Recent findings suggest that dark energy may not be a fixed constant but could evolve. It has led scientists to theorize that ...

Using the largest catalog of exploding white dwarf vampire stars ever gathered has provided further evidence that dark energy ...

NASA’s Roman Space Telescope is set to embark on a deep-sky survey that could capture nearly 100,000 cosmic explosions, ...

It took about 50 exploding stars to upend cosmology. Researchers mapped and measured light from Type Ia supernovae, the ...

Type Ia supernovae are stellar explosions used to measure the universe's expansion. These explosions result from white dwarfs exceeding a critical mass, causing them to reignite and explode. Two ...

When researchers use this Planck data to estimate the expansion of the universe, based on our understanding of the universe as it existed when it was young, they honed in on a figure for the ...

JWST takes a jab at the mystery of the universe’s expansion rate The powerful space telescope's precise measurements confirm we have a problem. Briley Lewis Oct 3, 2023 12:00 PM EDT ...

Before the telescope was launched, scientists knew that the universe was expanding, but they didn’t know how fast this expansion was happening. Findings from Hubble in the 1990s pinned this ...

Type Ia Supernovae are the dramatic explosions of white dwarf stars at the ends of their lives. Cosmologists use them to probe distances across the universe by comparing their fluxes, as further ...

The Hubble telescope just made its best measurement yet of the universe's current expansion rate, but it still doesn't match the early universe. When you purchase through links on our site, we may ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
