The Dark Energy Camera has captured a vibrant view of the Corona Australis Molecular Cloud, with the star-forming region ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the ...

What’s most of the universe made of? The answer isn’t stars, galaxies, or even dark matter. Instead, over two-thirds of the universe is energy — a mysterious form of it that is pushing the universe ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have to use indirect evidence, like the explosions of Type Ia supernovae, to investigate the impacts of dark energy.

A peer-reviewed paper published in The Astrophysical Journal Letters argues that black holes gain mass in step with the ...

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 universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

Radio astronomers have directly measured the distance to a faraway galaxy, providing a valuable “yardstick” for calibrating large astronomical distances and demonstrating a vital method that could ...

For decades, astronomers have believed that dark matter and dark energy make up most of the universe. However, a new study suggests they might not exist at all. Instead, what we perceive as dark ...

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of years ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe's greatest mysteries. The most widely accepted theory currently suggests ...
