About this Image

Radio continuum emission at 3.6 cm from the inner few parsecs of our Galaxy. The bright point source in the center is Sagittarius A*, which is likely a black hole at the center of the Galaxy. The mini-spiral of emission around the point source is from ionized gas that is in systematic motion about Sgr A*.

Investigator(s):  Roberts, D.A., Yusef-Zadeh, F., Goss, W.M.
