Question

What is currently happening with the Canis Major Dwarf galaxy?

A. It is expanding.
B. It is going supernova.
C. The Milky Way is absorbing it.
D. It is dying.

Answer 1

The Canis Major Dwarf galaxy is currently being absorbed by the Milky Way galaxy. The gravitational pull of the Milky Way is slowly pulling the Canis Major Dwarf galaxy apart and incorporating its stars into the Milky Way. This process is expected to continue for several billion years until the Canis Major Dwarf galaxy is completely assimilated by the Milky Way.
