RECENT DISCOVERY About Supermassive Black Holes Explained!
Summary
PBS Space Time explores the discovery of a black hole that has recently swiveled its particle jets to point directly at Earth, transforming it from a radio galaxy into a blazar. The episode explains how active galactic nuclei change appearance based on orientation and discusses how galaxy mergers or accretion disk shifts likely caused this dramatic reorientation. This rare event provides a new laboratory for studying the dynamic mechanisms behind astrophysical jets and black hole spin.
