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
The Milky Way is the galaxy that contains our Solar System. Its name “milky” is derived from its appearance as a dim glowing band arching across the night sky in which the naked eye cannot distinguish individual stars. The term “Milky Way” is a translation of the Latin via lactea, from the Greek.From the Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within the Galaxy. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Source
