nebulas

Interstellar gas formations

Nebulas is the plural of nebula, a cloud of gas and dust in outer space.

Some nebulas are regions where stars form; others are remnants of dying stars.

The term extends to any cloudy or hazy appearance: The eye doctor noted nebulas in both corneas.

The Latin plural nebulae appears in scientific writing, but nebulas dominates in general use.
