The Hubble tension is especially troubling because it involves two sets of measurements that offer conflicting views of the ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

Knotted structures once imagined by Lord Kelvin may actually have shaped the universe’s earliest moments, according to new ...

FROSTI is a new adaptive optics system that precisely corrects distortions in LIGO’s mirrors caused by extreme laser power.

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...

Scientists flew the XL-Calibur telescope on a high-altitude balloon to measure polarized X-rays from Cygnus X-1. These measurements reveal details about the chaotic, superheated material swirling ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

Researchers discovered that copper oxide catalysts form metallic copper mid-reaction, triggering a dramatic boost in ammonia output. The insight offers a roadmap for designing cleaner, more efficient ...

Scientists have uncovered a surprising second type of lion roar, using AI to decode vocal signatures with remarkable precision. This breakthrough sheds new light on how lions communicate and offers a ...

Around 115 million years ago, northern Australia’s seas hosted a colossal shark that rewrites what we thought we knew about early ocean predators. New fossil discoveries show that modern-type sharks ...

Scientists discovered that deep earthquake faults can heal far faster than expected, sometimes within hours. Slow slip events in Cascadia reveal repeated fault movements that only make sense if the ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” ...
