Best Answer

Aurora are caused by energetic particles that emanate from the Sun, these collide with molecules in the upper atmosphere. The collision pushes the molecules into higher energy states and when the molecules fall back to lower states they emit photons.

The Earth's magnetic field accelerates the solar particles and therefor the aurora are seen in a ring centered around the north and south magnetic poles.

Auroras are caused by what hitting the atmosphere?

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.


Does Mars have Auroras?

Auroras are interactions of the planet's magnetic field with the solar wind, exciting particles in the upper atmosphere. Mars' atmosphere is thin and its field weak, so such interactions as there may be would not be visible.


What produces the Auroras?

The gases of the upper atmosphere light up with the added energy. The display is called the aurora.


Is the Aurora Borealis real?

Yes, the Auroras Borealis and Australis are real colored light displays in the sky, caused by solar storm particles colliding with atoms of oxygen and nitrogen in the upper atmosphere.


What happens when particles from the solar wind enter the upper atmosphere?

I do not know for sure but I think that auroras would occur.


How big are Auroras?

Auroras have no definite size. They occur when charged particles from the Sun ionize particles in the upper atmosphere as they spiral in toward Earth's magnetic field. Auroras may be localized in one area, or may extend from horizon to horizon in the sky.


Why don't we see auroras on the moon?

The auroras we see on Earth are a result of Earth's magnetic field funneling high-energy particles from the sun into Earth's upper atmosphere, where excited electrons in gas molecules create a glow. The moon has no magnetic field and no atmosphere.


Does Mercury have Auroras?

No, it has no atmosphere.


What layer of atmosphere has the auroras?

The troposphere


How are Auroras created?

Coloured glows called auroras are common around the Earth's polar regions. They are caused by streams of particles from the sun that are attached to the magnetic poles as the particles hit the earth's upper atmosphere they cause atoms of gas to glow. Auroras can look like huge curtains hanging in the sky, slowly changing shape. Sometimes they are seen over a much wider area, particularly when the sunspot activity is high.


Where in the solar system is auoras and how can you detect it on earth?

Auroras (note spelling) are a physical phenomenon which can be observed by eye around the polar regions of any planet with a magnetic field, such as the Earth, Jupiter and Saturn. They are caused by charged particles from the Solar Wind being trapped by the magnetic field of the planet and interacting with gas molecules in the planet's atmosphere. Auroras produce wispy threads of light in the upper atmosphere which can be seen at night in polar latitudes.
