Web31. dec 2016 · 2 Answers. No, the blue and red shift of stars is not possible to detect with the naked eye. There are a couple of reasons for this. First the effect is slight: even for an object moving at thousands of km/s (way faster than stars in the milky way move), it is only a tiny change in hue. Next, since the light of stars is a mixture of many ... WebThe redshift (or blueshift) of a galaxy is the shifting of its spectral features to longer (or shorter) wavelengths primarily due to the combination of Doppler motions and the general expansion of the Universe. ... or by cross-correlating the galaxy spectrum with a template spectrum of a similar star or galaxy at known redshift.

WebMeasuring a redshift or blueshift requires four steps: 1) find the spectrum of something (usually a galaxy) that shows spectral lines. 2) from the pattern of lines, identify which line was created by which atom, ion, or molecule. 3) measure the shift of any one of those lines with respect to its expected wavelength, as measured in a laboratory ... Web'Red shift' is a key concept for astronomers. The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of …
