Cracking the code of cosmic distances
From the stars in our backyard to galaxies billions of light-years away, astronomers use a 'cosmic distance ladder' of methods to map the universe. Now, a global team has unified Hubble constant ...

The cosmic distance ladder is the world’s longest ruler, built to measure the universe. Since the time of the ancient Greeks, scientists have been constructing a cosmic measuring tape to measure the ...
AUSTIN, Texas — An international team of astronomers led by Fritz Benedict and Barbara McArthur of The University of Texas at Austin has used Hubble Space Telescope to solve one of the biggest ...
