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 ...
As the Dark Energy Survey (DES) releases its final results, we caught up with two physicists who've been involved in the project from its early days. In this Q&A, Josh Frieman, DES co-founder 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 ...
At times, the sun ejects energetic material into space, which can have consequences for space-based and even ground-based ...
New observations from the James Webb Space Telescope have revealed unexpected features in the early universe, including ...

This awkward cosmic ingredient is forcing cosmologists to start over
Cosmology’s neat story of a universe driven apart by a simple, invisible “cosmic fuel” is starting to fray. A growing body of ...
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 ...
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 ...
