Hace 1 día · Rank the stars based on the Doppler shift that we would detect on Earth, from largest blueshift, through no shift, to largest redshift. Each diagram below shows a pair of spectra with a set of spectral lines.
Hace 1 día · How would the light we observe on Earth from a high-redshift galaxy compare to the light observed from a low-redshift galaxy? We will see the high-redshift galaxy as it was earlier in time than the low-redshift galaxy.
Hace 1 día · The dotted line indicates a redshift of zero, at which galaxies look the way they do today: right of that line predicts what will happen in the future, and left is the observable past, with higher redshifts corresponding to more distant galaxies observed as they were in the more distant past.
