    An aurora is a natural light display that shimmers in the sky. Colorful blue, red, yellow, green, and orange lights shift gently and change shape like softly blowing curtains. Auroras are only visible at night, and usually only appear in lower polar regions. Auroras are visible almost every night near the Arctic and Antarctic Circles, which are about degrees north and south of the Equator.   The observations of the colors of the aurora, either in a broader sense by looking at the overall color balance, or by detailed spectroscopic methods, can teach us much about the physical processes that cause aurora and the effects that aurora has on the upper atmosphere. The color balance tells us the altitude of aurora.

      An aurora borealis (aurora australis in the Southern Hemisphere) is precipitated by explosions on the surface of the sun, sometimes starting as solar flares, said Robert Nemiroff, an.   Science of the Northern Lights Aurora Borealis. by Pål Brekke. Sir Edmund Halley suggested the aurora was caused by magnetic liquid evaporating from pores in the polar region and moving up in the atmosphere along the magnetic field and then creating the northern lights.

    The Aurora Australis was first sighted by Europeans in the end of the 18th century, during the expeditions of Captain James Cook around Australia and the South Pacific. Cook’s crew on the HMS Endeavour recorded that ”a phenomenon appeared in the heavens in many things resembling the aurora borealis”.

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights, northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic).

Auroras are the result of disturbances in the magnetosphere caused by solar wind. The photographs are phenomenal in this book and makes me want to rush up to Alaska to see the Northern Lights in person. Of course reading some of the legends and historical accounts is extremely interesting but the real reason I was interested in this book was the mention of Northwest Airlines Flight /5(44).

The aurora borealis lights up the Arctic night skies. Also called the Northern Lights, the phenomenon is the result of beams of charged particles tracing along the Earth’s magnetic field and. "Aurora Of The Northern Lights has been awarded the Gelett Burgess Book Honor.

The aurora australis lights the Southern Hemisphere, and the aurora borealis lights the northern skies. Author Holly Hardin tells the story of an elfin maid named Mistletoe who lived in the cold, crisp land of the Northern Fey but fell in love with a young man /5(17).

The excitation state is released as auroral light. advertisement In latePalmroth published a book entitled 'Revontulibongarin opas' ('A guide for aurora borealis watchers'). Since then, studies of the aurora have progressed from observation and description by explorers, such as Sir Douglas Mawson, who recorded daily observations during the Australasian Antarctic Expedition fromto modern studies such as those conducted at the Geophysical Institute at the University of Alaska Fairbanks, and current.

Northern Lights focuses on the sky phenomena Aurora Borealis, a Northern-Hemisphere light show that occurs as charged particles enter the atmosphere and causes ionisation. Put simply, the solar winds (bursts from the sun) interact with the Earth's natural magnetism and pretty lights dance about/5.

Airglow radiation appears to arise from chemical processes, while the excitation of the aurora is generally considered to result from the transition of charged particles through the atmosphere, hence, from electrical discharges. In this chapter, the general description of auroras and the radio studies of aurora are discussed.

The excitation state is released as auroral light. In latePalmroth published a book entitled "Revontulibongarin opas" ("A guide for aurora borealis watchers").Author: Johanna Pellinen. Aurora Borealis and the Earth's Magnetic Field.

Quoting from the book Solar System Astrophysics by Brandt and Hodge (p), "The displays of Aurora Borealis and Aurora Australis have excited the imagination of men for many years.

The Aurora Borealis were named by the French scientist, Pierre Gassendi, in after the goddess of the dawn – Aurora and the god of the north wind – Boreas. Because they are so spectacular, the northern lights have given rise to many myths and legends as well as being the subject of File Size: 89KB.

Aurora, luminous phenomenon of Earth’s upper atmosphere that occurs primarily in high latitudes of both hemispheres; auroras in the Northern Hemisphere are called aurora borealis, aurora polaris, or northern lights, and in the Southern Hemisphere aurora australis, or southern lights.
