To be released in a few days time is the discovery of a new `arm` to our galaxy...
The `standard` map of the Milky Way will have to be redrawn after Australian astronomers made the astonishing discovery that our spiral galaxy has an extra huge, out flung arm...!
What is quite strange is that no one noticed it before...
Hum, more news here in a few days time...
ATNF (Australia Telescope National Facility)
Basically, it`s a vast `gassy` limb comprises an arc of hydrogen
77,000 light years long and several thousand light years thick, running along the Milky Way's outermost edge and sweeping around the four main arms that swirl out from the galaxy's core.
So probably it`s either a bit that has been `broken` off an existing arm; or it could be the remnants of a dwarf galaxy that had been `eaten` by our Milky Way...
