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

If scientists confirm an anisotropic expansion, it would challenge the assumption that the universe has no preferred directions.

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 ...

This illustration depicts NSF–DOE Vera C. Rubin Observatory capturing light from supernovae, the explosive deaths of massive stars. These cosmic beacons are important for studying the expansion of the ...

The Hubble tension grows: new data shows the Universe’s expansion defies current physics models, suggesting our understanding of cosmology may need a major overhaul. Credit: SciTechDaily.com New ...

June 30, 2021 — Our universe is expanding, but our two main ways to measure how fast this expansion is happening have resulted in different answers. An astronomer gives an overview of the most ...

The universe appears to be expanding at a staggering speed, much faster than expected. A recent study reinforces this observation, confirming an expansion that contradicts current theoretical models.

The expansion rate of the Universe has befuddled and concerned researchers for decades. Recent measurements have only added to the mystery and heightened the alarm within the scientific community, ...

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.
