Sunsets On Alien Planets

alien sunsetA simulated sunset from a foreign solar system — what a dreamy dusk. PhysOrg writes:

Professor Frederic Pont, of the University of Exeter, imagined what it might really look like if a person were able to visit another planet and to then sit quietly watching as the sun set. He used data from a camera onboard Hubble, knowledge of how the color of light changes based on chemicals it encounters, and computer modeling, to create an actual image of what a sunset on an actual planet far out in space would look like. The planet in question, exoplanet HD209458b, nicknamed Osiris, just happens to be quite large and circles its star rather closely.

Though we couldn’t technically sit on the surface of Osiris, since it doesn’t have one, the picture that Pont produced approximates what it would look like, and the results are truly beautiful. The light from Osiris’s star is white, like our own sun, but when it passes through the sodium in Osirisi’s atmosphere, red light in it is absorbed, leaving the starlight to appear blue. But then, as the sun sets, the blue light is scattered in the same way as it is here on Earth (Rayleigh scattering) causing a gradual change to green, and then to mushy dark green. And finally, due to diffraction, the bottom of the image becomes slightly flattened.

    Doesn’t beat Tattoine’s sunset.

    And just think, if the US government didn’t suck so bad, didn’t suppress technology and didn’t run off of a fiat currency, we could go to these planets and see this. In this planets case we may have to stand on our spaceship and watch, but I’m sure other planets have ground to stand on.

      No actually we won’t because that’s a fat load of wishful thinking. Space colonization is never going to happen in any meaningful way.

        I know it’s not. That’s all it was, wishful thinking… I can dream, can’t I? 😉 Some of us don’t except the false reality surrounding us. We constantly think about what it would be like if the suppression didn’t exist.

          There is no suppression, its myth and conjecture, brought about by the mindless cultural narrative of infinite technological expansion and sophistication and an environment of cheap energy that came about in the early days of fossil fuel exploitation.

            I loled. But on a seriously note, I’ve seen it personally and it’s very real. So my opinion on the matter can’t be changed. I don’t really know if your trolling me or not either, iv’e seen your posts and you don’t seem that naive. We have all seen suppression of some kind in our lives.

            Whoa! Someone lives in a fantasy world. Those words may sound good in a sentence but it doesn’t change the fact that it’s complete bullshit. “No Suppression” “It’s a myth” For fuck sake are you trying to win an award for ignorance? It’s amazing how your brain tries to justify your thoughts and point of view. I really feel sorry for you if you truly believe what you wrote here. Maybe technology isn’t your cup of tea and that’s fine, but don’t think you have it all figured out, you don’t! Give me a PO box and I’ll send you a DVD with thousands of suppressed inventions developed by companies such as GE, Westinghouse, Pratt & Whitney, etc… It would blow your mind how many wonderful inventions are suppressed on a daily basis. 

            I do admire what you wrote here. The wording you used and the delivery of the message was amazing. However, I’m going to use it as an example of how delusional one can become in this day and age. Brilliant, but delusional. You know what they say; there is a fine line between genius and insanity. 

            Best Wishes and Good Health be with you Anarchy Pony. 

  3. Where’s the Ron Paul angle? Clearly Professor Pont is ignoring him as mainstream academia is completely corrupt.
