Instead of lenses, though, it is magnetic fields in hot regions of space that polarize astronomical light. When you measure light emanating from an astronomical source, sometimes some of it is polarized, in the same way the light going through a pair of polarized sun glasses is. The newly published polarized images are key to understanding how the magnetic field allows the black hole to вЂeatвЂ™ matter and launch powerful jets. We are now seeing the next crucial piece of evidence to understand how magnetic fields behave around black holes, and how activity in this very compact region of space can drive powerful jets that extend far beyond the galaxy.ДЄnother astronomer involved in the project вЂ“ Andrew Chael at the Princeton Center for Theoretical Science вЂ“ further explained:

Astronomer Monika Moscibrodzka of Radboud University in the Netherlands said in a statement: These observations are a key to understanding how this occurs, these astronomers said. The black hole in M87 sends out enormous jets вЂ“ matter ejected at nearly the speed of light вЂ“ from its core. The astronomers published their results in two papers ( here and here) in the peer-reviewed Astrophysical Journal Letters on March 24, 2021, with a third one accepted for publication soon ( here). The polarization of the light gives astronomers a signature (a representation) of a black holeвЂ™s magnetic field, for the first time. On March 24, 2021, the Event Horizon Telescope вЂ“ the same global collaboration that captured M87вЂ™s black hole вЂ“ released a new image showing polarized light from this black hole. The black hole was a supermassive one вЂ“ millions of times our sunвЂ™s mass вЂ“ at the heart of a relatively nearby galaxy known as M87. In 2019, astronomers released the first direct image of a black hole, a feat that made headlines and boggled minds all over the world. Thus, for the first time, we have an image showing the вЂњsignatureвЂќ of magnetic fields around a black hole. The lines indicate the orientation of polarized light, which is directly related to the black holeвЂ™s magnetic field lines. The Event Horizon Telescope collaboration вЂ“ a global network of radio dishes вЂ“ observed it. This is an image of polarized light in the vicinity of the supermassive black hole at the center of galaxy M87.
