Milky Way galaxy not a slouch after all

— Take that, Andromeda! For decades, astronomers thought when it came to the major galaxies in Earth’s cosmic neighborhood, our Milky Way was a weak sister to the larger Andromeda. Not anymore.

The Milky Way is considerably larger, bulkier and spinning faster than astronomers once thought, Andromeda’s equal.

Scientists mapped the Milky Way in a more detailed, three-dimensional way and found that it’s 15 percent larger in breadth. More important, it’s denser, with 50 percent more mass, which is like weight. The new findings were presented Monday at the American Astronomical Society’s convention in Long Beach, Calif.

A bigger Milky Way means that it could be crashing violently into the neighboring Andromeda galaxy sooner than predicted — though still billions of years from now.

Thank you LJW. More science news, less degenerate knife fight stories, please!

And this comes on the heels of the discovery that a super massive black hole lies at the galaxy's center. Really cool and exciting stuff happening, despite all the problems in the world.

So scientists admitted they had been unable to recognize the existence of half of our own galaxy, while still claiming to be knowledgeable about the creation of hundreds of thousands of other galaxies far, far away.(Job 22:12-14; Psalms 147:4-5)

"More important, it’s denser, with 50 percent more mass, which is like weight."Ow, it hurts my head when they have to print stuff like the above to compensate for our science illiteracy. Cool story otherwise.
