Astronomers have discovered that planets can survive without stars, drifting as rogue or hypervelocity worlds. Some are flung into space by black holes, while others are displaced by gas giants. On ...

Runaway electron beams, generated during high-voltage nanosecond discharges in gases, represent a dynamic field of research in plasma physics and high‐energy processes. Under extreme electric fields, ...

The James Webb Space Telescope has confirmed the first runaway supermassive black hole, moving at 2.2 million mph through the Cosmic Owl galaxies. Pushing a galaxy-sized shockwave and leaving a long ...

Terrestrial gamma‐ray flashes (TGFs) are brief, intense bursts of high‐energy radiation emitted from thunderclouds, often coinciding with lightning discharges. These phenomena are now understood to ...
