Dark energy remains one of the most stubborn puzzles in modern science. Despite decades of observation and increasingly ...

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 ...

CERN's ALICE collaboration reveals how fragile deuterons survive high-energy collisions, impacting models of cosmic rays and ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

New observations from the James Webb Space Telescope have revealed unexpected features in the early universe, including ...

As the Dark Energy Survey (DES) releases its final results, we caught up with two physicists who've been involved in the ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

We are zeroing in on the true composition of the rarest, highest-energy cosmic rays – which could help reveal their unknown origins. Previous ultra-high-energy cosmic ray detections – by the Pierre ...

A new study from NYU Abu Dhabi has found that high-energy particles from space, known as cosmic rays, could create the energy needed to support life underground on planets and moons in our solar ...
