Here’s what you’ll learn when you read this story: Cosmologists have long assumed that our expanding universe is isotropic, meaning it looks the same when viewed from any angle. Researchers found that ...

This updated model focuses on how the density of dark energy and the pace of star formation work together to influence the chance of life emerging. This Hubble Space Telescope image captures a ...

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 new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...

Dark energy is still one of the greatest cosmic mysteries. For all the time, money and telescopes that humanity has used to uncover its nature, scientists are still asking a fundamental question: What ...

A recent paper claimed that dark energy might not exist. But new research suggests this conclusion was premature.

In the Big Bend region, a portal to the early universe is enabled by the largest dark-sky reserve on Earth. The Hobby-Eberly Telescope at the McDonald Observatory in Fort Davis, Texas, was used to ...

But it was data from the first year of DESI, which showed the dark energy density tracking the rate of star formation, that convinced Croker and Farrah to join forces with the DESI Collaboration.

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It’s so well understood that ...

What if some black holes aren’t black holes at all? A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon. Instead, the ...
