By analyzing these far-away regions with respect to the apparent shift of position of object (compared with objects that are more distant) within these regions, they were able to deduce these new, more accurate measurements for the Milky Way galaxy.
The more massive Milky Way now means that there is more chance that we will collide with the Andromeda galaxy in the far, far future.
The NRAO article also states,
“Our Solar System is about 28,000 light-years from the Milky Way’s center. At that distance, the new observations indicate, we're moving at about 600,000 miles per hour in our Galactic orbit, up from the previous estimate of 500,000 miles per hour.”
[I don’t know about you, but I’m really dizzy having to contend with this extra rotational speed. Of course, I never liked carousels, merry-go-rounds, and other such rotating rides.]
The results of their discoveries were announced at the
213th annual meeting of the American Astronomical Society (
AAS) in Long Beach, California, U.S.A.
It was held from January 4-8, 2009, at the Long Beach Convention and Entertainment Center.
