Galaxy Merger Discovery

Hey Space Placers!

Here is another discovery about galaxies and their formation.

The new research shows how galaxies like our own Milky Way Galaxy, a spiral/disk galaxy can merge with another galaxy and produce a disk galaxy in the process. Previously astronomers thought that such mergers would lead to the formation of an elliptical galaxy - that is one without spiral arms.
