Thunder Night

Thunder

Thunder is the sound caused by lightning. Depending upon the distance from and nature of the lightning, it can range from a long, low rumble to a sudden, loud crack. The sudden increase in temperature and hence pressure caused by the lightning produces rapid expansion of the air in the path of a lightning bolt. In turn, this expansion of air creates a sonic shock wave, often referred to as a "thunderclap" or "peal of thunder". The scientific study of thunder is known as brontology and the irrational fear (phobia) of thunder is called brontophobia.

Night

Night, or nighttime, is the period of darkness when the Sun is below the horizon. Daylight illuminates one side of Earth, leaving the other in darkness. The opposite of nighttime is daytime. Earth's rotation causes the appearance of sunrise and sunset. Moonlight, airglow, starlight, and light pollution dimly illuminate night. The duration of day, night, and twilight varies depending on the time of year and the observer's latitude.

Midnight blue

Midnight blue is a dark shade of blue named for its resemblance to the apparently blue color of a moonlit night sky around a full moon. Midnight blue is identifiably blue to the eye in sunlight or full-spectrum light, but can appear black under certain more limited spectra sometimes found in artificial lighting. It is similar to navy, which is also a dark blue.
