Abstract: A planetary nebulae consists of a hot, luminous central star and an expanding glowing shell of gas and dust. The central star of most of the planetary nebulae (PNe) is a very hot object which is bright in ultraviolet (UV) and hence, UV observations explore the properties of these objects. We present the UV images of 108 PNe using observations made by Galaxy Evolution Explorer (GALEX). We have determined the angular diameter of PNe in NUV and also in FUV for whichever source detection exists considering a 3σ emission level above the background. We determine the morphology and many other physical parameters related to UV observations of PNe.
