Testing the Expansion of the Universe from Other Galaxies
Your observations from our location in the Milky Way Galaxy show that the Universe is expanding. Will observers in other galaxies also detect expansion in the same way?
We will begin by viewing new data for five galaxies observed from the Milky Way Galaxy.
Select a galaxy from the menu by clicking on one of the star icons (on the left side of the Hubble plot) to see what the Hubble plots would look like for astronomers in each of the five galaxies.
Rotate and zoom the tool on the right to help visualize the relative positions of galaxies in space. Note: this does not imply that the Universe is rotating or expanding.
