought
- less dark energy present but more dark matter and normal matter
