NASA and the Department of Energy are working together to build the first space-based observatory designed to understand the nature of dark energy.

One of the most significant scientific findings in the last decade was that the expansion of the universe is accelerating. The acceleration is caused by a previously unknown dark energy that makes up approximately 70 percent of the total mass energy content of the universe. The discovery of dark energy showed that empty space is filled with a mysterious energy that increases as the universe expands. While Einstein initially proposed a cosmological constant that could explain the dark energy, it is the amount of dark energy that is difficult to understand.
