Type of Object:  Virgo A is a giant elliptical galaxy is the center of the cluster of galaxies in the constellation Virgo.  Vir A is perhaps best noted for the jet moving relativistically being ejected from the galaxy.  The power source of the jet is thought to be a supermassive (several million times the mass of the sun) black hole at the center of the galaxy.  With a visible magnitude of about 8.5, the galaxy can be photographed using even a small telescope.

0.5 degree x 0.5 degree area of the sky centered on the nebula.  The images are taken from the SKYVIEW Virtual Observatory maintained under NASA ADP Grant NAS5-32068 with P.I. Thomas A. McGlynn under the auspices of the High Energy Astrophysics Science  Archive Research Center (HEASARC) at the GSFC Laboratory for High Energy Astrophysics. SKYVIEW contains catalogs and surveys from x-ray to radio observations. The site is located at http://skyview.gsfc.nasa.gov/

Visible image from the digitized Palomar Sky Survey E plates.  The jet from the galaxy is seen protruding from the lower right of the galaxy as a short bright line.

Far-Infrared Image at 100 microns taken by the Infrared Astronomical Satellite (IRAS) Survey. Shows bright gas emission near Vir A.

Image taken at the radio emission of neutral hydrogen at 1420 MHz by the NRAO VLA Sky Survey.  Shows the gas surrounding Vir A. Note the asymmetry of the gas emission.

Image taken at the radio emission frequency of 4850 MHz. Image shows the gas component.  Image is from a Green Bank survey from 0° to +75° declination).
