Causes and magic of aurora

During great magnetic storms, another type of red aurora can occur at altitudes as high as 180 to 240 miles this type of aurora can be attributed to another excited state of atomic oxygen, and can be very spectacular and widespread. How do we know what causes auroras in 1895, a norwegian physicist named kristian birkeland addressed the queston of what causes auroras birkeland believed that auroras were caused by electrons from the sun that interacted with the earth's magnetic field.

causes and magic of aurora What causes the aurora borealis by larry gedney and vladimir degen d uring the early 19th century, some of the best scientific minds of the period believed that the aurora was caused by the reflection of sunlight from tiny ice crystals suspended high in the atmosphere.

The aurora borealis is a wonderful light show, and all that’s reaching your eyes is visible light you do have to be sure that you’re careful about the conditions when you’re observing aurorae it’s best to see them under dark skies, so you might find yourself in a somewhat remote location. The aurora depends on where in the magnetosphere the electrons came from and on what caused them to precipitate into the atmosphere dramatically different auroral shapes can be seen in a single night where can i see the aurora auroras usually occur in ring-shaped areas centered around the magnetic poles of earth.

Auroras, the beautiful and often eerie curtains of light in the night skies of the far north and south, have been enjoyed for millennia in the northern hemisphere, they are popularly called northern lights, and officially known as aurora borealis (meaning northern dawn) in the southern. But science says that different gases in earth’s atmosphere give off different colors when they are excited oxygen gives off the green color of the aurora, for example nitrogen causes blue or red colors so today the mystery of the aurora is not so mysterious as it used to be. A magical variety of shapes and colors dance in the sky as solar wind buffets earth's magnetic field when the aurora peaked in the late 1980s, shows over churchill, manitoba, included a green ribbon and a rosy curtain.

Auroras are indicators of the connection between the earth and the sun the frequency of auroras correlates to the frequency of solar activity and the sun's 11-year cycle of activity as the process of fusion occurs inside the sun, it spews high-energy particles (ions, electrons, protons, neutrinos) and radiation in the solar wind. Legends and myths of the aurora the aurora is both beautiful and slightly uncanny in appearance, and has accordingly spawned myriad legends and myths like the magnetic fields that inspire them, the beliefs surrounding auroras are polarized between positive and negative associations, as precursors of royal births on one hand, and of war and famine on the other.

Northern lights what are northern lights the bright dancing lights of the aurora are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere the lights are seen above the magnetic poles of the northern and southern hemispheres what causes the northern lights. Northern lights can be seen in the northern or southern hemisphere, in an irregularly shaped oval centred over each magnetic pole the lights are known as 'aurora borealis' in the north and 'aurora australis' in the south. The aurora australis, or southern lights, were understood by the aboriginal australians to be the dancing of the gods the aboriginals of scandinavia, the sámi, feared and respected the aurora, and placed auroral symbols on their magic drums, believing that the northern lights had supernatural powers to resolve conflicts.

What causes the aurora the “northern lights” are caused by collisions between fast-moving particles (electrons) from space and the oxygen and nitrogen gas in our atmosphere these electrons originate in the magnetosphere, the region of space controlled by earth’s magnetic field.
