Hubble and gaia team up to conduct the most accurate measurements to date in the 1920s, edwin hubble made the groundbreaking discovery that the universe was in a state of expansion. Using hubble and newly released data from gaia, riess’ team measured the present rate of expansion to be 73.5 kilometers (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 kilometers per second faster.
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. Using hubble and newly released data from gaia, riess' team measured the present rate of expansion to be 73.5 kilometers (45.6 miles) per second per megaparsec. this means that for every 3.3. The puzzle, called the "hubble tension," is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe’s evolution. scientists using nasa's hubble space telescope and many other telescopes consistently find a. The team compared those distances with the expansion of space as measured by the stretching of light from receding galaxies. they used these two values to calculate how fast the universe expands with time, or the hubble constant. the improved hubble constant value 45.5 miles (73.2 kilometers) per second per megaparsec. (a megaparsec equals 3.26.
