Meaning of 'Aurora Borealis'

January 7th Fact-of-the-Day

Red is the most common color of auroras seen in Italy where the scientist Galileo Galilei lived. In 1622 he was the first to use the Latin expression 'Aurora Borealis,' which means 'the dawn of the north,' to describe red auroras that resemble a sunrise in the north. The same phenomenon in the south is now called 'Aurora Australis.' Northern and southern auroras are now sometimes referred to collectively as 'Aurora Polaris.' ©2005 Martek International All rights reserved.
