Ancient ‘white dwarf’ stars explode and die in more ways than was thought, and observing these violent cosmic deaths could ...

A unique dataset of Type Ia supernovae being released today could change how cosmologists measure the expansion history of ...

It was thought to be accelerating the expansion of our universe, but some experts now question this assumption. This immense energy constitutes nearly 70% of the entire universe. To put it into ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

Astronomers have proposed a new theory to suggest why our universe is expanding at an accelerating rate. That our universe is expanding, is in wide agreement, though how exactly that process ...

Dark energy is still a mystery, but powerful new telescopes are set to uncover clues. With NASA and ESA leading the charge, ...

Fundamental physics, dark energy, matter, and universe expansion will be explored during a free lecture offered to high ...

The rate of warming in the oceans has more than quadrupled since 1985, suggesting global warming in general has undergone a ...

Scientists have come a step closer to understanding how collisionless shock waves -- found throughout the universe -- are able to accelerate particles to extreme speeds. Scientists have come a ...
