Abstract: We present the first ultraviolet (UV) photometric observations of planetary nebulae (PNe) using observations made by Galaxy Evolution Explorer (GALEX). We found about 112 PNe observed by GALEX. We have determined the angular diameter of PNe in NUV and also in FUV for whichever source detection exists considering a 3¾ emission level above the background. Of the PNe, 20% are elliptical, 7% are bipolar and rest are circular in UV. The emission lines contributing to GALEX FUV flux are strong OV, C IV, and He II while the emission line contributing to the NUV flux are C III] and He II.
