Web2. nov 2024 · Light coming to Earth from distant stars appears red shifted, which means the light source must be moving away from us. Thus, the universe must be expanding if light … WebBecause shorter wavelengths correspond to a shift towards the blue end of the spectrum, this is called blueshift. In contrast, the light from a star moving away from us seems to shift towards longer wavelengths. As this is towards the red end of the spectrum, astronomers call it redshift. Top: the light spectrum of an object at rest.
