What is the white in store bought eggs?

Someone posted great pictures of fertile verses non-fertile eggs. I lost the link. Anyway what is the white attached to the yolk when opening store bought eggs?

That's called the chalazia and it is in all eggs. It anchors the yolk.

Thanks always wondered about it. Sometimes it is quite big and sometimes not. I buy jumbo eggs so I guess the chalazia is bigger.

Hey, how did you draw on that egg?

I'm guessing photoshop or paint.
