Interesting and thanks for posting Marc.
It got me thinking.
A satellite orbiting where the plumes have been observed and get samples of one which may indicate life.

Interesting, thank you Marc.

In January, SOFIA-collected data was published in an article explaining that solar wind from the toddler star Theta Ori C pushes its nursery cloud outwards and by that stops further star formation at its own nursery.

But causing new densities to form at the outskirts of its "snow plow wave".

In the new image, I would have expected to see magnetic lines corresponding to that "snow plow" wave. Assuming, denser particle concentration at the outskirts also causes denser magnetic lines.
Not so at all. Magnetic lines are spread completely even '"in" the area of the Trapezium.

Hm.

Or.. am I looking to close to the Trapezium and should look further out?

Close to Theta 2 Ori, the first in the line of 3 stars, where something is accumulating bigly. Perhaps, Theta1 Ori C's snow plow wave already reaches so far out and only here it is crashing into the lesser snow plow wave of Theta 2 Ori. Causing accumulation of stuff and densing their magnetic lines.

In the January article they state "create a 'bubble' roughly four parsecs in diameter ".
Uhm, how big is 4 parsecs :confused2:

Okay, I think I was able to google and comprehend it a little. Parsecs is somewhat similar to arcsecs, plus the "par" from parallax.

SkySafari shows the distance from Theta 2 Ori to Theta 1 Ori as about ~ 1.8 arcminutes. So the "dam" of magnetic lines close to Theta 2 Ori isn't the fringe of the "bubble" created by Theta 1 Ori as described in the January article which is only 4 arcseconds big.

The "bubble" finds no representation in the new image of the magnetic lines.
