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).

Schematic
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.
