New 3D Map of Local Hot Bubble Reveals Interstellar Tunnel to Superbubble

Astronomers have crafted a detailed three-dimensional map of the Local Hot Bubble (LHB), a vast, low-density region surrounding our solar system. This bubble, filled with hot, X-ray-emitting gas, has been a subject of study since the 1970s, and recent data from the eROSITA All-Sky Survey has provided new insights into…

NASA’s Chandra Telescope Observes Mysterious ‘Knots’ Blasting from Nearby Black Hole Jets

A recent study of black hole jets from NASA’s Chandra X-ray Observatory has identified bright formations or “knots” in these jets, with each showing unexpected variations in speed. This analysis, led by David Bogensberger, an astrophysicist at the University of Michigan, examined decades-old Chandra data on the supermassive black hole…
