Why is carbon referred to as the wonder element?

Carbon is one whose atoms have an almost infinite capacity for uniting with each other in chains and rings and various other configurations, and for becoming linked with atoms of other substances. 

Indeed, the incredible diversity of living creatures from bacteria to the great blue whale is largely due to this capacity of carbon. 

The complex protein molecule has carbon atoms as its basis,  as have molecules of fat, carbohydrates, enzymes, and vitamins. 

So, too, have enormous numbers of nonliving things, for carbon is not necessary a symbol of life.


What is Aurora? 

An aurora is a natural light display in the sky, predominantly seen in the high latitude regions (Aurora Borealis or the Northern Lights and Aurora Australis or the Southern Lights).

The aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. 

These collisions result in countless little bursts of light, called photons, which make up the aurora. 

Collisions with oxygen produce red and green auroras, while nitrogen produces the pink and purple colors.
