Astronomers are revisiting their theories about how planets form after finding evidence of planets that orbit their stars opposite the star's rotation. You've seen the animation of the interstellar dust cloud turning majestically in space. Over time, the dust clouds coalesce and planets form, all following the same path around the central star. It's a lovely idea that has now been called into question given the new data. Personally, I love the image of a planet going the wrong way round its star if only because I suspect most of us feel like that defines us and our lives. Now. How can I work a retrograde planetary orbit into some character's daring escape from overwhelming odds?
