The aurora borealis or aurora australis (northern or southern lights).
Sheets and waves of vibrant light caused by charged solar particles igniting gases in Earth's atmosphere. They are typically visible at northern latitudes, and sometimes (during heavy solar activity) into the mid-latitudes of the United States and elsewhere. In-depth look at the aurora
A faint visual phenomenon associated with geomagnetic activity, occurring mainly in the high-latitude night sky. Typical auroras occur 100 to 250 km above the ground as high speed particles from the solar wind collide with atmospheric gasses at these altitudes. When observed in the northern hemisphere this phenomena is known as the Aurora Borealis (northern lights), and when viewed in the southern hemisphere it is the Aurora Australis.
The display of "dancing" light patterns seen in areas of high latitudes - nearer the poles. Auroras are caused by magnetic storms from the sun releasing huge amounts of energy. The energy travels toward the Earth as an ionic cloud. On reaching the earth, the cloud "blows" over the poles and interacts with Earth's magnetic field. The ions interact with the ionosphere energize oxygen and nitrogen molecules which causes them to emit light. Banana belt The Antarctic Peninsula.
Bright streamers of light, ascending from the horizon towards the zenith, or luminous arcs, which are manifestations of electrical energy in the upper atmosphere. The aurora is seen in both hemispheres, in high and sometimes in medium latitudes. In the northern hemisphere it is known as Aurora Borealis, in the southern as Aurora Australis.

(plural = aurorae) The light radiated by ions and atoms in Earth's upper atmosphere, in the region of the Earth's poles. Those that occur during magnetic storms can create extremely impressive spectacles. The Aurora australis, or "Southern Lights" occur near the South Pole while the Aurora borealis, or "Northern Lights" occur near the North Pole. More about auroras...

a glow in the sky, often observed in a ring-shaped region around the magnetic poles ("auroral zone") and occasionally further equatorward. The name comes from an older one, "aurora borealis," Latin for "northern dawn," given because an aurora near the northern horizon (its usual location when seen in most of Europe) looks like the glow ofthe sky preceding sunrise. Also known as "northern lights," although it occurs both north and south of the equator. The aurora is generally caused by fast electrons from space, guided earthward by magnetic field lines, and its light comes from collisions between such electrons and the atoms of the upper atmosphere, typically 100 km (60 miles) above ground.

Some of the energy produced by these disturbances is converted into colorful visible light, which shimmers and dances. Auroras have been seen on several planets in our solar system. On Earth, auroras are also known as the 'Northern Lights' (aurora borealis) or 'Southern Lights' (aurora australis), depending on in which polar region they appear.

The Aurora Borealis occurs in the northern hemisphere and the Aurora Australis occurs in the southern hemisphere.
a luminous phenomenon in the night sky which results from a radiation emission in the upper atmosphere over middle and high latitudes
A sporadic, faint visual phenomena associated with geomagnetic activity that occurs mainly in the high-latitude night sky. Auroras occur within a band of latitudes known as the auroral oval, the location of which is dependent on geomagnetic activity. Auroras are a result of collisions between atmospheric gases and precipitating charged particles (mostly electrons) guided by the geomagnetic field from the magnetotail. Each gas (oxygen and nitrogen molecules and atoms) gives out its own particular color when bombarded, and atmospheric composition varies with altitude. The auroral altitude range is 80 to 1000 km, but typical auroras are 100 to 250 km above the ground; the color of the typical aurora is yellow-green, from a specific transitions of atomic oxygen. Auroral light from lower levels in the atmosphere is dominated by blue and red bands from spectral line of atomic oxygen. The patterns and forms of the aurora include quiescent arcs, rapidly moving rays and curtains, patches, and veils.
Auroras are undulating sheets of light in the northern sky. They are caused by gases that become excited after being hit by solar particles.
Luminous and colorful "curtains of light" typically seen in the night skies of the high northern and southern latitudes. During times of increased solar activity, they can be seen at much lower latitudes. The aurora is produced when electrons from the sun’s solar wind disturb the earth’s magnetic field and interact with molecules in the earth’s upper atmosphere. (TOP OF THE PAGE) (CLOSE WINDOW)

The glowing light display that results when a planet's magnetic field guides charged particles toward the north and south magnetic poles, where they strike the upper atmosphere and excite atoms to emit photons.
electrical particles (mainly electrons and protons) flow from the sun to the Earth (the solar wind). They are guided by the Earth's magnetic field to two oval-shaped regions around the north and south poles (actually the magnetic poles, which are a little different from the geographic poles). There they bombard the upper layers of the Earth's atmosphere and cause the oxygen and nitrogen atoms and molecules to emit light, which is the light of the aurora.

The aurora is a bright glow observed in the night sky, usually in the polar zone. For this reason some scientists call it a "polar aurora" (or "aurora polaris"). In northern latitudes, it is known as the aurora borealis (IPA ), which is named after the Roman goddess of the dawn, Aurora, and the Greek name for north wind, Boreas.
Aurora was the ancient Roman equivalent of Eos, the ancient Greek goddess of the dawn. Aurora is the Latin word for dawn.
