Most scientists think that everything that we know and experience began with the Big Bang, 14 billion years ago. But how can ...

Scientists have tested gravity across some of the largest structures in the universe and found that it behaves exactly as predicted by long-standing physical laws. Researchers led by University of ...

Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and theoretical physicists, it is also a vexing invisible architect that ...

A nearby galaxy is behaving strangely—and now scientists know why. The Small Magellanic Cloud’s stars move in chaotic patterns because it slammed into its larger neighbor millions of years ago. That ...

Scientists found one of the earliest known slow-spinning galaxies, challenging long-standing ideas about how massive galaxies ...

Dark matter remains one of the most intriguing components of the cosmos, making up about 27% of the universe's total mass-energy content. It cannot be seen directly, yet its presence is inferred ...

Cold gas does not look dramatic at first glance. Neither does dust. Yet those two quiet ingredients sit at the center of a new effort to build a far more realistic picture of how galaxies formed. They ...
