dc.descriptionWFPC2 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 10E11 solar mass black hole, in contrast to earlier suggestions.
