In the upper mesosphere and the lower thermosphere, gas particles become electrically charged. Because these charged particles are called ions, this part of the thermosphere is called the ionosphere. In polar regions these ions radiate energy as shimmering lights called auroras, usually in latitudes above 50 degrees.
The Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermosphere, the outermost actual atmosphere. Above this layer, the exosphere has so few molecules that they can escape into space.

Auroras form in the thermosphere layer of Earth's atmosphere. This is the layer where the gases are ionized by interactions with solar radiation, allowing for the beautiful light displays of auroras to occur.
Auroras occur in the thermosphere, which is the second-highest layer of Earth's atmosphere. The thermosphere is located between the mesosphere and the exosphere, at an altitude ranging from about 80 km to 600 km above the Earth's surface.
The thermosphere is the layer of the atmosphere that lies between the mesosphere and the exosphere. It is characterized by increasing temperatures with altitude and is where the auroras occur.
Auroras occur in the thermosphere, which is the region of the atmosphere located between the mesosphere and the exosphere. This is where charged particles from the sun interact with gases in the Earth's atmosphere, creating the colorful light displays known as auroras.
The northern lights occur in the thermosphere, which is the layer of the atmosphere located between the mesosphere and exosphere. This region is where solar energy interacts with gases like oxygen and nitrogen to create the stunning light displays known as auroras.

The troposphere
The thermosphere is the layer of the atmosphere that lies between the mesosphere and the exosphere. It is characterized by increasing temperatures with altitude and is where the auroras occur.
Auroras occur primarily in the thermosphere, which is the layer of the Earth's atmosphere located between about 85 kilometers (53 miles) and 600 kilometers (373 miles) above the surface. In this layer, charged particles from the solar wind interact with the Earth's magnetic field and atmosphere, creating the stunning light displays known as auroras, or the Northern and Southern Lights.

Ionosphere of Near northern hemisphere polar regions
The northern lights occur in the thermosphere, which is the layer of the atmosphere located between the mesosphere and exosphere. This region is where solar energy interacts with gases like oxygen and nitrogen to create the stunning light displays known as auroras.
Troposphere: The layer closest to Earth where weather phenomena occur. Stratosphere: Contains the ozone layer that helps protect Earth from ultraviolet radiation. Mesosphere: The third layer where most meteors burn up upon entry into the atmosphere. Thermosphere: The outermost layer with very low density and where the auroras occur.
A planet needs a magnetic field, an atmosphere, and solar wind to have auroras. Auroras occur when charged particles from the solar wind interact with a planet's magnetic field and atmosphere, creating beautiful displays of light in the sky.
Auroras occur in the mesospere.
