Within this nebula, the hot core of the star remains-crushed to high density by gravity-as a White Dwarf with temperatures over 180,000 degrees Fahrenheit (100,000 degrees Celsius).
在星云内部，恒星的热核仍然存留着——其由重力挤压成了高密度物体——即温度超过180,000华氏度(100,000摄氏度)的白矮星。
This means the core is no longer producing a steady stream of photons, which in a living star creates outward pressure, keeping the star from being crushed by its own gravity.
这意味着核心是不再生产的光子，这创造了明星生活源源不断地向外压力，不让其自身的重力撞死的明星。
