For the first time in history, we can explore the universe through a rich blend of senses—seeing, touching, and hearing astronomical data—in ways that deepen our understanding of space. While ...

The potential finds could be contributing to some of the faintest light we can see in the universe, say researchers.

Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

New observations of the cosmos show that the dark energy, a mysterious force that accelerates the expansion of the universe, ...
