353-comet-nucleus-dixon – A dark, irregular cometary nucleus vents volatile gases and dust as it heats up in interplanetary space. Linear jets of outgassing material erupt directly from the sunlit surface, feeding into a vast, glowing blue coma structured by fine, radial filaments. A distinct, elongated shadow is cast by the nucleus directly behind it, cutting through the illuminated haze of the surrounding dust and gas envelope. digtial, 2003
