Rainbows in Space: Astronaut Sightings?

[Ender55]

Are there any circumstances, with the proper positioning, where an astronaut may witness rainbows or rainbow-ish phenomena in space? Not on the surface of another planet, mind you, but in open space. Such as in the tail of a comet, or in ice bodies or clouds of ice or other materials?

Ender55, Welcome to Physice Forums.
Just a few days ago there was a thread here in General Physics about water being ejected into space. Manned satellities do eject urine/wastewater into space. The first thing that happens is that tiny droplets of water freeze. I imagine (not positive) that if you had the sun to your back those frozen droplets would act like raindrops...and give you a rainbow in space! See:
