Yes, redshift is the phenomenon where light from objects moving away from us appears to have a longer wavelength, shifting towards the red end of the spectrum. This is a key piece of evidence supporting the expansion of the universe, as it indicates that galaxies are moving away from each other.
Yes, it is.
cons quasars have have large red shift that suggest they are far away as distant galexies some quazars with very high redshifts appear to be interacting with other galexies that have lesser redshift which would suggest that quazars have ann in trensic redshift pros its perfect evidence to show that the universe is expanding
Redshift is a phenomenon where light from distant galaxies appears redder than expected due to the expansion of the universe. It tells us that the universe is expanding and provides evidence for the Big Bang theory. By studying the redshift of galaxies, scientists can understand the rate of expansion and the age of the universe.
Furthest star is UDF 00411 with a redshift of z=6.080000 Furthest object is the galaxy(galaxy cluster?) ABELL 1835:[PSR2004] 1916 with a redshift of z=10.001750
