Venus phase

This picture of Venus shows the planet's phase.
Because it's low, near the horizon, the light from Venus is seen through a thick layer of atmosphere. The refraction is causing the red light to bend more than the blue.

Esta imágen de Venus muestra la fase del planeta.
Como está bajo en el horizonte, su luz es vista a través de una espesa capa de atmósfera. La refracción causa que la luz roja se curve más que la azul.
