It is the remnant of a supernova explosion in the year 1054 much more about that during my next lecture and what you see here is not stuff that is generated at this moment in time by the pulsar.
它是超行星在1054年，爆炸后的剩余物4，下节课我会，详细讲它，这里你看到的不是，脉冲星那时，聚集的物质。
Most scientists agree a Type 1a supernova occurs when a White Dwarf star — a collapsed remnant of an elderly star — exceeds its weight limit, becomes unstable and explodes.
