Photoevaporation is the process by which gas is ionized and dispersed by intense sources of radiation, typically young, fiery stars emitting copious amounts of ultraviolet (UV) light.
EGGs were identified, most notably at the tips of the legendary Pillars of Creation.FrEGGs, a more recent discovery, can be distinguished by their detached nature and distinctive “head-tail” configuration.
Their opacity shields the gas within, preserving it from ionization and photoevaporation. Researchers believe this unique quality is instrumental in the formation of protostars.
The red hue emanates from a phenomenon known as H-alpha emission, a striking occurrence when an energetic electron within a hydrogen atom sheds a specific amount of energy, casting a distinctive red glow as it loses its vitality.
