VLA & VLBA Jet Image NGC 315

Here is a splendid example of the difference in observing capabilities of the VLBA and the VLA. This is the jet emitted from the core of NGC315, a giant radio galaxy near the constellation Andromeda. The larger image is from VLA (B configuration) data at 4885 MHz, showing the kiloparsec dimensions of a typical galactic jet. The inset is a contour plot from VLBA data at the same frequency, showing a much smaller field of view with parsec-scale resolution. Note the similar alignment of the two images, which tends to confirm their association.
