Aurora borealis

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 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 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 - 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 (), i. e., northern daybreak; popularly called northern lights. A luminous meteoric phenomenon, visible only at night, and supposed to be of electrical origin.

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).

The aurora borealis ("northern lights") glows above Quebec in this view from the International Space Station. The circular feature at the bottom of the image is Manicouagan, a crater than formed when an asteroid struck Earth millions of years ago.

The Aurora Borealis and Aurora Australis are seen in the northern and southern hemispheres respectively. Moon facts The Moon is the closest astronomical object to the Earth.

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.

aurora (Latin for "dawn") a glow in a planet's ionosphere caused by the interaction between the planet's magnetic field and charged particles from the Sun aurora borealis the "Northern Lights"; caused by the interaction between the solar wind, ...

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.

The aurora borealis is seen in the north of the Northern hemisphere; the aurora australis in the south of the Southern.

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 and ...

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, ...

The gases of the upper atmosphere light up with the added energy. The display can only be seen at high latitudes and is called the aurora borealis (Northern Lights) in the Northern Hemisphere and the aurora australis (Southern Lights) in the ...

So taken was he with the long nights and their spectacular aurora borealis that Marsden managed eventually to control and claim it as his own.

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.

These eruptions shoot charged particles into the solar system, some of which eventually enter the Earth's magnetic field, causing the beautiful Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights).

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.

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.
