what is auroa borealis?

Answer 1

The Northern Lights!

The aurora is a bright glow observed in the night sky, usually in the polar zone. For this reason some scientists call it a "polar aurora" (or "aurora polaris"). In northern latitudes it is known as the aurora borealis (IPA /ɔˈɹɔɹə bɔɹiˈælɪs/), which is named after the Roman goddess of the dawn, Aurora, and the Greek name for north wind, Boreas, since in Europe especially it often appears as a reddish glow on the northern horizon as if the sun were rising from an unusual direction. The aurora borealis is also called the northern lights. The aurora borealis most often occurs from September to October and from March to April. Its southern counterpart, aurora australis, has similar properties.
