What Is Redshift Of Galaxies. In 1929, edwin hubble announced that almost all galaxies appeared to be moving away from us. Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away. Evidence of this expansion comes from observing the spectrum of colors emitted by galaxies. For example, if a galaxy’s visible light, emitted at a wavelength of 500 nanometres (nm), arrives at earth at 700nm, it has been redshifted by 200nm. It lets astronomers measure a. A redshift reveals how an object in space (star/planet/galaxy) is moving compared to us. 'red shift' is a key concept for astronomers. It is attributed to the doppler. As space expands, galaxies move farther away. Redshift, displacement of the spectrum of an astronomical object toward longer (red) wavelengths. Astronomers describe the redshift of light (denoted by z) using the percentage its wavelength has changed.
