What's a Juno?

I mean, it's an unusual name, isn't it? So what is a Juno? Among other things...

• The queen of the gods in Roman mythology, and notably, a fertility goddess.
• The male lead from the movie "Jenny, Juno", which also happens to be about teen pregnancy.
• An ISP that has been around since the dawn of time. Just kidding.
• An award Ellen won't be winning anytime soon - the Juno Award is a Canadian music award, equivalent to the US' Grammy Award.
• A beach in Normandy, which was used as a landing site during World War II.
• The name of seven different British warships. They're obsessive like that.
• My favorite weapon in Einhander. Unless I'm using Selene. Then it's Flash cannon all the way!
