Bubble Nebula, Amanda Kraker

Bubble Nebula

In the center of the Bubble Nebula there are clusters of extremely hot stars (Wolf-Rayet type). The reason the star clusters are categorized that way is due to the fact that they have stellar winds that come off of their surfaces. When these winds crash into the interstellar medium, it results in the interstellar medium glowing in the shape of a visible bubble nebula.

In this photograph, one can distinctly see the bubble nebula. This is from, as aforementioned, stellar winds crashing into the interstellar medium, creating an extremely hot, glowing interstellar medium. There is also some visible gas and interstellar dust located near the Bubble Nebula itself, and this helps to showcase the luminous bubble. These regions of interstellar medium are very dense due to the amount of gas and dust within it. The linear size of the nebula is roughly 3000 lightyears across the length, and 3000 lightyears across the width. You can also see the giant proto star in the middle of the nebula which formed after the collapsing and spinning of dense interstellar material. This Bubble Nebula gracefully showcases the beauty and power of our Lord and the complexity and majesty with which He creates the universe.
