Orion’s Veil might be breaking, according to the latest observations

“The bubble – with a diameter of approximately seven light-years – should be an almost sphere-like structure, but we found a protrusion in its northwestern part,” explained Ümit Kavak, a postdoctoral researcher at SOFIA based out of NASA’s Ames Research Center in California’s Silicon Valley, who is the lead author on a recent paper in Astronomy & Astrophysics describing the studies.

According to the SOFIA observations, this protrusion emits ionized carbon, which Kavak used to determine its size, structure, and the rate at which it is growing in order to gain insight into its origins and future.

The protrusion extends far beyond Orion’s Veil, resembling a “U” lying on its side. Considering the chimney-like top of the protrusion, it is likely that the shell has already penetrated there.

“When you breach the Veil shell, you effectively start stirring a cosmic soup of gas and dust by adding turbulence,” Kavak said.

“This isn’t the most appetizing soup, but it’s one of the ways to form new stars or limit future star formation,” added Alexander Tielens, a researcher at Leiden University and a co-author of the paper.

Turbulence can, in turn, affect the density, temperature, and chemistry of the surrounding region, which, in turn, affects star formation.

They also discovered a second protrusion that will be investigated further in a future paper. They have a profound effect on the overall morphology of the Orion Nebula as a whole.

Developed by NASA and the German Space Agency at DLR, SOFIA is a joint project of both agencies. DLR provides maintenance services for the aircraft, telescope maintenance, and other mission support. With the Universities Space Research Association, based in Columbia, Maryland, and the German SOFIA Institute at the University of Stuttgart, NASA’s Ames Research Center in California’s Silicon Valley manages the SOFIA program, science, and mission operations.
