This illustration summarizes the almost 14-billion-year-long history of our universe. It shows the main events that occurred between the initial phase of the cosmos -- where its properties were ...

This map shows the oldest light in our universe, as detected with the greatest precision yet by the Planck mission. The ancient light, called the cosmic microwave background, was imprinted on the sky ...

This graphic illustrates the evolution of satellites designed to measure ancient light leftover from the big bang that created our universe 13.8 billion years ago. Called the cosmic microwave ...

This full-sky map from the Planck mission shows matter between Earth and the edge of the observable universe. Regions with less mass show up as lighter areas while regions with more mass are darker. ...

The Planck mission has imaged the oldest light in our universe, called the cosmic microwave background, with unprecedented precision. The results fit well with what we know about the universe and its ...

Planck's detailed map of the oldest light in our universe allowed scientists to take the most precise inventory of the universe's ingredients to date. Normal matter that makes up stars and galaxies ...

This graph shows the temperature differences in the oldest light in the universe, called the cosmic microwave background, detected by Planck at different distances apart on the sky. The curve is ...

Data from the Planck mission have allowed scientists to create a map showing matter everywhere in the universe, both light and dark. This simulation shows how it was done.

Normal, or ...
