3C219 = B0917+458

• FR II (double-lobed) radio galaxy at z=0.1745 (544/h Mpc, H = 100h km/s/Mpc)
• Filamentary outer lobes extending several hundred kpc
• Bright, extended hot spots in both lobes
• Abbreviated (restarting?) jet and counterjet
• (Left) VLA 1.4+1.6 GHz combined image at 1.4 arcsec resolution
• (Right) VLA 8 GHz image of jets at 0.1 arcsec resolution
• Ultra-compact, aligned bright knots at both jet tips
• Other images available:
  • alternate view of large scale structure
  • optical/radio montage (17k JPEG) relating radio source to host galaxy
