Astronomers Discover "Interstellar Tunnel" In Our Solar Neighborhood
Astronomers say they've found an "interstellar tunnel" near our solar system that potentially leads to the vicinity of other star systems. As detailed in a new study published in the journal Astronomy & and Astrophysics, the tunnel exists as an opening in a structure of hot gas that surrounds our solar neighborhood known as the […]
"This region stands out in stark relief thanks to the much-improved sensitivity of eROSITA and a vastly different surveying strategy compared to ROSAT," the space telescope's predecessor. The idea has faced challenges; decades ago, it emerged that an interaction between our Sun's solar winds and our planet's outer atmosphere could produce similar x-ray emissions, according to the researchers. Along with the interstellar tunnel, the detailed modeling of the Local Bubble revealed a temperature gradient across the structure, with the northern region notably hotter than the southern one.
