For nearly three decades, astronomers have interpreted the faint luminosity of certain distant explosive stars as a sign of ...

For almost a century, we have known that the universe is expanding. For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates were the ...

By observing the brightness of distant dying stars, astronomers have long come to believe that the expansion of the universe ...

As if dark energy weren't already mysterious and baffling enough, new research suggests that this unknown force may not be ...

The universe's first galaxies were hot messes, according to a recent study. During their younger days, they were wild, ...

Evidence now suggests the universe’s expansion has started to slow, not speed up. The findings imply dark energy is weakening ...

Led by doctoral student Tatsuya Kotani and Professor Tomoharu Oka from Keio University, the research team measured the ...

The plot represents the new model with the x-axis and the y-axis showing the minimum sizes of collapsing and expanding regions that can impact cosmological measurements. The contours are independent ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...
