First Glimpse Inside a White Dwarf Binary’s Innermost Region
Unveiling a Cosmic Dance: The Innermost Region of a White Dwarf Binary About 200 light-years from Earth, a dramatic celestial pairing is offering scientists a rare glimpse into the extreme physics at the heart of a white dwarf binary. In this system, a dense, magnetized white dwarf siphons material from a larger companion star, creating…

ESA’s Solar Orbiter Captures First Close-Up of Sun’s Magnetic Engine in Motion
Overview: A New Window into the Sun’s Magnetic Engine The European Space Agency’s Solar Orbiter has delivered a groundbreaking glimpse into the Sun’s magnetic heart. For the first time, scientists have observed a high-resolution view of the Sun’s magnetic field near its south pole, offering clues about how magnetic energy is stored, twisted, and released…

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…
