EGGs and FrEGGs
This radiant nebula is not without its quirks, featuring a captivating Evaporating Gaseous Globule (frEGG). The small, tadpole-shaped dark region located in the upper center-left of the image is a captivating celestial oddity, bearing the dual monikers [KAG2008] globule 13 and J025838.6+604259.
There is evidence that many FrEGGs and EGGs serve as cradles for the birth of new stars. These dense pockets of gas possess an innate resistance to the surrounding ionizing radiation, crafting a protective “egg” within which new stars can take their first breaths.
A notable example of these enigmatic structures can be found in the iconic Pillars of Creation image, initially captured by Hubble in 1995.
Pictured as colorful protrusions, denser gas pockets known as FrEGGs stand out amidst their less dense counterparts. These regions, characterized by their resilience to photoevaporation, are classified as Evaporating Gaseous Globules (EGGs).
