Nasa ' s three great observatories - - the hubble space telescope , the spitzer space telescope , and the chandra x - ray observatory - - joined forces to probe the expanding remains of a supernova Nasa的三架大天文台，也就是哈勃太空望远镜、斯必泽太空望远镜以及钱德拉x射线天文台联合起来，探测着膨胀的超新星遗迹。
Observations from each telescope highlight distinct features of the supernova remnant , a fast - moving shell of iron - rich material from the exploded star , surrounded by an expanding shock wave that is sweeping up interstellar gas and dust 各望远镜的观测突出的是超新星遗迹不同的部位，恒星爆发产生的高速富铁壳层，周围包裹着膨胀的激波，扫过星际气体和尘埃。
Unlike the rapidly rotating neutron stars in the crab nebula and vela supernova remnants that are surrounded by dynamic magnetized clouds of electrons called pulsar wind nebulas , this neutron star is quiet , faint , and so far shows no evidence for pulsed radiation 与蟹状星云和船帆座超新星遗迹中被磁化电子云（脉冲星风星云）环绕的高速自转中子星不同，这颗中子星安静而虚弱，目前为止，没有显示脉冲辐射的迹象。
