As the Dark Energy Survey (DES) releases its final results, we caught up with two physicists who've been involved in the project from its early days. In this Q&A, Josh Frieman, DES co-founder and ...

What is dark energy? Why does dark energy seem to be weakening? Is our universe part of a larger multiverse? What lies beyond the boundary of a black hole? The universe seems to be rotating, and if ...

The six-year Dark Energy Survey has released its full results, showing that two leading models of cosmology are equally valid ...

Our universe does host life, but another one might be even better suited for life. Here’s what you’ll learn when you read ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

(CNN) — New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe.

The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size about 11 billion ...

Cosmologists are finally beginning to sketch a coherent picture of the universe we cannot see, using exquisitely detailed maps of galaxies, ghostly light and the large scale structure of space itself.

The Dark Energy Survey collaboration is releasing results that, for the first time, combine all of the data from an intensive six-year mapping of galaxies in the universe. The new analysis, of ...

Last year, the Dark Energy Spectroscopic Instrument (DESI) released its most detailed map of the universe yet. And with it, ...

(CNN) — New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe.

Calculating the total mass of the universe is not simple, because most of the mass is invisible. In a pie chart of the contents of the universe, only 5 percent is normal matter, atoms that make up all ...
