Very cool, our solar system has an atmosphere, which seems obvious but isn’t discussed or taught at least when I was in high school.

Basically, the Oort cloud. Except for the high temps, which are the surprise.

Well, not a surprise. They predicted it before measuring it.

From my understanding the wall is not the Oort cloud but instead the solar winds bouncing off the exterior winds more like how the Pacific and Atlantic oceans don’t mix.

One of my favorite quotes from one of my Astro professors is "Everything has an atmosphere, it is a matter of how tenuous".

I think the article shows how relevant this still is today.
