Can someone tell me what the old cartoon I'm thinking of is?

It was a high school in space on another planet I don't remember a lot about it but I can't even get the slightest idea where to search on the internet also the cartoon characters were brightly coloured some aliens and some human I suppose, please help me!!

The Jetsons??
That's the only thing that comes to mind.

I searched it and I came up with Galaxy High School... you can find it on Google and see picts... maybe that's it.

Was it "Lloyd in Space" ?

Galaxy high... that show rocked!

Space Cases?
