The Visible Nulling Coronagraph (VNC) combines an interferometer with a coronagraph to image and characterize Jovian-size planets. In this photo, Goddard scientists Rick Lyon (foreground) and Udayan Mallik (left), who are joined by Pete Petrone (right), an employee of Sigma Space Corporation in Lanham, Md., are monitoring the progress of wavefront control using the VNC, which is operating inside a vacuum tank.
