(DESCRIPTION) 
 A yellow, orange, pink, and white spiral galaxy. 

Text, GALAXY NGC 6217. This spiral galaxy is packed full of stars. Bright blue stars and clusters of stars swirl around the center of the galaxy along a coiled set of scaffolding known as spiral arms. 

A swarm of yellow stars crowds into the center of the galaxy, forming a dense, bright core. 

But this galaxy contains a lot more than just stars. 

Broad veins of brown dust stretch along the starry spiral arms. 

Pinkish clouds of gas, called nebulae, also pepper the arms. 

At the hub of the whole thing, lurking within the galaxy's intense core, lies a massive beast that cannot be seen -- a supermassive black hole.
