fb 的朋友指出 : 其實只係攝影同圖像處理上令冥王星變左非球體,NASA個press release有說明架 . "Pluto’s non-spherical appearance in these images is not real; it results from a combination of the image-processing technique and Pluto’s large variations in surface brightness. " "Pluto is known to be almost perfectly spherical from previous data"
