NASA Spots Solar Filament As Long As Fifty Earths

NASA recently released an image showing a large, dark line spread across the surface of our solar system's star.

Solar phenomena are always a treat when we get to see them.
NASA recently released an image showing a large, dark line spread across the surface of our solar system's star. 
The line is what’s referred to as a filament;  a collection of cloudy solar material held in place over the sun by the forces of magnetism. 
Filaments aren't visible to the naked eye unless images are bombarded with "extreme ultraviolet light." 
So that’s exactly what the Solar Dynamics Observatory did on October 21st. 
The unstable band of bronze seen in the image is about as long as 50 Earths lined up in a row.
