"When I looked in the Hubble archive and realised no one had observed these nebulae with Hubble's Wide Field Camera 3 across its full wavelength range, I was floored," said astronomer Joel Kastner of Rochester Institute of Technology in New York.
纽约罗切斯特理工学院的天文学家Joel Kastner说:“我查看了哈勃的档案,发现此前没有人利用哈勃第三代广域照相机的全波长范围观察过这些星云,我很诧异。”
"These new multi-wavelength Hubble observations provide the most comprehensive view to date of both of these spectacular nebulae. As I was downloading the resulting images, I felt like a kid in a candy store."
“通过这些新的多波长哈勃观测看到的是这些壮观星云目前最综合的视图效果。我下载传回的图像时,感觉自己就像一个进了糖果店的孩子。”
Both nebulae are probably descended from progenitor stars around three to five times the mass of the Sun; these progenitors collapsed into white dwarfs when they died. (Stars more massive than eight solar masses become neutron stars; and stars greater than 30 solar masses become black holes.) And both have high ionisation and excitation, indicating the stars inside them are very hot.
这两个星云的前身可能都是恒星,质量是太阳的3-5倍。这些恒星死亡时坍缩成白矮星。(质量大于8个太阳质量的恒星会成为中子星;大于30个太阳质量的恒星成为黑洞。)这两个星云都有高电离度和高激发度,说明其内部的恒星非常热。
