Hubble Constant: An Expanding Universe | NASA Goddard

When the Hubble Space Telescope launched, one of its main goals was to measure the rate at which our universe is expanding. That rate is called the “Hubble Constant”—named after the astronomer Edwin Hubble, who contributed to the discovery of the universe’s expansion. 

Using the Hubble Space Telescope, astronomers have been able to measure the Hubble Constant and even found out that the expansion rate of our universe is accelerating due to a mysterious force known as dark energy.
