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 Borealis
the Northern Lights caused by the interaction between the solar wind, the Earth's magnetic field and the upper atmosphere; a similar effect happens in the southern hemisphere where it is known as the aurora australis.
Aurora Borealis - Light emitted by atoms and ions in the upper atmosphere near the north magnetic pole. The emission occurs when atoms and ions are struck by energetic particles from the Sun ...
Aurora borealis
The aurora is a glow observed in the night sky, usually in the polar zone. For this reason some scientists call it a "polar aurora" (or "aurora polaris").
Aurora Borealis
Also known as the northern lights, this is an atmospheric phenomenon that displays a diffuse glow in the sky in the northern hemisphere. It is caused by charged particles from the Sun as they interact with the Earth's magnetic field.
Aurora borealis on Jupiter. Three bright dots are created by magnetic flux tubes that connect to the Jovian moons Io (on the left), Ganymede (on the bottom) and Europa (also on the bottom).
Aurora borealis (), i. e., northern daybreak; popularly called northern lights. A luminous meteoric phenomenon, visible only at night, and supposed to be of electrical origin.
The Aurora Borealis and Aurora Australis are seen in the northern and southern hemispheres respectively.

AURORA POLARIS (Aurora Borealis and Australis, Polar Light, Northern Lights), a natural phenomenon which occurs in many forms, some of great beauty.
aurora borealis The aurora of northern latitudes. Also called aurora polaris, northern lights . auroral zone A roughly circular band around either geomagnetic pole above which there is a maximum of auroral activity.
northern lights (NASA SP-7, 1965) = aurora borealis. northern sky (NASA Thesaurus) That part of the sky visible from the northern hemisphere.
In northern latitudes, it is known as the aurora borealis which is named after the Roman goddess of the dawn, Aurora, and the Greek name for north wind, Boreas.
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 of the sky preceding sunrise.
Reaching Earth, these flares trigger the aurora borealis - the Northern Lights - which are those broad luminous display of lights seen floating high above Earth's Northern Hemisphere upper latitudes.
The aurora borealis is seen in the north of the Northern hemisphere; the aurora australis in the south of the Southern. [A84] ...

To add insult to injury, the solar wind -- a stream of particles which now gives us fun things such as the aurora borealis -- will become a cyclone that will make radio communication impossible and perhaps evaporate the atmosphere altogether.
Beautiful ribbons of light caused by the interaction of high-energy particles in the solar wind and Earth's magnetic field. These are common in both extreme northern (aurora borealis or northern lights) and southern latitudes (aurora ...
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)

Aurora are a luminous phenomenon of the upper atmosphere that occurs primarily in high latitudes of both hemispheres; auroras in the Northern Hemisphere are called aurora borealis, or northern lights; in the Southern Hemisphere, aurora australis, ...
For example, in North America, the aurora borealis is normally seen with any regularity only in northern Canada and Alaska.
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. The Aurora Borealis occurs in the northern hemisphere ...
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.
Inspector Kashyk spoke to Captain Kathryn Janeway of the kolyan kolyar during his apparent defection to USS Voyager in 2375, saying that he spent years gazing at them when he was a boy. Janeway compared them to the aurora borealis, ...
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.
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.
On Earth, the northern and hemisphere versions are known as aurora borealis and aurora australis, respectively. Aurorae change in brightness, shape, color, dynamics, and location in response to changes in the state of the magnetosphere.
In southern and northern polar regions the airglow is often masked by the aurora (see aurora borealis). Airglow hampers optical telescopic observations on earth by reducing the apparent contrast between stars and space.
from the outer atomic orbitals of a material, creating a sea of ions and moving charges. Stars are the most common example of plasma, but examples you may be familiar with include lightning, the hot stuff in neon signs, and the Aurora Borealis.
It is the centre of the region in the magnetosphere in which the Aurora Borealis can be seen. Its present location is 78°30' North, 69° West, near Thule in Greenland.
When the interplanetary field switches to a direction opposite the Earth's field, or when big clouds of particles enter it, the fields in the magnetotail reconnect and energy is released, producing the aurora borealis (northern lights).
