Explore big discoveries that have revolutionized our understanding of the universe.

A lot has changed in the last 50 years, especially in our understanding of the cosmos. DECODING THE UNIVERSE "Cosmos" explores the last five decades in astronomical discovery, as well as the most pressing questions cosmologists are now trying to answer. How did our vision of the universe get completely overturned in just a few decades, and what new surprises might lie just over the horizon? Since the 1970s and the launch of the Voyager missions, scientists have confirmed the existence of planets beyond our solar system, supermassive black holes, and thousands of previously unknown galaxies.


Perhaps the most important discovery of the last half century has been how much is still unknown about the universe. DECODING THE UNIVERSE "Cosmos" documents what we currently know about dark matter and dark energy, two properties that were only accepted as “real” during the last 50 years. Scientists now believe dark energy is the most powerful force in the universe.
