First discovered in 1998 by analyzing distant Type 1a supernovae using the Hubble Space Telescope (a discovery that eventually won the Nobel Prize in Physics in 2011), this perceivable expansion isn’t ...

Dark energy, one of the most mysterious concepts ... However, in 1998 the Hubble Space Telescope measured the distances between distant galaxies and found that the universe was currently expanding ...

"We find that, in fact, early dark energy is a very elegant and sparse solution to two of the most pressing problems in cosmology." The so-called Hubble tension arises from the fact that there are ...

The current model of universe expansion is complicated by “Hubble tension,” an anomaly in which evidence from the afterglow of the Big Bang (known as the Cosmic Microwave Background) shows that the ...

Dark energy is one of the greatest mysteries of the universe. This mysterious force is thought to be accelerating the expansion of the cosmos. But a new study challenges this long-held belief.

Despite nearly a hundred years of astronomical measurements and calculations, scientists still can’t agree on the exact value of the Hubble constant. The true number could reveal missing pieces in our ...

which relies on dark energy to account for the universe's observed behavior. The study also offered a potential resolution to the long-standing "Hubble tension," a discrepancy between observed and ...

Hubble and its fellow observatories give us ... The telescope was also instrumental in the discovery of dark energy, a little-known but ubiquitous force that works against gravity and contributes ...

Scientists from the University of Canterbury propose the "timescape model," explaining expansion without invoking dark energy, published in Monthly Notices of the Royal Astronomical Society Letters.

This is called Olbers' Paradox ... a dark one? Modern explanations suggest the universe is finite, has an age, and is expanding faster and faster, which (according to a discovery by Edwin Hubble ...
