A new telescope image showcases two entangled galaxies that will eventually merge into one millions of years from now -- and previews the eventual, similar fate of our own Milky Way galaxy.

The Gemini North telescope, located on the summit of Maunakea in Hawaii, spotted the interacting spiral galaxies about 60 million light-years away in the Virgo constellation.

At this early stage, the two galactic centers are currently 20,000 light-years apart and each galaxy has maintained its pinwheel shape. As the galaxies become more entangled, gravitational forces will lead to multiple events of intense star formation. The original structures of the galaxies will change and distort.

Observations of other galactic collisions and computer modeling have provided astronomers with more evidence that mergers of spiral galaxies create elliptical galaxies. Andromeda's halo, a large envelope of gas, extends out 1.3 million light-years from the galaxy, almost halfway to the Milky Way, and as much as 2 million light-years in other directions.
