Glass in the darkness. Any of you succeed to make it look well?

I've tried quite hard for a while to figure out how to make it look good. I want a sphere of glass to shine in darkness (space with starfield) but fail to do so. Any suggestions or any tutorial I might find the solution? Thank you a lot!

    I think the problem is that the stars are going to be really tiny using raytraced reflections you may want to look at using a reflection map on the glass surface with slightly exaggerated stars. This should bring them out more and make them more noticeable. Also glass in the darkness wouldn't normally be able to be seen unless it has some light shining on it to pick up its specular settings. Its a tricky scenario.

    Well, here's an attempt.

    I've set up a sphere primitive withe the Glow shader (it's under Shader Presets> Shader Builder >
    Surface > Renderman Companion...in 4.7), a geometry shell with a glass shader and an envsphere with a NASA sky photo,. The sky photo is in jpg form, so it's not as crisp as an HDR image would be. There are no other light sources...just the headlamp/ambient.

    The sky photo is plugged into both the Diffuse and the Ambient channels on the envsphere, with the color set to white and strength at 100%.
