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

Ancient ‘white dwarf’ stars explode and die in more ways than was thought, and observing these violent cosmic deaths could help scientists to discover the invisible ‘dark energy’ that is powering the ...

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 ...

We live in an expanding Universe, and in the late 1990s, two independent teams of astronomers discovered—much to their surprise—that the expansion is accelerating. Whatever’s driving that ...

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

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 ...

If recent observations of cosmic acceleration are correct, then the "vacuum energy" that is emerging in the universe will continue to overtake the pull of gravity from matter. This means that ...
