* In the atmosphere: Neon is found in the Earth's atmosphere at a very low concentration (around 0.0018% by volume). This makes it the fifth most abundant noble gas.
* In the cosmos: Neon is produced in stars through nuclear fusion, and it's the fifth most abundant element in the universe.
* In the Earth's crust: Neon is found in trace amounts within the Earth's crust, but it's not concentrated enough to be extracted from it.
