Something strange is happening in the Universe: The data from the Hubble telescope that NASA is keeping an eye on

The expansion of the Universe remains a great mystery for astronomers, in fact in recent years a discrepancy has been found between the rate of expansion measured in the local universe – taken for example by Hubble and other telescopes – compared to observations independent.

Hubble data supports the idea that something strange is going on, possibly related to new physics.

“You are getting the most precise measure of the expansion rate of the universe from the gold standard of telescopes and cosmic mile markers,” said Nobel Laureate Adam Riess of the Space Telescope Science Institute (STScI) and the Johns Hopkins University it’s a statement.

One of the predictions was that the rate of expansion of the Universe would be slower than what Hubble actually sees, since when combining data from the Standard Cosmological Model of the Universe and measurements from the Planck mission of the European Space Agency, experts point out that there are a lower value for the Hubble constant: 67.5 plus or minus 0.5 kilometers per second per megaparsec, compared to 73 taken into account.

30 years ago scientists began to measure the Hubble constant to compare the Universe, but now that has changed: “I don’t really care what the expansion value is specifically, but I like to use it to learn about the Universe,” sostiene Riess.

The new Webb Space Telescope of NASA will complement what has been released el Hubble, delivering more detail over distances and sharper resolutions than Hubble can see.
