aurora
A glow in the ionosphere of a planet or moon caused by the interaction between the object's magnetic field and charged particles from the Sun; "aurora" is Latin for "dawn.
Aurorae (Northern Lights)
Beautiful ribbons of light caused by the interaction of high-energy particles in the solar wind and Earth's magnetic field.
Auroral Mechanism
Auroras are now known to be caused by the collision of charged particles (e.g. electrons), found in the magnetosphere, with atoms in the Earth's upper atmosphere (at altitudes above 80 km).
Aurora Polaris
From LoveToKnow 1911
AURORA POLARIS (Aurora Borealis and Australis, Polar Light, Northern Lights), a natural phenomenon which occurs in many forms, some of great beauty.
Aurora
Aurorae are considered to be one of the seven natural wonders of the world. Occurring at high latitudes, these highly dynamical light shows, typically red and green in colour, are an electrical phenomenon visible in the night sky.

While the northern lights (Aurora Borealis) are a common feature of the Arctic and far north, viewers in Britain must be looking at exactly the right time to be lucky enough to see them.
Auroras at Non-Visible Wavelengths
The collisions of trapped charged particles with atmospheric molecules causes spectacular effects in the visible spectrum, but these excited molecules can also emit radiation in other wavelength bands.

Auroras take many forms, including luminous curtains, arcs, bands, and patches. The uniform arc is the most stable form of aurora, sometimes persisting for hours without noticeable variation.
Aurora
Also called the northern lights (or southern lights in the southern hemisphere). The aurora is a shimmering curtain of green and/or red light seen toward the north (in the northern hemisphere).
Aurora is the name given to a rumored advanced U.S. spyplane. It would be the successor to the SR-71 Blackbird. Many conspiracy theorists as well as area 51 watchers claim to have seen this thing.
Auroral Imaging
Because auroral arcs can change and evolve rapidly (especially in the brightest and most prominent displays), photography has long been used to record their details.

Aurorae are the beautiful manifestation of solar wind particles as they are bounced around a planet's magnetic field and channeled towards its poles, where they interact with gases in the upper atmosphere.
Jupiter's Aurora
These mosaics of Jupiter's night side show the Jovian aurora at approximately 45 minute intervals. The aurora is hundreds of kilometers wide and about 250 kilometers above the planet.

A rare planetary conjunction, a more rare Aurora (a red one), film in the camera, a good tripod and a kid to share it with. A tale of my lucky Astronomical night.
Aurora: A faint visual (optical) phenomenon on the earth associated with geomagnetic activity, which occurs mainly in the high-latitude night sky. Typical auroras are 100 to 250 km above the ground.
Aurora Borealis
These pictures were all taken on September 21, 2007 at the edge of Fairbanks, Alaska. The aurora stretched from the northwest horizon to the east-southeast horizon so these images capture only a section of the aurorae at a time.
AURORA.
Also known as the northern or southern lights (Aurora Borealis and Aurora Australis). Caused by the influx of charged particles from the Sun into the Earth's upper atmosphere.

Aurora: a natural display of light in the sky The temperature in the clouds of Jupiter is about minus 145 degrees Celsius (minus 234 degrees Fahrenheit). The temperature near the planet's center is much, much hotter.
Aurora Australis
also known as the southern lights, this is an atmospheric phenomenon that displays a diffuse glow in the sky in the southern hemisphere.

aurora Event which occurs when atmospheric molecules are excited by incoming charged particles from the solar wind, then emit energy as they fall back to their ground states.
Aurora
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.

aurora
The colourful displays in the upper atmosphere which occur when molecules are energized by charged particles in the solar wind. The light is emitted as the molecules release energy when they return to their original energy state.

Aurora. 'Polar lights' which occur in the Earth's upper atmosphere, caused by particles emitted by the Sun causing gas molecules in Earth's atmosphere to glow. Aurora Borealis are seen above the North Pole, Aurora Australis above the South.

A faint visual phenomenon associated with geomagnetic activity that is visible mainly in the high-latitude night sky.
Aurora
A phenomenon produced when the solar wind (made up of energized electrons and protons) disturbs the atoms and molecules in a planet's upper atmosphere.

Atmospheric event seen in the polar regions - colourful light displays occur when solar winds meet the edge of Earth's magnetic field. Known as: Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights)

Auroras:
Charged particles become trapped on the field lines of the magnetosphere. Auroras appear when trapped particles from the solar wind spiral towards a pole.
Aurorae: Aurorae (singular: aurora) occur when electrically charged particles from the solar wind interact with the magnetic field of a planet. On Earth we know them as the Northern Lights.

Aurora (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.
Auroral emissions, similar to Earth's northern lights, were observed in the polar regions of Jupiter. The auroral emissions appear to be related to material from Io that spirals along magnetic field lines to fall into Jupiter's atmosphere.

We have detected magnetic field and aurora in some other planets. It means that those planets, like ours, have an atmosphere. Our atmosphere contains 78% nitrogen, 21% oxygen and some other less common gases, like argon and carbon dioxide.
Sunspot activity produces various disturbances on earth—these include magnetic storms which manifest themselves as aurorae, interference with radio reception and electric power grids, and disturbances of the magnetic compass.
Other factors that will affect the sky, and are not typically considered, are the presence of natural forms of light pollution, such as the Gegenschein, the zodiacal light, and aurora.
