Stellar wind disrupting star formation in Orion Nebula: NASA

The from a newborn in the is preventing more new stars from forming nearby, according to a new research.

This is surprising because until now, scientists thought that other processes, such as exploding stars called supernovae, were largely responsible for regulating the formation of stars.

for Infrared (SOFIA)'s observations suggest that infant stars generate stellar winds that can blow away the seed material required to form new stars, a process called feedback.

is a 747SP jetliner modified to carry a 106-inch diameter telescope.

"The wind is responsible for blowing an enormous bubble around the central stars," said Cornelia Pabst, doctoral student at the in the Netherlands.

"It disrupts the natal cloud and prevents the birth of new stars."

The is among the best observed and most photographed objects in the night sky. It is the closest stellar nursery to Earth, and helps scientists explore how stars form.

At the heart of the lies a small grouping of young, massive and luminous stars.

Observations from SOFIA's instrument the German Receiver for at Terahertz Frequencies (GREAT) revealed that the strong from the brightest of these baby stars, designated as Theta1 Orionis C, has swept up a large shell of material from the cloud where this formed, like a snow plow clearing a street by pushing snow to the road's edges.

At the centre of the Nebula, the from Theta1 Orionis C forms a bubble and disrupts birth in its neighbourhood. At the same time, it pushes to the edges of the bubble, creating new regions of dense material where future stars might form.

These feedback effects regulate the physical conditions of the nebula, influence the star formation activity and ultimately drive the evolution of the interstellar medium -- the space between stars filled with gas and dust.

"Understanding how star formation interacts with the interstellar medium is key to understanding the origins of the stars we see today, and those that may form in the future," the researchers said.
