Answer to Question 1

Young stars give off ultraviolet radiation, heating the surrounding gas cloud and causing it to glow as an emission nebula. Solar wind from the young stars pushes on the nebula, which can sweep away the gas, but can also cause compression leading to more new star formation.

Answer to Question 2

The distribution of gamma-ray bursts is distributed uniformly on the sky, unlike the distribution of X-ray binaries, neutron stars, and other objects within the Galaxy. Further, the afterglow of some gamma-ray bursts have now been detected and detailed observations at other wavelengths show that they are located at the position (and redshift) of distant galaxies.
