A couple of weeks ago, the Event Horizon Telescope (EHT) collaboration has revealed, for the first time, the black hole image of the M87 in polarized light. This is the next big step closer to better understanding how accreting materials evolve and how M87 launches the energetic jets, which extend at least 5000 light-years. Light becomes polarized when it propagates through filters like the lenses of polarized sunglasses. Such sunglasses have been used to protect our eyes and enhance our vision by reducing the glare of the sun or the reflected light. Likewise, we can see better the region around the black hole from the polarized light, which is emitted…
