Hubble shows a small part of the nebula Westerhout 5 as bright red.


The NASA/ESA Hubble Space Telescope captures a captivating scene awash in red hues.This image unveils a segment of the Westerhout 5 nebula, situated approximately 7,000 light-years away from Earth. Illuminated by vivid red light, the picture showcases various intriguing elements, including a free-floating Evaporating Gaseous Globule (frEGG), visible as a small tadpole-shaped dark region in the upper center-left, bearing the dual designations of [KAG2008] globule 13 and J025838.6+604259.

FrEGGs, a distinct subclass of Evaporating Gaseous Globules (EGGs), represent denser gas regions resistant to photoevaporation compared to their less dense surroundings. Photoevaporation, induced by intense ultraviolet (UV) light from young, hot stars, ionizes and disperses gas. EGGs were identified relatively recently, notably at the tips of the iconic Pillars of Creation captured by Hubble in 1995. FrEGGs, classified even more recently, stand out due to their detached, ‘head-tail’ shape. Both frEGGs and EGGs are of particular interest because their density shields the gas within from ionization and photoevaporation, making them potential sites for protostar formation.

The dark frEGG in the sea of red light draws attention against the backdrop of H-alpha emission, a type of light emission resulting from the release of distinctive red light when a highly energetic electron within a hydrogen atom loses a specific amount of energy. This arresting image not only captivates with its autumnal aesthetic but also offers valuable insights into the intricate processes of gas and star formation within cosmic landscapes.

My name is Surendra Uikey, I am a science blogger, I have been blogging for the past three years, because I love to write, especially on astronomy, and I believe, if you want to learn something, then start learning others, By this it will be, that you learn things in a better way. In 2019, I started, the aim of making was to connect astronomy in simple words to common people.
