Every once in awhile I remember the website NASA supports. Once picture every day for about twenty five years. Galaxy M31 in the constellation Andromeda. Some two million light years across and about 200,000 light years across. The light we see now left the edge of the stars closest to us two million years ago. Scientists believe that our galaxy and M31 will begin to "collide" in about a billion years. Stars are so far apart that collisions are highly unlikely. But it will be a heck of a light show for anyone with eyes to see as M31 answers the pull of gravity. Just a little tired of politics today.
