WFPC2 images and STIS spectroscopic observations are presented of the
double nucleus in the merger system NGC 6240. We find that: (a) the
kinematics of the ionized gas is similar to that of the molecular gas,
despite a different morphology; (b) the gaseous and stellar kinematics
are quite different, suggesting an early merger stage; (c) neither the
gaseous nor the stellar kinematics show an obvious sign of the
supermassive black hole believed to be responsible for the X-ray
emission of NGC 6240; and (d) the steep off-nuclear velocity gradient
is not due to a 10^11 solar mass black hole, in contrast to earlier
