50-Year-Old Mystery Solved As Secret White Dwarf Found To Be Source Of X-Rays In Gamma CassiopeiaAt the centre of a black canvas a large ball shines in shades of white and blue. The ball is surrounded by a light-blue and white disc with a fuzzy texture, like that of a dense gas. The disc connects by a bluish ribbon to a smaller disc surrounding a smaller glowing white ball, located in the lower left of the image. Two light-blue, shiny, arches of gas shoot out from opposite sides of the smaller disc and meet at the top-pole of the smaller ball
