* No Atmosphere on the Moon: The moon has no atmosphere. This is the key to why stars don't twinkle from the lunar surface.

* Twinkling is Caused by Earth's Atmosphere: The twinkling of stars, known as scintillation, is caused by the Earth's atmosphere. As starlight passes through the different layers of air, it gets bent and refracted (like light passing through a prism). These variations in the light path cause the star to appear to flicker.

So, if you were standing on the moon, the stars would appear as steady points of light without any twinkling.
