Time to put Billy Ray Cyrus and Elizabeth Hurley on the Mount Rushmore of confusing Hollywood couples who have entered the zeitgeist with absolutely no notice—in bunny ears no less. It has only been a ...

Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries ...

Cosmic rays, high-energy particles that travel through space, have puzzled scientists for decades. One particular feature of their energy spectrum—the “knee”—has long remained a mystery. Recent ...

Using intense X-rays, researchers captured a buckyball as it expanded, split and shed electrons under strong laser fields. Detailed scattering measurements showed how the molecule behaves at low, ...

For decades, a sharp kink in the energy spectrum of particles raining down from space has taunted astrophysicists, hinting at powerful engines in our Galaxy but refusing to reveal their identity. Now ...
