Just in time for the fall foliage season, this image from the NASA/ESA Hubble Space Telescope features a glistening scene in red. 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).
The frEGG in this image is the small tadpole-shaped dark region in the upper center-left. This buoyant-looking bubble is lumbered with two names—[KAG2008] globule 13 and J025838.6+604259.
FrEGGs were classified even more recently and are distinguished from EGGs because they are detached and have a distinct 'head-tail' shape. FrEGGs and EGGs are of particular interest because their density makes it more difficult for intense UV radiation, found in regions rich in, to penetrate them. Their relative opacity means that the gas within them is protected from ionization and photoevaporation.
