A Herbig-Haro object occurs at the interface of a new star's emissions with this, and the thorium detected in it supports the theory of Bok globules.
A Herbig-Haro object occurs at the interface of a new star's emissions with this, and the thorium detected in it supports the theory of Bok globules. This aggregation of matter contains three phases, which differ in their degree of ionization and temperature, and it is generally transparent to electromagnetic waves of length more than about 912 Angstroms, which is known as the Lyman limit. For 10 points, name the diffuse, weakly ionized, chiefly hydrogen astronomical plasma whose interface with the solar wind is known as heliopause, and which is named for its occupation of areas of the galaxy far from stars.
