[Night Hides Not]

This thread is esoteric and nebulous.

What's this tread got to do with astronomy?

Ummm...wait a sec...I was thinking of nebula...never mind.

[Verginius Rufus]

Nebula is cognate with Greek nephele (as in Aristophanes' Nephelokokkygia, Cloud-cuckoo-land), and I presume with the Russian word nebo meaning "sky."

Is that esoteric enough?
