A NASA mission has observed a supermassive black hole pointing its highly energetic jet straight toward Earth. Don't panic just yet, though. As fearsome as this cosmic event is, it's located at a very safe distance of about 400 million light-years away.
Blazar jets can stretch across space for millions of light-years, but the mechanisms that launch them aren't yet well-understood. However, these new discoveries surrounding the jet of Markarian 421 could shed some light on this extreme cosmic phenomenon. "Markarian 421 is an old friend for high-energy astronomers," lead researcher behind the discovery and Italian Space Agency astrophysicist, Laura Di Gesu, said in a statement.
As a result of these two effects, blazars can often outshine the combined light of every star in the galaxies that house them. And now, IXPE has used that light to paint a picture of the physics going on at the heart of Markarian 421's jet and even identify the glowing beam's point of origin. Even more remarkably, analysis of IXPE's data showed that the polarization of the jet dropped to 0% between its first and second observations. This showed the team the magnetic field was turning like a corkscrew.
