Approximately 4.5 million years ago, the Sun nearly intersected with two bright stars in Canis Major, whose intense radiation likely caused a ghostly, irradiated 'scar' in our galaxy's local interstellar medium, helping explain the current high ionization levels of helium around our solar system.
Astronomers using the eROSITA space telescope have discovered an 'interstellar tunnel' towards the constellation of Centaurus, potentially linking our Local Bubble to a neighboring superbubble. This tunnel, filled with hot plasma, was identified through improved sensitivity in X-ray mapping, revealing a gap in the cooler interstellar medium. The discovery adds complexity to our understanding of the Local Bubble's formation, believed to be shaped by supernova explosions. Further studies are needed to clarify the tunnel's properties and its connection to the Loop I superbubble.
Astronomers have discovered an 'interstellar tunnel' within the Local Hot Bubble, a massive structure of hot gas surrounding our solar system, which may connect to a larger bubble and form part of a galaxy-spanning network. Using data from the eROSITA telescope, researchers created a 3D model of the Local Bubble, revealing new features and supporting the theory that it was formed by supernova explosions millions of years ago. This discovery suggests a complex network of interstellar medium across the Milky Way.
