We see alien galaxies every time we look up into the night sky with a telescope, but what might aliens on those galaxies see when they look at us? New research has just painted a new picture of what our home galaxy might look like to anyone looking in from the outside.

We also have thousands of distant galaxies that we can study to get a sense of what a galaxy like ours might look like.
