Dark energy remains one of the most stubborn puzzles in modern science. Despite decades of observation and increasingly ...

The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is looking to create one of the largest maps of the universe by creating a catalog of Lyman-alpha-emitting galaxies. These galaxies, which ...

The most refined and comprehensive version of the technique that discovered dark energy has returned a new result that scientists are calling “tantalizing,” potentially hinting that dark energy may ...

The universe is expanding, and that expansion is accelerating. But what is causing that to happen? The leading hypothesis is a repellent force that astrophysicists refer to as “dark energy,” which ...

Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the universe hangs in the balance. The force is enormous — it makes up nearly 70% of ...

Physics is good at explaining many of our universe’s strange phenomena — from the way invisible beams of the light fan into rainbows to how rocket fuel can propel us into space. Even so, there are ...

In the late 1990s, two teams of astronomers were out to settle a score. Cosmologists had been at odds for over a decade in their quest to measure the total amount of matter and energy in the universe.

Robert Nichol is a member of the Dark Energy Survey collaboration. Dark energy is estimated to make up nearly 70% of the observable universe, yet we still don’t understand what it is. While its nature ...

In deciphering the cosmic puzzle of what the nature of dark energy is, we're going to better learn the fate of the Universe. Whether dark energy changes in strength or sign is key to knowing whether ...
