Decades worth of data from the Hubble Space Telescope has produced a new, more accurate measurement of the expansion rate of the universe.
The new examination of data from the 32-year-old Hubble Space Telescope attempts to identify how quickly the universe expands, and how much that expansion is accelerating through a number called the Hubble Constant (named after astronomers Edwin P. Hubble and Georges Lemaître who first attempted to measure it in 1929).
The number is a notoriously tough one to pin down because different observatories looking at different areas of the universe have produced different results. Now a new study of Hubble's most recent effort may have just found the right answer, according to a press release by NASA published Thursday.
