New observations support the idea that hot, diffuse threads of gas called cosmic filaments connect clusters of galaxies ...

The expanding universe is one of the most fascinating and far-reaching discoveries in modern science. At its core lies a ...

The standard model, although successful in the explanation of cosmic microwave background radiation and the large-scale structure of the universe, relies on unobservable entities such as inflationary ...

The South Pole Telescope has released its most precise image yet of the universe’s first light—the cosmic microwave background. This new ground-based data confirms cosmic expansion anomalies and ...
