A common characteristic of a nebula is its vague nature. Nebulae are vast clouds of gas and dust in space, often appearing fuzzy and diffuse when observed through telescopes, leading to their classification as "vague" structures. This vagueness can be due to their low density and the fact that they may not emit their own light but instead reflect light from nearby stars or shine faintly due to ionization. This characteristic makes them less clearly defined than solid objects in the universe, providing a sense of obscurity and nebulousness.

In contrast, the other terms do not appropriately describe the inherent qualities of nebulae. "Gruesome" typically pertains to something horrific or revolting, "passionate" involves deep emotional intensity, and "obeisance" indicates a show of deference or obedience. None of these terms relate to the physical or observational traits of nebulae in an astronomical context, reinforcing why "vague" is the most fitting characteristic.
