From the full image link, http://www.jpl.nasa.gov/spaceimages/details.php?id=pia20051 :
"A supermassive black hole is depicted in this artist's concept, surrounded by a swirling disk of material falling onto it. The purplish ball of light above the black hole, a feature called the corona, contains highly energetic particles that generate X-ray light. If you could view the corona with your eyes, it would appear nearly invisible since we can't see its X-ray light. "
noun 1. a simplified drawing showing the appearance, structure, or workings of something; a schematic representation. "a diagram of the living room"
verb 1. represent (something) in graphic form. "the experiment is diagramed on page fourteen"
Not so bizarre use of the word diagram based on its dictionary definition.
Those are some of the best. You should also keep an eye on the Event Horizon Telescope, mentioned in that video: http://eventhorizontelescope.org/index.html
