4 Ιουλ 2022 · Stars don't actually twinkle, but the light from them does, as it passes through Earth's wobbling atmosphere. Learn how factors like distance, weather and refraction affect the twinkling effect and why some stars appear to change color.
Stars appear to twinkle because their light passes through our atmosphere and is bent and distorted by varying temperatures and densities of air. Some stars appear to flicker between different colours as their light is distorted by our atmosphere, as this composite image of Rigel, Betelgeuse and Sirius shows.
15 Ιουλ 2014 · Learn about astronomical scintillation, the effect of Earth's atmosphere that makes stars appear to blink. Find out why planets and the moon don't twinkle, and read comments from readers.
24 Οκτ 2005 · In outer space, where there is no atmosphere, stars do not twinkle. This is why the Hubble Space Telescope can produce the brilliant and crisp images of the universe that we have come to know.
23 Σεπ 2022 · Stars twinkle due to atmospheric turbulence and scintillation, which distort the starlight. Learn how the effect affects astronomical observations and how to distinguish stars from planets.
9 Αυγ 2013 · Stars twinkle because of atmospheric turbulence that refracts light differently from moment to moment. Learn how astronomers try to overcome or compensate for this effect and how it affects planets and other celestial objects.
