NASA have announced today (https://www.nasa.gov/feature/goddard/2019/mystery-of-the-universe-s-expansion-rate-widens-with-new-hubble-data) that in a new study, the Hubble Space Telescope
was used to refine the cosmic distance ladder by making more precise
measurements of the distance to 70 Cepheid variables in the LMC.
However, the results are still at odds with the measurements made by
the Planck Space observatory of the cosmic microwave background
and the expected value of the early universe's expansion.
Cosmologists refer to this growing discrepancy in various ways of
measuring the Hubble constant as the "Hubble tension".
