Rays
Meteors, comets, and asteroids can hit the Moon with the force of many atomic bombs, causing debris to splash out of the craters and form gray streaks called rays.
the bright spots are just different types of dust that gets dug up by meteorites which fall. these include dust that comes from ray craters and such like that.

Young lunar craters exhibit many features, but the most prominent is "rays". These are streaks of light colored debris that spread radially outward from the impact crater. The Tycho Crater is the classic example.
They are called meteors. The particle making the bright streak of light that are known as a meteor, is a meteoroid. When it lands on the ground it is called a meteorite.
