AURORA

An aurora is a natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere). The charged particles originate in the magnetosphere and solar wind are directed by the Earth`s magnetic field into the atmosphere. Most auroras occur in a band known as the aurora zone which is typically 3 to 6 in latitudinal extent and at all local times or longitudes.
Aurora is classified as diffuse or discrete aurora. The diffuse aurora is a featureless glow in the sky which may not be visible to the naked eye even in a dark night and defines the extent of the aurora zone. Discrete aurorae are sharply defined feature within the diffuse aurora which vary in brightness from just barely visible to the naked eye to bright enough to read a newspaper at night .Discrete aurorae are usually observed only in the night sky because they are not as bright as the sunlit sky .
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 Pierre Gassendi in 1621.Its southern counterpart , the aurora australis (or the south lights), has almost identical features to the aurora borealis and changes simultaneously with the changes in the northern auroral zone and is visible from high southern latitudes in Antarctica , South America and Australia.

GOSSIP

Gossip is idle talk or rumor, especially about the personal or private affairs of others; the act of is also known as dishing or tattling.
Gossip has been researched in terms of its evolutionary psychology origins.This has found gossip to be an important means by which people can monitor cooperative reputations and so maintain widespread indirect reciprocity.[3] Indirect reciprocity is a social interaction in which one actor helps another and is then benefited by a third party. Gossip has also been identified by Robin Dunbar, an evolutionary biologist, as aiding social bonding in large groups.
Social media has also provided a much faster way to share gossip. In only a matter of minutes, harmful gossip and rumors can spread online from one place in the world to another.
The term is sometimes used to specifically refer to the spreading of "dirt" and misinformation, as (for example) through excited discussion of scandals. Some newspapers carry "gossip columns" which detail the social and personal lives of celebrities or of élite members of certain communities.
