Are there any observations of the "end" of a Spiral Arm? I am trying to map the Foundation Milky Way, and one bit of information is that Terminus is located at the "terminus" of one Spiral Arm. I take it to mean that the Spiral Arm terminates a little away from Terminus.
What characterists can I suppose this region will have? Again, I would imagine that there would be no O,B or A stars in the vicinity of Terminus except in the direction of the Spiral Arm, and that those bright stars in the Spiral Arm would be clumped together. This would mean something like a geometry of about 90 degrees [or a little less] for the angle (Center of the Milky Way) - Terminus - (bright stars of the Spiral Arm) Alberto Monteiro _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
