👉 In astronomy, "starlessness" refers to a state of complete absence or lack of stars. It is often used in contexts where there are no visible celestial bodies present, such as during periods of total darkness, or when observing a sky that is devoid of any light sources. The term can also be applied to situations in which there is an absence of stars but not necessarily all the other objects we typically associate with them, such as planets, moons, and asteroids.
