Astronomers have discovered an “interstellar tunnel” in our solar neighborhood, part of the Local Hot Bubble (LHB), an enormous structure of hot gas surrounding our solar system.

A new study, using data from the eROSITA x-ray telescope, revealed the tunnel, which could connect to a nearby larger bubble.

The LHB, first proposed over 50 years ago, was thought to be created by supernovas that blew away interstellar material, forming a 1,000-light-year cavity.

This discovery supports the idea of an interstellar medium network across the Milky Way, Futurism has reported.

The study also identified a temperature gradient in the bubble, suggesting recent supernova activity.
