Sporadic radiant emission from the upper atmosphere that usually occurs about the North and South magnetic poles of the Earth. Note 1: Auroras are most intense at times of intense magnetic storms caused by sunspot activity. The distribution of auroral intensity with altitude shows a pronounced maximum near 100 km above the Earth. Auroras may occasi [..]

The faint light seen before sunrise.

Illumination of the night sky, caused when electrons and protons from space collide with atoms and molecules of air in the Earth's upper atmosphere. Satellite observations usually show them as rings centred on the planet's magnetic poles. Popularly known as the Northern and Southern Lights. Various types of aurora are also found on Jupite [..]

Also known as the northern or southern lights, auroras are an atmospheric phenomenon that results in multi-coloured light shows in the night sky near the polar regions.

A glowing light display in the nighttime sky cause by excited gases in the upper atmosphere giving off light. In the Northern Hemisphere, it is called the Aurora Borealis (northern lights). In the Southern Hemisphere, it is called Aurora Australis (southern lights).

Arcs, rays or swaying curtains of green, yellow or white lights seen in latitudes of about 70o, such as Aurora Borealis or Northern Lights, and Aurora Australis or Southern Lights; caused by streams of electrified particles, emitted by the Sun, trapped in the Earth's magnetic field.

A faint visual phenomenon associated with geomagnetic activity that is visible mainly in the high-latitude night sky. Aurorae occur within a band of latitudes known as the auroral oval, the location of which is dependent on geomagnetic activity. Aurorae are a result of collisions between atmospheric gases and precipitating charged particles (mostly [..]

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. 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, aurora [..]

A glowing light display in the night-time sky caused by excited gases in the upper atmosphere. In the Southern Hemisphere it is called the Aurora Australis or Southern Lights, in the Northern Hemisphere Aurora Borealis (Northern Lights).

A glow of colored lights in the northern and southern skies, caused by electrically-charged particles streaming out of the Sun and entering the Earth’s atmosphere.

It is created by the radiant energy emission from the sun and its interaction with the earth's upper atmosphere over the middle and high latitudes. It is seen as a bright display of constantly changing light near the magnetic poles of each hemisphere.
