Celestial bodies such as the Moon, planets like Venus and Jupiter, and constellations have predictable appearances in the night sky. The Moon goes through its phases approximately every 29.5 days, while planets follow specific orbits that dictate their visibility. Additionally, seasonal constellations change predictably throughout the year due to Earth's orbit around the Sun. Events like meteor showers and eclipses also occur on a regular schedule, allowing for anticipation of their appearances.
Another name for a clear night sky is a cloudless sky or starry night.
Meteors hit the Earth's atmosphere and burn up in a second or two. They streak across the night sky and are gone. Comets are farther away, and move only slowly, night by night, across the sky.
The word that is used for a group of stars in the night sky is a star cluster.
Over the long run, the Moon doesn't interfere with observations of distant stars and galaxies. On any particular night, there will be an area of the sky in which the bright moonlight (especially when full or near-full) will wash out the background stars. This is because Earth's atmosphere scatters light and diffuses the glow across the sky somewhat. But last night, or tomorrow night, the Moon was/will be in a different area of the sky and our observations won't be affected. For a professional astronomer who is planning an observation of a distant object, it's important to schedule the observation for a time when the Moon isn't in that area of the sky. Fortunately, the apparent motions of the Moon are precisely predictable.
Yes, Jupiter is currently the brightest thing in the night sky, not counting the moon.
Entirely predictable. It's so predictable that we can measure the position of the Sun in the sky to determine our position, a method we call "celestial navigation".
Lightening.
It is impossible to say. A meteor is visible in the sky somewhere on Earth every few seconds.
