Stars in the process of formation, called young stellar objects or YSOs, are embedded in the compact pinkish nebulae seen here, but are otherwise hidden from the prying eyes of optical telescopes.

在形成过程中的恒星，被称为年轻恒星或者yso，都嵌在了你所看到的紧凑的粉色星云之中，不过如果通过光学望远镜来观察的话是看不到的。

Supernova remnants play an important role in stellar evolution by enriching space with heavy elements, and triggering new star formation by compressing interstellar gas.

超新星残骸以重元素填充宇宙空间，压缩星际气体促进新恒星的形成，因而在星体演化过程中扮演重要角色。

Similarly, the size and longevity of stellar disks, and thus the efficiency of planet formation, depend crucially on the role played by dynamical interactions in the stellar womb.

相似地，恒星气盘的大小与寿命，和与此相关的行星形成效率， 主要取决于恒星发源地内动态交互作用所扮演的角色。

The presence of multiple orbiting companions is incompatible with the mechanism of stellar formation so they must be planets after all.

ECONOMIST: Planet hunting

Besides requiring astronomers to dream up a new mnemonic for their stellar classification, the existence of a grey area between stars and planets reveals the extent to which the processes of planetary and stellar formation are still a mystery.

ECONOMIST: Twinkle, twinkle, giant planet

Astronomers have long theorized that there are many planets that have drifted away from their home stars, whether it's a too-loose gravitational pull during the planet's formation or a stellar tug-of-war.
