Okay, here's a very simple way. In Modeller, under tools, choose CUSTOM > RAND-POINTS
 Choose spherical as the type, and constant. Set a high number of points - try 10000 for a test. Select the twist tool, and in the top view, centre the tool in the middle of the point sphere and drag to the left or right. You don't want to drag it too far, just enough to give a spiralling effect. Now using the stretch tool, squash the galaxy on the Y-AXIS so it is a flat, spiralling disc. If you like, use RAND-POINTS again to create a central globular cluster of stars. Select TOOLS > CUSTOM > POINTS2POLYS to turn the points into single point polygons.
In LAYOUT, give them 100% brightness, 0% diffuse, and turn glow on maximum. Make them white, and either apply an image map to the Z-AXIS of the galaxy, autosizing it (to give the galaxy random colourisation) or make it white and give it a bit of blue/yellow fractal noise. Don't forget to turn the glow on in the EFFECTS menu of LAYOUT. If you're really keen, you can use STEAMY PARTICLES to make it gaseous, but in my opinion to point option looks better.

this galaxy consists of milky way which in turn is spiral. Your answer satisfies the spiral part but what happens to the aura around it. I had to practise a lot to acheive this effect. I did the same as you have written but added a sphere around this to which I gave a planer
spiral pattern created in photoshop & gave it a y planer mapping in the transp. Further more the same object was given 2 types of fractal noises in the color texture, one in blue & the other in black to acheive the result.

thanks for the advice in turn :) I tried it and it didn't look too bad. creating TWO starry swirls, one with 50% glow and dark blue in colour, the other 100% glow and white, also makes quite a nice effect. Only problem is too many particles in one area (ie the central globular cluster) slows rendering down dramatically.
