Yes, most of the UV radiation from stars is blocked by Earth's atmosphere. However, some UV light does reach the surface, which is why we still receive UV radiation from the Sun. This is why we need protection like sunscreen to prevent damage from UV radiation.
Shooting stars that reach the Earth's surface are called meteorites. These are fragments of asteroids or other celestial bodies that survive the journey through Earth's atmosphere and land on the surface.
Stars themselves do not twinkle, what gives the appearance of twinkling , is the light passing through our atmosphere, different layers have different temperature's, this makes the light oscillate, much like in a heat haze you think the road has water on it but it doesn't.
Stars twinkle because of turbulence in Earth's atmosphere. As light from a star passes through the atmosphere, it gets distorted by varying air temperatures and densities. This causes the star's light to appear to flicker or twinkle when viewed from the ground.
"Shooting stars" or meteors are bits of material falling through Earth's atmosphere; they are heated to incandescence by the friction of the air. The bright trails as they are coming through the Earth's atmosphere are termed meteors, and these chunks as they are hurtling through space are called meteoroids. Large pieces that do not vaporize completely and reach the surface of the Earth are termed meteoritesMeteors
Stars appear to twinkle when viewed from Earth because of the distortion of light as it passes through Earth's atmosphere. The varying density and temperature of the air cause the light from the star to be refracted, creating the twinkling effect. This effect is not seen in space where there is no atmosphere to distort the starlight.
Stars do not twinkle from the moon because the moon does not have an atmosphere like the Earth does. The twinkling of stars is caused by the light from the stars passing through the Earth's atmosphere and being distorted by the movement of air currents. Since the moon lacks an atmosphere, the light from the stars does not twinkle when viewed from its surface.

The light passes through our atmosphere; this atmosphere changes all the time. Small changes in density will change the index of refraction, and change the direction of the light; that's what we see as twinkling.
The distortion of light from stars, causing them to twinkle, is due to the turbulence in Earth's atmosphere. As light passes through the varying densities of the atmosphere, it gets refracted in different directions, leading to the twinkling effect. Telescopes on high mountains or in space, above most of the atmosphere, can reduce this effect.
AnswerThe light comes to us from the sun, moon and stars.Without an atmosphere, there would still be light from the sun during daylight hours. The stars are not visible during the daytime because the light from the sun is scattered through the atmosphere and conceals the much fainter light of the stars, so without an atmosphere the stars would be visible both day and night. The moon reflects light to us from the sun, and would continue to do so even without an atmosphere.
Stars twinkle because of the Earth's atmosphere. The light from the star passes through different layers of the atmosphere, which causes the light to refract or bend, creating the appearance of twinkling. Factors like temperature, wind, and turbulence in the atmosphere can all contribute to the twinkling effect.
Stars appear to twinkle or flicker in the night sky due to the Earth's atmosphere causing the light from the stars to refract, creating a twinkling effect. This phenomenon is more noticeable when stars are low on the horizon, as the light passes through a greater thickness of the atmosphere. All stars can appear to "wink" or twinkle as seen from Earth.
As the light from the star travels through the turbulent atmosphere of the Earth it is refracted in a random sort of a way. This results in the observed twinkling.

Stars twinkle because of the Earth's atmosphere. As the light from a star passes through the various layers of the atmosphere, it gets refracted or bent, causing the star's brightness to fluctuate slightly. This bending of light is what creates the twinkling effect that we see from Earth.
