简单的物理学定律揭示出，星际介质中的气尘复合体可以进化，先是演化为原恒星，接下去再演化为恒星。
Simple laws of physics suggest, that gas-dust complexes in the interstellar medium may evolve, first into protostars and subsequently into stars.
但受其周围厚厚的云团(象鼻星云本身)和原恒星周围尘埃的影响，这些原恒星以前无法被可见光波长的探测器所发现。
These were previously undetected at visible wavelengths due to obscuration by the thick cloud (' globule body ') and by dust surrounding the newly forming stars.
“太阳总有一天会变成白矮星，这也是为什么我们有兴趣去了解更多以及如同原恒星那样在所有行星身上发生的一切。”在他笔记中这样写到。
"The sun will one day become a White Dwarf star, which is why we're interested in knowing more about them and what happens to any planets the original star might have had," Provencal notes.
NASA的斯比策空间望远镜捕获到一个处于黑色的水滴状星云中的恒星摇篮，在这里诞生了新的原恒星，或者叫做恒星的胚胎；这里还发现许多从未见过的年轻恒星。
NASA's Spitzer Space Telescope captured a glowing stellar nursery within a dark globule that reveals the birth of new protostars, or embryonic stars, and young stars never before seen.
当这个盘状物开始合并成为一组原行星时，它们的引力拉动着盘状物周围气体所凝聚的硬块，一起环绕着恒星作轨道运行。
When the disk begins to coalesce into protoplanets, the gravity of those protoplanets pulls clumps of gas around the disk with them as they orbit the star.
他们的形体能达到多大取决于他们离恒星的距离和原行星星云的组成。
How big they get depends on their distance from the star and the density and composition of the protoplanetary nebula.
斯皮策的数据则显示出这些年轻恒星是否有所谓的“原行星”盘环绕着他们自己。
