The ghost in Orion's shell: Hydrogen maps show repeated stellar feedback sculpted around Orion Nebula

From the article

An international team led by Juan Diego Soler at the University of Vienna used two of the world's most powerful radio telescopes to uncover previously hidden structures within the Orion Nebula. The project produced the sharpest maps ever made of neutral hydrogen in that region of massive star formation. The findings expose the complex relationship of star-forming regions with their environment and suggest that the Orion Nebula has been shaped by multiple episodes of stellar feedback rather than a single expanding bubble. The study has been published in the journal Astronomy & Astrophysics.
