Or did the August 2004 issue of Astronomy (whichever one had the cover about Jupiter's moons) have an image of Sagittarius A* taken in radio in the news section, that I cannot find mentioned anywhere else in print or on the Internet? Sure, I find information about the same study, but why hasn't that very cool image shown up anywhere else? Does anyone know what's going on?

I went to go check, only to discover that I've apparently misplaced my copy (July 2004, btw). #-o

That's the link to the study described, but in Astronomy there's a different radio image where you can actually see the event horizon silhouetted against the background. I'm not sure why this wasn't lauded as a major discovery (not in optical?) or even displayed anywhere else. But Astronomy claimed it was an image and not an artist's conception.

Any of these (http://images.google.com/images?q=radio%20%22sagittarius%20a%22&hl=en&lr=&s a=N&tab=wi)?
or this one (http://antwrp.gsfc.nasa.gov/apod/ap020803.html):
"...startlingly beautiful..."?

No, it wasn't any of those. Surely somebody here reads Astronomy and knows the image I'm referring to.

I found my copy (hiding under the coffee table no less) -- and found the image from the issue in question (http://www.astronomy.com/asy/default.aspx?id=408&c=i) (p.30), it's the one in the upper-left of the set on this page (http://www.mpifr-bonn.mpg.de/staff/hfalcke/bh/sld13.html). The image is credited to NRAO in Astronomy, but I wasn't able to find it on their site, nor in the original press release (http://www.berkeley.edu/news/media/releases/2004/04/01_01_srgA.shtml).

Looks like that image was improperly credited, and computer generated.

Yep.
