How many galaxies show a red-shift

Web24 okt. 2024 · Solution 1. Your first answer is the most correct one: My first answer: "Blueshifted galaxies (e.g. Andromeda) are only seen in our local neighborhood, not far away. All distant galaxies show a redshift. At larger distances (as measured e.g. with Cepheïds) the redshift is larger. For a doppler interpretation of the redshift distant … WebWhen the astronomer, Edwin Hubble, noticed the many red shifts compared to the very few blue shifts in stars and galaxies, he realized that the universe is ...
