Our solar system resides within a bubble of superheated gas known as undefined (LHB). Scientists have long pondered its origins.

To better study this region, undefined for Extraterrestrial Physics (MPE) researchers used data from the eROSITA All-Sky Survey.

And they spotted a fascinating feature within undefined an interstellar tunnel towards the constellation Centaurus. This tunnel may connect our local bubble to neighboring superbubbles, forming a vast network of hot gas.

"The highlight of this work features the discovery of a new interstellar tunnel towards the constellation Centaurus, potentially joining our LHB with a neighboring superbubble," the authors noted in the press release.

Our solar system is situated inside a vast, 1,000-light-year-wide cavity, Local Hot Bubble. This idea was first introduced about 50 years ago.

This bubble is a rarified region of interstellar space, much less dense than the surrounding medium. Moreover, the hot bubble is filled with a tenuous, million-degree gas emitting soft X-rays.

Astronomers have analyzed data from the eROSITA X-ray telescope to map undefined's structure and properties in unprecedented detail.

As per the press release , the eROSITA data uncovered a large-scale temperature difference within the bubble. This suggests that past supernova explosions may have heated and expanded the bubble, creating a complex and dynamic environment.
