Black Hole Images Could Test Einstein’s Gravity in Cleaner Detail
Why Next-Generation Black Hole Images Matter As telescope technology and techniques improve, scientists anticipate sharper pictures of black holes than ever before. The next wave of high-resolution images will push the boundaries of how we study gravity in the most extreme environments. These observations could either solidify Albert Einstein’s theory of general relativity or uncover…

M87* Magnetic Field Flips Reveal Dynamic Cosmic Weather
Overview: A Dynamic Magnetic Field Around a Stable Shadow Using observations from the Event Horizon Telescope (EHT) in 2017, 2018, and 2021, scientists have mapped how the polarization of light around M87* reveals changes in the magnetic field near the black hole’s edge. The results show that while the black hole’s shadow—the dark ring carved…

The First Black Hole We Saw Changes Its Magnetic Weather: M87*’s Dynamic Magnetism
M87*: A Supermassive Black Hole With Dynamic Magnetic Weather When scientists released the first image of a black hole in 2019, the focus was on the shadow and the surrounding glow. But new time-series data from the Event Horizon Telescope (EHT) reveal something equally dramatic and unexpected: the magnetic field near M87*’s edge is not…

M87* Magnetic Field Changes Reveal Dynamic Black Hole Weather
Overview: A Black Hole’s Weather, Not Just Its Shadow The first image of a black hole, captured by the Event Horizon Telescope (EHT) in 2019, made M87* a household name in astronomy. But new time‑domain observations—from 2017, 2018, and 2021—reveal that the environment around this giant object is far less static than the shadow on…
