The Sun Has a Hidden Magnetic Structure Scientists Can Finally See Oct 06, 2026

Show notes

A new view of the Sun is revealing that its magnetic canopy is far more intricate than scientists expected.
Using the Sunrise-III observatory and its high-resolution SCIP instrument from 35 kilometers above Earth, researchers captured delicate magnetic structures hidden above quiet solar regions. The observations could help explain how magnetic energy moves through the Sun’s atmosphere and contributes to its extreme heating.

How Supermassive Black Holes Control the Fate of Entire Galaxies Oct 02, 2026

Show notes

Supermassive black holes may control the growth of entire galaxies. New research shows that narrow plasma jets can travel hundreds of thousands of light-years, reaching the gas surrounding galaxies and creating directional regions of glowing ionized hydrogen.
By heating and disrupting this cold gas, black holes can suppress star formation and regulate how galaxies evolve. A tiny region at the center of a galaxy may ultimately shape its entire cosmic environment.
