Ever since humans first gazed up at the night sky, the Universe has filled us with awe and wonder. Lately, however, it's also ...

In the early universe, moments after the Big Bang and cosmic inflation, clusters of exotic, massive particles could have ...

The detection of gravitational waves in 2023 revealed a cosmic event that seemed to overturn known laws of astrophysics, ...

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

The study of black holes within the framework of General Relativity has long been enriched by investigations into angular momentum inequalities. These inequalities serve as geometrical constraints ...

Here’s what you’ll learn when you read this story: Black holes usually form from stars that burn out and collapse in on themselves, but that cannot explain the red spark of light that could be a ...

When black holes need a place to crash, they prefer a nice, bright quasar. So says Chiara Mingarelli, an assistant professor of physics in Yale’s Faculty of Arts and Sciences and a key member of an ...

A sweeping new study has pulled back the curtain on the chaotic early lives of young stars, revealing that stellar infancy is far more turbulent and variable than previously thought. Over ten ...
