Symbolism in space for tattoo?

i want to get some ideas for a tattoo and i know it has to have something to do with space. i dont want just the sun or moon, it would be nice if someone could provide some symbolism for like a specific planet or something like a black hole, a galaxy, asteroid, super nova, etc. i would normally just look up stuff like this on google but google has been acting strange for me lately. thank you!
