Due to my travel schedule, I am posting this one early. I hope no one minds.
Astronomical objects have a bewildering array of names. Is it M1, or The Crab Nebula, or NGC 1952, or what? Why are there so many weird names for these things?
Find out in this week’s episode of Q & BA: By Any Other Name.
Watch it right here, right now!

The question was sent in by Teri Bootelaydi:
What is the rational behind the naming and numbering of astornomical objects?!?!
I have shelves full of astronomy books and magazines, and close to a thousand sites and ‘papers’ in my Bookmarks — and not one — NOT A SINGLE ONE — explains the logic behind these labels. It’s a nightmare for an amateur to learn.
It’s as if the IAU gets together behind closed doors and laughs at us.
