Corona

Corona is a layer of plasma (over heated gas) surrounding  the sun . Corona cannot be seen by the naked eye unless there is a total solar eclipse because the corona's glow is a million times lesser than the photosphere's but it can also be observed through a coronagraph or a coronameter which can block the light of the sun using an artificial disk so that the items surrounding the sun can be observed . Three types of corona have been observed using the coronagraph , they are :

1) The White Light Corona
2) The Emission Line Corona
3 The X-ray Corona

Zebroids

Have you ever heard of animal hybrids Like the Wholphin ( mix of a bottle nose dolphin with a killer whale) , Liger ( mix of a lion and a tiger) 
etcetera ?????, well, if u haven't, in simple language an animal hybrid is a mix of the chromosomes of an animal with another animal.
So basically ' Zebroids' are Zebra hybrids and there are many zebra hybrids like the Zebra mule, The Zonkey , The Zorse etcetera. Zebra hybrids are extremely rare and they are really very very hard to find, actually if you spot one , it's a great thing and don't forget to take a picture of it. These amazing Zebra hybrids started breeding since the 19th century and they still exist. Charles Robert Darwin, the great biologist or geologist noted a lot of zebra hybrids in his works. Here is a picture of a Zorse.
