Seyfert 2 Galaxy Markarian 463
Obtained with the Hubble Space Telescope Faint Object
A cone of illuminated material is seen in this false color
ultraviolet image of the Seyfert 2 galaxy Markarian 463 obtained
with the Hubble Space Telescope Faint Object Camera. The spot
nearest the center is the Seyfert 2 nucleus, the only obvious
structure in ground-based images. This spot is a decoy diverting
attention from the true quasar-like nucleus at the cone's apex
[marked by a plus sign].
The true nucleus is blocked from direct view by an opaque ring of
dusty material. Its light escapes only along the ring's axis,
forming the bright wedge seen here. Light scattered off dust or
electrons is polarized perpendicular to its direction of travel.
Polarizing filters in the Faint Object Camera were used to
observe the polarization direction [the short white lines] and
deduce the location of the light source, seen here to be at the
apex of the cone.
