Dark matter remains one of the most compelling enigmas in modern cosmology. Although it does not emit light, its gravitational influence is essential for the formation and evolution of cosmic ...

About a year after launching into orbit around the Sun, the James Webb Space Telescope began imaging an abundance of little red dots, which scientists called, um, “little red dots.” I know—not only is ...

As part of the Decadal Survey on Astronomy and Astrophysics (Astro2020), the Panel on Cosmology will identify and articulate the scientific themes that will define the frontier in cosmology research ...

Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called “impossible early galaxy problem.

Quantum gravity and cosmology represent a frontier in theoretical physics where the principles of quantum mechanics are integrated with the framework of general relativity. This synthesis is crucial ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...
