Sagittarius A East with Labels
The large white dashed ellipse represents the approximate boundary of non-thermal emission for the supernova remnant known as Sgr A East. The smaller white dashed oval represents the area, known as Sgr A West, where spiral-shaped streams of gas are falling onto the black hole at the center of the Milky Way.

Sagittarius A East Radio Image
A 20-cm radio image of Sgr A East taken by the Very Large Array. The radio emission from the central few parsecs of the Galaxy has several components, including a compact non-thermal source at the central massive black hole (Sgr A*), spiral-shaped streams of gas falling onto Sgr A* (Sgr A West), and the ring-shaped supernova remnant shown here (Sgr A East).

A schematic view of the radio image. One arcmin corresponds to about 2.3 pc (7 light years) at the distance of the Galactic Center (about 30,000 light years). The dotted line corresponds to the Galactic Plane.
