We're Not From Around Here!
We were not born here! All this time we've believed the Milky Way galaxy was our home. All this time we've assumed that we're family.
We have wondered why we are not oriented to the galaxy's ecliptic, like everybody else, but hey, it's like having blue eyes when all the relatives are brown-eyed, right? Nothing but a pesky annoyance. Well, it turns out we're adopted.
You heard it right. Some scientists are saying we're adopted. The Milky Way is not our parent galaxy. We are from another galaxy entirely, one in the process of joining with the Milky Way-- being eaten alive, as it were. We actually belong to the
Sagittarius Dwarf galaxy. This explains why, according to Steven Majewski, head of a project called 2MASS (the Two Micro All Star Survey) going on at the U. Va. and the University of Massachusetts, the Milky Way is always sideways in the night sky! That odd angle shows our Sun (and us) are influenced by some other system, and for the last 2 billion years our real parent galaxy is slowly being consumed. We exist in a trail of debris surrounding the outer edges of the Milky Way.
Who knew? And, what d'you think?
