Check out Merope’s Reflection Nebula. Looking all pretty and the such. Wouldn’t you know it though, it’s a parasite. Totally piggybacking on the splendor of a nearby star’s light.
Reflection nebulas reflect light from a nearby star. Many small carbon grains in the nebula reflect the light. The blue color typical of reflection nebula is caused by blue light being more efficiently scattered by the carbon dust than red light. The brightness of the nebula is determined by the size and density of the reflecting grains, and by the color and brightness of the neighboring star(s). NGC 1435, pictured above, surrounds Merope (23 Tau), one of the brightest stars in the Pleiades (M45). The Pleiades nebulosity is caused by a chance encounter between an open cluster of stars and a dusty molecular cloud.
Or perhaps less negatively its cosmic synergy. The melding of two different entities into a glory more beautiful than their individual identities. Cosmic coitus. Or corporate merging. Or something.
