I think we can all agree that nebulae are just pretty
by David Ng
That is: “A nebula (from Latin: “cloud”; pl. nebulae or nebulæ, with ligature or nebulas) is an interstellar cloud of dust, hydrogen, helium and other ionized gases.” (from Wikipedia)

Hey David – isn’t it – ‘nebulae’…for the plural of nebula… of course, ‘nebulas’ works just fine…I was just wondering, you know, terminology-wise…on behalf of all nebulae and their kin :)! Cheers and best wishes!
Maria, you are totally correct! My bad, and just edited to make sure we’ve got the right terminology. Cheers!
