Astronomers may have found an exciting new clue about dark energy—the mysterious force driving the universe’s accelerating expansion. They discovered an extraordinarily bright supernova from more than ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...
