Description
We present optical and millimeter (continuum and molecular) observations
of a cometary globule in the Trifid nebula showing clear signs of star
formation activity. The globule is associated with a long jet finishing
in a large bow shock. The HH jet can be seen in all the popular pictures
of the Trifid. It has remained unrevealed although it has been in front
of our eyes since the first high sensitivity photographic pictures of
the Trifid. The jet emanates from the head of a cometary globule
submitted to the strong UV field of the ionizing star of the Trifid. The
continuum emission at 230 GHz follows the globule's head contour and
consists of extended and weak emission plus a strong point source from
where the jet seems to arise. High resolution spectroscopy in the SII
line at 6730 A indicates that the jet is practically in the plane of the
sky. The dust emission arises from a clump of ~= 5 M_odot. The
molecular observations cover a larger surface and indicate a total mass
for the globule of 30-50 M_odot.
