Astronomers from Australia and the US used the Keck Cosmic Web Imager to study galaxy IRAS 08339+6517 .

They found interactions between the circumgalactic medium ( CGM ) and the galaxy's radiant disc that help define a boundary.

The implications could mean that the Milky Way's long predicted future collision with the Andromeda galaxy may have already begun.
