        “Upon our return, we searched the archives to discover what progress had been made in the field of astronomy during our long absence.  Celestia had discovered Clopurnicus’ misdeeds—and appointed Tycho Bray to lead the Royal Observatory.  To our sorrow, we learned that he ordered many of Clopurnicus’ notes and books burned, and had himself made no new discoveries, although he took credit for many of his predecessor’s.  Over time, ponies grew disinterested in the night sky.  They had already mapped it, and it remained unchanging.  It had no effect on their lives, as far as they knew, and the distant planet which we had observed, the sun, and the moon were all uninhabitable and uninteresting.  Tycho Bray came to the unfortunate conclusion that there were no other inhabitable planets, save our own.
