先简单说一下,详细翻译等会儿吧。
好吧,现在来把它完成。——2009.3.24 by gohomeman1
Perseus' Stellar Neighbors
Baby stars are forming near the eastern rim of the cosmic cloudPerseus, in this infrared image from NASA's Spitzer Space Telescope.
英仙座星云邻居
在这张Spitzer卫星的红外光图像中,英仙座星云的东部区域(右边)附近正在形成新恒星。
The baby stars are approximately three million years old and are shownas reddish-pink dots to the right of the image. The pinkish colorindicates that these infant stars are still shrouded by the cosmic dustand gas that collapsed to form them. These stars are part of the IC348star cluster, which consists of over 300 known member stars.
图像的右边,那些粉红色的恒星婴儿大约才300万岁。粉红的颜色表明这些恒星还被原始星云收缩的星云盘外层包围着。这些恒星是IC348星团的一部分,IC348包含300多个已知恒星。
The Perseus Nebula can be seen as the large green cloud at the center of the image. Wisps of green are organic molecules called Polycyclic Aromatic Hydrocarbons (PAHs) that have been illuminated by the nearby star formation. Meanwhile, wisps of orange-red are dust particles warmed by the newly forming stars.
英仙座星云的中心呈现大片绿色。丝状绿色结构是星云中的多环芳香烃有机物被邻近的恒星照亮的结果。同时呈现橘红色的是被新生恒星照亮变暖的尘埃粒子。
PS:说明有机物并非地球附近特有,宇宙中多的是。多环芳香烃主要是萘、苯等以C、N为骨架,包含O、H等元素的有机物,有的还包含S、P等元素。
The Perseus Nebula is located about 1,043 light-years away in the Perseus constellation.
英仙座星云位于离我们1043光年的英仙座内。
The image is a three channel false color composite, where emission at4.5 microns is blue, emission at 8.0 microns is green, and 24-micronemission is red.
图像同样是伪彩合成的(另眼系列几乎都是伪彩的):蓝:4.5微米;绿:8.0微米;红:24微米。 |
