Ok, if you're using 3D MAX, here's what you do:
1. Make direct light. That's one that goes in a straight line, and you said you've done that.
2. Go to the Modify panel on the right by clicking on the SECOND tab from the left on the panel there, go to the bottom, and open up the Atmospheres and effects panel. Click add, then click "Volume Light" and click ok. This will give you the glow.
3. To make it liiuminate the ship, you will need to add another direct light that shares the same central axis and colour as the first, but with a diameter that encompases the ship. Do not apply the volume light to this one.
That should do it - unless you're still not using MAX (hint, hint)
