Other than the motion of the Earth, what else would cause parallax? Right. Thank you! |

Other than the motion of the Earth, what else would cause parallax? I see, thanks. Therefore Bradley's discovery of aberration was the final bit of needed evidence? |

Other than the motion of the Earth, what else would cause parallax? Thank you for the very informative answer. You do discuss why aberration is easier to detect than parallax, which answers another (unasked) question of mine, but the core question is not addressed: Why was Bradley trying to measure parallax if it had not been discovered yet? And if it had been discovered (or suspected), yet the Earth was supposedly stationary (because Bradley's discovery proved that it wasn't), then what would explain the parallax? |

How is celestial navigation done on a low-level? Thank you. The Apollo podcast is very informative. |

Blue-shifting as opposed to violet-shifting Thanks, Alan, this is a terrific answer. It doesn't address the question (relativistic blue-shifting), so I won't mark it as accepted, but it is extremely well-written and well-researched. This was fun to read! Thank you! |

Blue-shifting as opposed to violet-shifting Nice, thanks! This addresses the red herring, not the question, but it is a very concise way to address the colours of the sky. I wonder why we don't see the sky green, though, as green is no less dominant on the graph and our eyes are very sensitive to green. |

Blue-shifting as opposed to violet-shifting @Kitchi: So I guess an ultraviolet source would be shifted away from the blue, yet be erroneously called blueshifted. |

How distorted does the Andromeda Galaxy appear to us due to the speed of light? Thanks, Martin. |
