Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge ...

Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the ...

Several discoveries have emerged from the commissioning phase of the new Vera C. Rubin Observatory in Chile, serving as an ...

About 85 percent of the matter in the universe is thought to be dark matter, yet there is still no confirmed direct detection of any dark matter particle. Ground-based detectors, space-based ...

Dark matter is so pervasive throughout galaxies that its presence explains the stability and motion of stars in systems such as the Milky Way. For example, current models indicate that our galaxy is ...

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 ...

The research team used two distributed sensors and leveraged two quantum resources for increasing detection sensitivity: squeezing, characterized by reduced quantum noise below the classical optical ...

Magnetic fields thread through galaxies, stretch across cosmic voids, and shape the behavior of charged particles over millions of light-years. Yet their origin remains one of the most stubborn ...

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 ...

Artistic representation of the Milky Way, where the innermost stars move at near relativistic speeds around a dense core of dark matter rather than a massive black hole at the center. Credit: ...

David Joffe receives funding from NASA through a grant from the Georgia Space Grant Consortium. Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer ...
