An aurora is
a natural light display in the sky, especially in the high latitude regions. In
northern latitudes, the effect is known as the aurora borealis (or the northern lights), named after the Roman
goddess of dawn, Aurora, and the Greek name for the north wind, Boreas, by Galileo
in 1619. Auroras seen near the magnetic pole may be
high overhead, but from farther away, they illuminate the northern horizon as a
greenish glow or sometimes a faint red, as if the Sun were rising from an
unusual direction. Source
