Galaxies redshift
WebThe universe is expanding, carrying galaxies with it like flotsam on a fast-flowing river. This expansion also stretches the wavelength of light, which astronomers call cosmological … WebRedshift means that light that is emitted by these first stars and galaxies as visible or ultraviolet light, actually gets shifted to redder wavelengths by the time we see it here and now.

WebApr 13, 2024 · “This galaxy has a much lower mass than the galaxies discussed [by Boylan-Kolchin] but, if this kind of star formation can also happen in higher-mass galaxies at similar redshifts, it could help explain the tension with the standard cosmological model,” she says. Boylan-Kolchin isn't so sure, because this object is just 53 light-years across.
