German astronomers have discovered an interstellar tunnel connecting the Solar System to the constellation Centauri. The tunnel is part of a larger network formed by stellar winds and supernova explosions.
The interstellar path probably connects to another neighboring gas bubble, which is formed by the explosion of young stars, emits X-rays, and extends about a thousand light-years around the solar system. The discovery is important, in particular, in terms of studying the local bubble in which the solar system is located, reports UNN with reference to BBC.

Scientists from Germany, observing the Local Hot Bubble or LHB – the superbubble and region of space in which our solar system is located – through a high-powered telescope , have suddenly discovered something completely unexpected: an interstellar tunnel.
“This region of space is characterized by a very low-density hot gas with a temperature of one million degrees Kelvin and a density of less than 0.01 particles per cm3,” explains Michael Yeng, a doctoral student at the Max Planck Institute for Extraterrestrial Physics (MPE).
What we didn't know was the existence of an interstellar tunnel to Centauri, which tears a hole in the colder interstellar medium (ISM)
– said Michael Freiberg, a scientist at the Max Planck Institute for Extraterrestrial Physics and another author of the study.
An interstellar tunnel is a connection between two supernovae remnants or superbubbles filled with hot gas.

According to the researchers, the Centauri Tunnel is part of a larger network of tunnels formed by stellar winds, supernova explosions, and jets released by protostars.
“The current view is that it is related to recent supernova explosions that have expanded the LHB,” Yang said.
