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 ...

The Hubble constant (H₀) quantifies the current expansion rate of the Universe and underlies estimates of its age, size and fate. Determinations of H₀ rest on two broad approaches: local ...

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 ...
