3D map reveals our solar system's local bubble has an 'escape tunnel'www.space.com/milky-way-hot-cold-local-bubble-supernovas

The investigation has revealed a large-scale temperature gradient within this bubble, called the Local Hot Bubble (LHB), meaning it contains both hot and cold spots. The team suspects that this temperature gradient may have been caused by exploding massive stars detonating in supernovas, causing the bubble to be reheated. This reheating would cause the pocket of low-density gas to expand.

This revealed that the LHB is stretched toward the poles of the galactic hemisphere. Hot gas expands in the direction that offers the least resistance, which, in this case, is away from the galactic disk. Thus, this wasn't a huge surprise to the researchers as it is also finding that had been revealed by eROSITA's predecessor, ROSAT, around 3 decades ago.
But, the new 3D map did reveal something hitherto unknown.
"What we didn't know was the existence of an interstellar tunnel towards Centaurus, which carves a gap in the cooler interstellar medium," team member and MPE physicist Michael Freyberg said in the statement. "This region stands out in stark relief thanks to the much-improved sensitivity of eROSITA and a vastly different surveying strategy compared to ROSAT."
It seems to me that I read either this article or another one like it, not too long ago. Yes, we are getting more subtle instruments, This plotting sounds familiar! Yggdrasil, anyone?

I can’t recall where I read something like this article,sorry. Yggdrasil can be found at https://en.wikipedia.org/wiki/Yggdrasil
Yggdrasil was basically the tree of the cosmos with 9 planets connected to it with different peoples on each. If you saw the “Thor” movies by Marvel they featured it in some of them. They also featured it in the first “Captain America” film, right at heh beginning.
