Hubble, Gaia produce most precise measure of universe’s

July 12 (UPI) –By combining the observations of the two most powerful space telescopes in orbit, scientists have achieved the most precise measurement of the Hubble constant, the universe’s expansion rate. The new measurement confirms the tension between explosion rate in the early and late universe, researchers report.

Hubble telescope images Abell 370, first BUFFALO survey

Sept. 14 (UPI) –Hubble’s BUFFALO survey, a mission to image six of the universe’s earliest galaxies, has officially begun. The space telescope recently photographed the first of the survey’s six targets, the galaxy cluster Abell 370. Abell 370 is located 4 billion light-years from Earth. It is situated in the constellation Cetus.

Hubble and Gaia Team Up to Fuel Cosmic – HubbleSite: News

Using the powerful Hubble and Gaia space telescopes, astronomers just took a big step toward finding the answer to the Hubble constant, one of the most important and long-sought numbers in all of cosmology. This number measures the rate at which the universe is expanding since the big bang, 13.8 billion years ago.

Hubble and Gaia unite to understand cosmic expansion

Using Hubble and newly released data from Gaia, Riess’ team measured the present rate of expansion to be 73.5 kilometres (45.6 miles) per second per megaparsec. This means that for every 3.3 million light-years farther away a galaxy is from us, it appears to be moving 73.5 …

Universe’s Expansion Measured with Greatest Precision Yet

Using NASA/ESA Hubble and ESA’s Gaia space telescopes, Riess et al have made the most precise measurements to date of the Universe’s expansion rate. This is calculated by gauging the distances between nearby galaxies using special types of stars called Cepheid variables as cosmic yardsticks.

How Fast is the Universe Expanding? Hubble and Gaia Team

Using both the Hubble measurements and newly released data from Gaia, Riess and his colleagues were able to refine their measurements on the present rate of expansion to 73.5 kilometers (45.6 miles) per second per megaparsec. ESA’s Gaia is currently on a five-year mission to …
