NASA is preparing to send a new space telescope into orbit that the agency says could dramatically expand what scientists ...

Dark energy remains one of the most stubborn puzzles in modern science. Despite decades of observation and increasingly powerful telescopes, its true nature is still unknown. Now, scientists involved ...

After 25 years of planning, six years of data collection, and six more years of analysis, scientists have published a portion of the final results of the Dark Energy Survey (DES) — the largest, most ...

A massive cosmic milestone has just been reached: scientists have completed the largest high-resolution 3D map of the universe ever created. Built using data from over 47 million galaxies and quasars, ...

Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing ...

Cosmologists have long struggled to determine whether the universe's accelerating expansion is being driven by a simple cosmological constant, or whether dark energy's influence is evolving over time.

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 ...

In a significant milestone, the Dark Energy Spectroscopic Instrument (DESI) has completed its 3D map of the Universe—the highest resolution of any such map yet achieved—on schedule and with more data ...

Scientists have been gifted with a clearer picture of the expansion of the universe and dark energy, the mysterious force driving the acceleration of this expansion, than ever before. This comes ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...
