The Nature and Weirdness of the Orion Nebula

Описание: Located approximately 1,344 light-years away, the Orion Nebula (M42) is the premier laboratory for observing the violent process of stellar birth. However, recent data from the JWST and GAIA reveals an environment far more "bizarre" than previously imagined.

This presentation dives deep into the nebula's inner realm, moving past its photogenic facade to explore high-energy anomalies: the intense radiation of the Trapezium cluster, the expansive Orion-Eridanus Super bubble, and the mysterious Large Velocity Dispersion that suggests a hidden 150-solar-mass black hole. We will further examine the "weirdness" of the Kleinmann-Low Nebula and the discovery of JuMBOs—Jupiter-Mass Binary Objects—that defy standard star-formation models. Attendees will discover how this iconic celestial landmark continues to challenge our fundamental understanding of gravity, chemistry, and the evolution of planetary systems.

Speaker: Justin McCollum is a multi-disciplinary physicist currently serving as the Orbital Mechanics Data Specialist and Researcher for American Data Science (2024 – Present). With over two decades of experience in the field, he also holds concurrent roles as an Adjunct Instructor of Physics and Astronomy at both the University of Houston-Clear Lake (2015 – Present) and Houston Community College (2011 – Present).

He earned his Master of Science in Physics from Portland State University (2005) and recently graduated with a Post-Graduate Certification in Artificial Intelligence and Machine Learning from the University of Texas at Austin (2023). His research integrates high-energy astrophysics with modern data science, focusing on complex environments like the Orion Nebula. A dedicated science communicator, Justin is a long-standing member and frequent presenter for the Fort Bend and Houston Astronomical Societies
