Which is the best definition of noctilucent?
Definition of noctilucent 1 [from noctilucence, after such pairs as English translucence : translucent] : bioluminescent 2 [noct- + lucent] : visible or glowing at night — see noctilucent cloud
Where does the noctilucent cloud come from?
Noctilucent cloud, rare cloud form, probably composed of ice crystals and dust from meteor smoke, that occurs at a higher altitude than any other cloud form (about 82 km [50 miles]).
When to see the noctilucent in the sky?
(of high-altitude clouds) visible during the short night of the summer.
Who was the first person to photograph the noctilucent cloud?
In the years following their discovery, the clouds were studied extensively by Otto Jesse of Germany, who was the first to photograph them, in 1887, and seems to have been the one to coin the term “noctilucent cloud”. His notes provide evidence that noctilucent clouds first appeared in 1885.

How did the noctilucent cloud get its name?
The name “noctilucent” is derived from Latin words “nocto” and “lucent,” which translates to “night shining” (A direct reference to the radiant characteristics of this cloud formation.) Noctilucent clouds are also more commonly known as night shining clouds or polar mesospheric clouds.
Which is a characteristic feature of a noctilucent cloud?
A specific feature observed in noctilucent clouds is wavy, turbulent structure. However, although being an interesting point by itself, we emphasize that our simulations are not sufficiently appropriate regarding the vertical dynamics in noctilucent clouds. Thus, our simulations offer new insight into the dynamics of noctilucent clouds.
