The night sky starts to get gorgeous in the fall: clearer, dryer air, less heat coming up, Orion starting to come. Winter sky is the best. You freeze, absolutely freeze, and see fifty gazillion stars, the Milky Way, all seven of the sisters.
Did a senior thesis in astrophysics in college. Went in winter to the school's telescope, in the middle of a state park, observing. No heat. Tracked U Geminorum stars, which have the amiable habit of blowing themselves up periodically. Had a professor with a quirky, wildly expansive manner and knowledge base. Sample conversation, as we're driving up there, after maybe five minutes' companionable silence:
'Wombat, in which of Beethoven's symphonies are the tympani tuned in octaves rather than fifths?'
'THE EIGHTH, Wombat, the eighth! Recall the third movement; that's where it's most obvious! And do you think it coincidence that OCTAVES appear in the EIGHTH?'
'I think not, Wombat. I THINK NOT!'
