In star-forming clouds, what carving mechanism is responsible for creating features like the Pillars of Creation in the Eagle Nebula?
Answer
Radiation pressure and stellar winds carving out areas where dust density is lower.
Features such as the Pillars of Creation within the Eagle Nebula are sculpted by the powerful output of the massive, young stars forming nearby. The shaping process involves two main forces acting on the parent cloud: intense radiation pressure pushing gas outwards, and powerful stellar winds acting like blasters. These forces erode the surrounding diffuse gas more quickly, leaving behind towering columns composed of denser gas and dust that are more resistant to evaporation, thus creating the iconic, tower-like structures.
