As in an electric power plant, a rotating magnetic field produces an
electric field, which accelerates protons and electrons near the neutron
star's surface to generate an intense beam of electromagnetic radiation
along the magnetic axis (the white cones)

ABSTRACT Near-Ultraviolet imaging with HST offers the best possible spatial resolution currently available for
optical/UV astronomical imaging. The giant elliptical galaxy M87 hosts one of the most spectacular, best studied
and nearest (d=16 Mpc) galactic-scale relativistic (synchrotron emitting plasma) jets. We have extracted from the
HST archive all 220 nm images of the jet of M87, taken with the STIS MAMA camera and co-added them to provide
the deepest image ever at this wavelength. The combination of highest spatial resolution and long integration time,
42,500 seconds, reveals a wealth of complex structure, knots, filaments and shocks. We compare this image with deep
imaging data in other wavebands.
