In the very highest layer of the atmosphere, the ionosphere, solar particles collide with oxygen and nitrogen atoms and green, blue and red light is given off.

The Ionosphere . (: your welcome .
It increases the number of particles reaching the Earth's upper atmosphere. Normally, Earth's atmosphere and magnetic field block these particles. However, near the North and South poles, the particles can enter Earth's atmosphere, where they create powerful electric currents that cause gas and molecules in the atmosphere to glow. The result is rippling sheets of light in the sky called auroras.1 word for it would be?the aurora borealis

Solar winds are caused by charged particles that are ejected into the upper atmosphere of the sun. The sun continues to make these streams of charged particles and sending them into space.
The sun is constantly releasing charged particles out into space (electrons, protons, etc). This is known as the Solar Wind. Occasionally, a solar flare or coronal mass ejection releases a significant quantity of these particles (millions or even billions of tons of them). When they impact the Earth's magnetic field, they can cause the magnetic field lines to break and reconnect, which causes the charged particles to rush towards the poles. When these particles hit the upper atmosphere, they react with the atoms and molecules of the air and cause them to glow with the characteristic colours associated with the aurora.
Earth itself is largely protected from the solar wind by its magnetic field, which deflects most of the charged particles; however some of the charged particles are trapped in the Van Allen radiation belt. XxBaby Dee

Auroras are caused by charged solar particles colliding with atoms of oxygen and nitrogen in the ionosphere, which is the highest level of the atmosphere.
Northern lights, or auroras, are caused by the collision of energetic charged particles with atoms in the high altitude atmosphere. The charged particles originate in the magnetosphere and solar wind and are directed by the Earth's magnetic field into the atmosphere.

The moon has no atmosphere, so it has no auroras. Auroras need oxygen and nitrogen atoms to emit light when they are ionized when struck by solar wind particles.

The sun ejects particles known as the solar wind. As they pass the Earth, they are drawn to the magnetic poles. The particles- mainly electrons and protons, collide with atoms of gas in the atmosphere. Energy of the collision is given off as light.
