It would be impossible for life to be able to exist on nebulae because it only is gases and dust which has join together and float around in space as a cloud. Also it would take a very long time for us humans to even reach one. The closest nebula to us is the **Helix Nebula**, it is about **2.5 light years in diameter and roughly 650 light years from earth.** ====== __//**Here is a picture of the Orion Nebula:**//__
