Hubble Reaches New Milestone in Mystery of Universe’s Expansion Rate
Completing a nearly 30-year marathon, NASA’s Hubble Space Telescope has calibrated more than 40 “milepost markers” of space and time to help scientists measure the expansion rate of the universe to a precision of just over 1%. The measurement is about eight times more precise than Hubble’s expected capability.
NRAO’s Baseline Episode 4: Measuring the Expanding Universe
How fast is the universe expanding? We don’t know for sure.Astronomers study cosmic expansion by measuring the Hubble constant. They have measured this constant in several different ways, but some of their results don’t agree with each other. This disagreement, or tension, in the Hubble constant is a growing controversy in astronomy.
New Distance Measurements Bolster Challenge to Basic Model of Universe
A cosmic measurement technique independent of all others adds strong evidence pointing to a problem with the current theoretical model describing the composition and evolution of the Universe.
