WASHINGTON (Reuters) - New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and invisible cosmic force called dark energy - responsible ...

Scientists using NASA’s Hubble Space Telescope have discovered that dark energy is not a new constituent of space, but rather has been present for most of the universe’s history. Dark energy is a ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...

There is growing controversy over recent evidence suggesting that a mysterious force known as dark energy might be changing in a way that challenges our current understanding of time and space. An ...

DESI has made the largest 3D map of our universe to date. Earth is at the center of this thin slice of the full map. The magnified section visualizes the underlying structure of matter in our universe ...

Last spring, a team of nearly 1,000 cosmologists announced that dark energy — the enigmatic agent propelling the universe to swell in size at an ever-increasing rate — might be slackening. The ...
