Astronomers Uncover Interstellar Tunnel Near Solar System

Researchers from the Max Planck Institute for Extraterrestrial Physics have discovered an 'interstellar tunnel' within the Local Hot Bubble (LHB) using data from the eROSITA All-Sky Survey. This tunnel, located towards the constellation Centaurus, may connect the LHB to neighboring superbubbles, forming a network of hot gas. The LHB, a 1,000-light-year-wide cavity filled with million-degree gas, is believed to have been shaped by supernova explosions. The eROSITA telescope's position allows for clearer observations, overcoming challenges posed by Earth's atmosphere.

Early Discovery: Carbon-Based Molecules Emerge Shortly After Big Bang

The James Webb Space Telescope (JWST) has discovered evidence of carbon-based molecules and dust existing just a billion years after the Big Bang, challenging previous assumptions about the early Universe. The dust observed in the early galaxies studied by JWST appears to consist of graphite or diamond-like grains, similar to those observed in later cosmic history. Astronomers speculate that these diamond-like grains may have come from debris ejected in supernova explosions or from Wolf-Rayet stars, which are known to be efficient dust producers. The discovery provides insights into the earliest stellar populations and the formation of dust in the Universe.
