Solar Eruption's Magnetic Field 'Heard' for the First Time

By the frequency of radio waves from a cloud of solar gas, scientists directly measured its magnetic field. It turns out that the invisible force is hidden in tangled clumps, not evenly smeared across the cloud.

Polarization Echo: Light Catches the Gravitational Ringing of a Black Hole

A covariant approach has been developed, showing that light in the gravitational "storm" of merging black holes alters its polarization, tracing the damped melody of the ringdown. Numerical simulations based on Kerr perturbation theory confirm: an achromatic rotation of ~10 degrees is a direct impri

Shadow of a Shaggy Beast: How Scalar Hair Shatters a Black Hole’s Image

The stronger the scalar field around a black hole, the more distorted its shadow. New simulations reveal that at extreme values, the shadow fractures into crescent-shaped shards.

The Universe's Radio Concert: How 30 Seconds of Silence Are Changing Physics

Using the OVRO–LWA array, astronomers conducted an unprecedented survey in the 50–86 MHz band with 10 Hz resolution. The 30-second exposure produced over three million images, setting strict limits on the power of hypothetical transmitters around nearby stars. No extraterrestrial signal was detected
