是什么创造了这个不寻常的太空雕塑？星星。这个不寻常的漩涡和贝壳系统被称为阿佩普，美国宇航局的詹姆斯韦伯太空望远镜在2024年用红外光观察到前所未有的细节。观测表明，这种不寻常的形状源于两颗巨大的沃尔夫-拉叶星，它们每隔190年绕对方运行一次，每次近距离通过都会产生新的尘埃和气体外壳。这些外壳上的洞被认为是由第三颗绕轨道运行的恒星造成的。这种恒星尘埃舞蹈可能会持续数十万年，可能只有当其中一颗大质量恒星耗尽内部核燃料并以超新星爆炸的形式爆炸时才会结束，并伴随着伽马射线的爆发。建立你自己的恒星系统：天文难题的一天

What created this unusual space sculpture? Stars. This unusual system of swirls and shells, known as Apep, was observed in unprecedented detail by NASA’s James Webb Space Telescope in infrared light in 2024. Observations indicate that the unusual shape originates from two massive Wolf-Rayet stars orbiting each other every 190 years with each close passes causing a new shell of dust and gas to be expelled. Holes in these shells are thought to be caused by a third orbiting star. This stellar dust dance will likely continue for hundreds of thousands of years, possibly ending only when one of the massive stars runs out of internal nuclear fuel and explodes in a supernova punctuated by a burst of gamma-rays.
