X-ray image of Centaurus A
This Chandra image of Centaurus A, taken with its High
Resolution Camera, clearly show two arc-like structures
of multimillion-degree gas surrounding the jet blasting
away from the supermassive black hole in the
nucleus.

Optical image of Centaurus A
Covering the same area of sky as the Chandra image,
this optical view reveals that Centaurus A is a giant
elliptical galaxy with a band of dust and other cool
material across the center.

X-ray/Optical Composite
An overlay of the X-ray and optical data demonstrates
how the X-ray arcs trace a ring around the galaxy as
seen in visible light.

This VLA 21-cm radio image shows synchrotron radiation from high-energy
electrons
The radio emission from the region of the
electromagnetic spectrum reveals radio synchrotron
radiation from high-energy electrons.

Cen A HRC-I X-ray Image
Cen A HRC-I X-ray image (dark blue) superimposed with the VLA radio
continuum map of the inner jet lobes (red contours), and the VLA radio
21-cm line HI gas emission (green contours). The white dashed line is a
schematical outline of an optical arc-like shell.

Optical image of Centaurus A
Visible in the upper right corner of this optical
image of the Centaurus A Galaxy is an arc of blue stars
left behind when Centaurus A pulled in a smaller galaxy
and tore it apart. Astronomers say the scar from this
cosmic collision is fairly new and thousands of light
years long.
