It appears that rogue planets – free floating worlds that aren’t gravitationally bound to a parent star – might be more common than we thought. New data from the James Webb Space Telescope have revealed 540 (yes, that’s right) planetary-mass objects in the Orion Nebula and Trapezium Cluster.
If confirmed, this would be by far the largest sample of rogue planets ever discovered.
The Orion Nebula is one of the most observed and photographed objects in the night sky. At a distance of 1350 light years away, it’s the closest active star-forming region to Earth.
This diffuse nebula is also known as M42, and has been studied intensely by astronomers for many years. From it, astronomers have learned a lot about star formation, planetary system formation, and other bedrock topics in astronomy and astrophysics. Now a new discovery has been made which goes against the grain of established theory: stellar winds from newly-formed massive stars may prevent other stars from forming in their vicinity. They also play a much larger role in star formation, and in galaxy evolution, than previously thought.
