Edge of Orion Nebula reveals steep transition from hot ionized gas to cold molecular cloud
Orion Nebula studied in detail using James Webb Space Telescope
PAH molecules play crucial role in Orion Nebula's vibrant colors and complex structure
Star formation occurs in overdense patches of gas and dust
The Orion Nebula, a well-known celestial object located approximately 1,500 light years from Earth in the constellation of Orion, has recently been studied in unprecedented detail by researchers using the James Webb Space Telescope (JWST). This star-forming region is significant as it is the closest large stellar nursery to our solar system. The JWST images reveal new insights into this fascinating area, showcasing intricate details that were previously unseen.
The Orion Nebula, also known as Messier 42 (M42), has been a subject of interest for astronomers due to its proximity and brightness. The JWST's advanced capabilities have allowed researchers to examine the nebula's composition and dynamics in greater detail.
Star formation occurs when overdense patches in a cloud of gas and dust collapse under their own gravity, forming protostars wrapped in natal cocoons. The Orion Nebula is an excellent laboratory for studying this process. The JWST images reveal that the edge of the Orion Bar, which marks the transition from hot ionized gas near the Trapezium stars to cold molecular cloud on the other side, is very steep and resembles a huge wall.
PAH molecules are among the largest reservoirs of carbon-based materials in the cosmos and are relevant to our understanding of life on planets that form around young stars. The JWST images reveal that these molecules play a crucial role in the Orion Nebula, contributing to its vibrant colors and complex structure.
The Orion Nebula serves as an important reminder of the ongoing process of star formation and the vast diversity of celestial objects in our universe. Further research using advanced telescopes like JWST will undoubtedly yield new discoveries and deepen our understanding of this fascinating phenomenon.

Researchers with the PDRs4All program, consisting of members from several universities including Western University, released new research on the Orion nebula this week.
The new images captured by the James Webb Space Telescope have such an incredible detail that they will be scrutinized for many years to come.
A specific part of the nebula known as the ‘Orion Bar’ was the focus of the new images released this week.
Researchers have charted the Orion Nebula like never before using the James Webb space telescope (Webb).
The JWST image captures the Orion Bar, which marks the transition from hot ionized gas near the Trapezium stars to cold molecular cloud on the other side.
The Orion Bar is made up of leftover material from the cloud that formed these stars.
Intense radiation from young hot stars transforms the gas and dust in and beyond the Orion Bar.
Western University astrophysicists were among the first to use James Webb space telescope for scientific research, focusing on star formation.
Star formation is a process that involves the gravitational collapse of a gas and dust cloud, resulting in massive and modest stars surrounded by planet-forming disks.
The Orion Nebula image captured by Webb is an RGB composite with blue showing ionized gas emission, red showcasing large carbonaceous molecules emission, and green tracing warm dust and molecular gas.
Jan Cami expresses the importance of understanding how planet-forming disks are sculpted or destroyed and seeded with life-important chemicals.
