It reveals a small region of the nebula Westerhout 5, which lies about 7,000 light-years from Earth.

Suffused with bright red light, this luminous image hosts a variety of interesting features, including a free-floating Evaporating Gaseous Globule (frEGG).

This buoyant-looking bubble is lumbered with two names - [KAG2008] globule 13 and J025838.6+604259. FrEGGs are a particular class of Evaporating Gaseous Globules (EGGs).

Both frEGGs and EGGs are denser regions of gas that photoevaporate less easily than the less dense gas surrounding them.

Photoevaporation occurs when gas is ionized and dispersed away by an intense source of radiation – typically young, hot stars releasing vast amounts of ultraviolet (UV) light.

FrEGGs and EGGs, with their dense, opaque gas, resist UV radiation in young star regions, shielding them from ionization and photoevaporation.
