Images of the Milky Way's galactic center in the mid-infrared.

Despite not knowing alot about galaxies, I was absolutely blown away by all of the defined structure in the image on the right. During department tea time this week some colleagues were talking about their favorite papers that are older than themselves. I went back to my personal favorite, Infrared Observations of the Galactic Center (Becklin+ 1968) and checked out similar papers from the time. I came across a very old image of the inner parsec region shown on the right.
