Milky Way Galaxy Has Mirror-Like Symmetry
By Ron Cowen, Science News May 21, 2011 | 7:00 am | Categories: Space


A new study suggests the Milky Way doesn’t need a makeover: It’s already just about perfect.

Astronomers base that assertion on their discovery of a vast section of a spiral, star-forming arm at the Milky Way’s outskirts. The finding suggests that the galaxy is a rare beauty with an uncommon symmetry — one half of the Milky Way is essentially the mirror image of the other half.
Thomas Dame and Patrick Thaddeus of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., say the structure they’ve discovered is most likely the outer extension of the Scutum-Centaurus arm from the inner galaxy. The finding suggests that Scutum-Centaurus wraps all the way around the Milky Way, making it a symmetric counterpart to the galaxy’s other major star-forming arm, Perseus.

The two arms appear to extend from opposite ends of the galaxy’s central, bar-shaped cluster of stars, each winding around the galaxy, the researchers note in an upcoming issue of Astrophysical Journal Letters.

1. We need to invade the outer stars, before the inner stars invade us.

:sarcasm:

But seriously it is the light matching gravity.

The Earth & Moon was formed by a two planet symmetry that did not work out 4 billion years ago.

2. Norma is blocking my view of the galactic center.

3. Gotta love the Golden Ratio...
...and the fractal geometry of Nature!

4. Call me a gear head. It reminds me of an engine.
Like a turbine. Burning galactic dust into star formation, waves of nuclear fire rippling outwards, followed by relative quiet for 100 million years until the next wave comes?
