I would say it's a younger part of the nebula, or perhaps an area that was slower to evolve. I don't know if there is any way of knowing which. In star forming regions, things start out in tight knots of material which often form linear structures. I've seen a bunch of these in WISE data. You can bet money that any dark, black dusty area around a star forming area in visible light is actually full of YSOs. As you know, when stars are born they blow their natal clouds away and you can see that happening in the bright areas where a bubble has formed. The young stellar objects of the tight knots simply haven't yet matured into stars capable of producing those driving winds yet. Just a bunch of very red objects in other words. None of your favorite blue ones yet.

Depends on how you define famous. I have exchanged various tiny interactions via email between a handful of astronomers, some of which you may know the names of. Emily Lakdawalla and Phil Plait interact with me sometimes on Twitter.
