What Does Sunset On an Alien World Look Like? 94
The Bad Astronomer writes "Using real data from Hubble Space Telescope of a planet orbiting another star, exoplanetary scientist Frédéric Pont created a lovely image of what sunset would look like from HD209458b, nicknamed Osiris, a planet 150 light years away. The Hubble data gave information on the atmospheric absorption of this hot Jupiter planet, and, coupled with models of how the atmosphere was layered, Pont was able to create a realistic looking sunset on the planet. The big surprise: the star looks green as it sets! Sodium absorption sucks out the red colors and blue is scattered away, leaving just the green hues to get through. It's a lovely application of hard scientific knowledge."

The laws of physics work the same way there that they do here
That is a metaphysical assumption of physics, not an observed fact. We won't know that for sure until we go there.
Of course...it is probably true.
