Humility:   Andromeda’s actual size, not accounting for the fact it is 2.5 BILLION LIGHT YEARS away, compared with the moon's 238,000 MILES away.  It contains a Trillion stars, while our galaxy contains at most a half a billion stars... And some on earth delude themselves that they are the center of Everything.

The Andromeda Galaxy is 2 million light years away from us so what we see now is how it appeared 2 million years ago. It will collide with our Milky Way in 2 billions years from now. The two galaxies are heading towards each other at a rate of 430 km/hr.

Galaxies Collide ~ Top right is M31, the Andromeda Galaxy, 2.5 million light-years away. Bright yellow star at the center is Mirach, beta star in the constellation Andromeda. Bottom left is M33, the Triangulum Galaxy, is also about 3 million light years away. Although they look far apart, M31 and M33 are engaged in a gravitational struggle. Radio astronomers have found indications of a bridge of neutral hydrogen gas that could connect the two, evidence of a closer encounter in the past…
