| Abstract: | The massive and active galaxies in the core of the Virgo Cluster were shown in 1968 to be aligned on either side of M 87,
along the direction of the jet and counter-jet. Recent observations confirm the significance of this alignment by showing
that the brightest X-ray sources, including additional large galaxies, define the same line.
Detailed X-ray maps of M 86 show that this galaxy, which is part of the alignment, is probably blown by a wind from M 87 due
to its close alignment with the jet. But the large radio E galaxy, M 84, which is 1.4 degrees away from M 87, andexactly along the line of the jet, is shown by the compression of its X-ray isophotes to be actually moving out along the line of
the jet. This evidence furnishes rather spectacular support for the earlier conclusion that M 84 had originated as a proto-galaxy
within M 87 and had been ejected out along the line of the jet.
