For the last three decades, the Hubble Space Telescope has helped scientists explore some of the biggest unknowns in the universe.
Today’s Video of the Day from NASA Goddard describes how Hubble is helping to unravel the mystery of dark energy and dark matter.
With the help of other telescopes, Hubble has revealed that the expansion of the universe has been accelerating for the last few billion years. This is being driven by a phenomenon known as dark energy.
Hubble will continue to help experts gain a better understanding of the expansion rate of the universe.
