Check out this MWA image of the galactic plane from David Kaplan (UWM). The image of 150MHz radiation covers 80 degrees wide and has a resolution of about 5 arcminutes. At about 125million pixels its a bit large to digest, so I’ve uploaded it to Gigapan, where you can pan and zoom ala google maps. Most of the circular things are supernova remnants, the imprints of ancient supernova explosions impressed on the galaxies plasma and magnetic fields.
This is just a sneak preview of the imaging capability of this fully operational battle station.
