Ask an Astrobiologist
"Where do you think philosophers fit under the astrobiology umbrella? Do you think philosophy is a key aspect of astrobiology?"
  1. Question

    Has there ever been a time when the celestial equator was aligned with the galactic plane?

    No, at least not for a very long time. I don't know why you are asking. Such "alignments" have no physical or biological significance, and are not of interest or concern to either astronomers or astrobiologists.
