Plasmas are a common part of the world we live in. The definition of plasma allows them to exist within an environment consisting mostly of bound atoms.
A variety of human technology creates plasmas. The type I hear plasma researchers reference most is a simple RF Plasma. This is perhaps the most direct way to use electricity to shake off the electrons from their atoms within a confined volume by using fast oscillating electromagnetic fields.
Nature also creates plasma. An Aurora is certainly included. Many less "exotic" plasma states are much more common. A fire has a low population of the ionized species, but is still a plasma.
See Wikipedia for a list of available plasmas over there..! Or have a look below for the chart which shows variation of temperature and electron density in different plasmas..!
Plasmas
A quick Googling would've provided the answer. Common examples include
Lightning..!
The Sun (from Core to Corona)
Fluorescent Lights and Neon Signs
Nebulae (Luminous Clouds in Space)
The Solar Wind
Primordial Fusion during the evolution of the Universe
Magnetic Confinement Fusion Plasmas
Inertially Confined Fusion Plasmas
Flames as Plasmas
Auroras (Northern & Southern Lights)
Interstellar Space (It's not empty... It's a plasma)
Quasars, Radiogalaxies, and Galaxies (Emit plasma radiation and microwaves)
Large Scale Structures of Galaxies (Filamentary and magnetized..!)
Dense Solid State Matter (When shocked by nuclear explosion or earthquakes which emit both visible light and radio waves)
