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 ...

The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids ...

About 13.8 billion years ago, the origin of the universe began with the Big Bang. Scientists say all space, time, matter, and energy emerged from a tiny, dense point. Today, the universe is still ...

In the name of open science, the multinational scientific collaboration COSMOS has released the data behind the largest map of the universe. Called the COSMOS-Web field, the project, with data ...

New observations from the James Webb Space Telescope (JWST) suggest the cosmos may be much older than once believed. For decades, scientists have held that the universe is about 13.8 billion years old ...

A team of researchers proposes a new vision of the Universe's first moments. Their model eliminates the need for traditional speculative hypotheses. Cosmologists have long worked with the inflation ...

Mind-bending materials called quasicrystals have an orderly structure, but without a regularly repeating pattern. They’ve been found in meteorites and the debris from the first atomic bomb test.
