New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure ...

Physicists have taken the Universe’s temperature, revealing the searing trillion-degree heat of the Big Bang’s first plasma.

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

Astronomers may have misread cosmic acceleration for 27 years. The universe may be slowing down, not speeding up.

Trace the universe’s 13.8 billion-year history in ten minutes and explore cosmic evolution.

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

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

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

For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates ...

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 ...

In a first-of-its-kind experiment, scientists have recreated "cosmic fireballs" here on Earth in a particle accelerator.The ...

Collaborative experiments focus on uncovering the unusual properties of the ghost particle. In a recent study, physicists have created the clearest and most detailed view so far of how neutrinos shift ...
