WebFor example, for a galaxy moving away from us at 10% of the speed of light, its light will be redshifted by 10%. So, for this example, the hydrogen line that was at 656 nanometers … Webz = ( 680 n m − 656.3 n m) / 656.3 n m = 0.036. Hubble's law, which says simply that a galaxy's velocity (or as is sometimes plotted, its redshift) is directly proportional to its distance, also tells us something important …

Web24 apr. 2024 · The galaxies are moving away from Earth because the fabric of space itself is expanding. While galaxies themselves are on the move — the Andromeda Galaxy and the Milky Way, for example, are on a collision course — there is an overall phenomenon of redshift happening as the universe gets bigger.
