FIg9_7 Cosmic eggs

Fig. 9.7 . A cloud of cool interstellar dust and molecular hydrogen gas may have embryonic, unseen stars embedded inside it. Ultraviolet light from nearby hot stars uncovers dark globules of gas at the top of the cloud, each about the size of our solar system. They have been called “eggs,” an acronym of evaporating gaseous globules. This cloud is located in the Eagle Nebula, also designated as M 16.
