Capturing the onset of galaxy rotation in the early universe



After the Big Bang came the earliest galaxies. Due to the expansion of the universe, these galaxies are receding away from us. This causes their emissions to be redshifted (shifted towards longer wavelengths). By studying these redshifts, it is possible to characterize the ‘motion’ within the galaxies as well as their distance. In a new study, astronomers have now revealed a likely rotational motion of one such distant galaxy.
