white nebula的意思|示意

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。

In only a few thousand years the nebula will dissipate into space. The central star will then gradually cool down, eventually becoming a White Dwarf, the final stage of evolution for nearly all stars.

在仅仅的几千年里，星云将消散在太空中，中心的恒星将完全冷却下来，最后变成白矮星，这是几乎所有恒星演化的最后阶段。
