A tiny, dense stellar corpse in a nearby galaxy is pumping out so much energy that, on paper, it should have blown itself ...

At times, the sun ejects energetic material into space, which can have consequences for space-based and even ground-based ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the ...

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 ...

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 ...
