A co-worker loaned me a book in the mid-nineties (it was not new) that followed the astronomers of a non-humanoid species. The story was spread across several centuries, as the astronomers discovered and finally convinced the rest of the planet that a huge celestial body was on a collision course with their planet.
I think he said it was out of print (I know he was desperate for me to return it). Another note, the balance of power between the males and females of species varied wildly across the centuries as the species' scientific knowledge increased. I've googled this in every way I can imagine and I've come up empty.
