Astronomy & Astrophysics 101: What Is “Redshift?” - SciTechDaily

WebConverting from redshift z to velocity v measured in km/sec is easy - the formula is. v = c z , where c is the speed of light, c = 3 x 10 5 km/sec. Thus, in this example, galaxy 1970729122988102 appears to be moving away from us at 0.1 x 3 x 10^5 km/sec = 30,000 km/sec. This value is typical of the galaxy redshifts found in the SkyServer database. Web16. nov 2024 · Furthermore, redshifts (and in some cases blueshifts) were measured for these galaxies, as well as their distances. Hubble made the startling discovery that the farther away a galaxy is, the greater its redshift appears to us. This correlation is now known as Hubble's Law. It helps astronomers define the expansion of the universe. how to draw trinidad https://sportssai.com
