An international team of astronomers has delivered one of the clearest measurements yet of how quickly the nearby Universe is expanding. Instead of resolving a long-standing issue, the new result makes the problem even more difficult to ignore. The collaboration includes John Blakeslee of NSF NOIRLab, which is funded by the U.S. National Science Foundation, and incorporates data from multiple NOIRLab telescopes.
