eROSITA mission: A new interstellar tunnel found in our solar system’s hot bubble

A team of scientists from the Max Planck Institute for Extraterrestrial Physics (MPE) used data from the eROSITA All-Sky Survey to uncover a large-scale temperature gradient within the Local Hot Bubble (LHB), a region of hot gas surrounding the solar system. This temperature variation may be linked to past supernova explosions, which could have expanded and reheated the bubble over time. In their study, the team created a new 3D model of the hot gas in the solar neighborhood, with a key discovery being the identification of a new interstellar tunnel pointing toward the Centaurus constellation.
