This is the light echo of the Big Bang, the first light that freely moved through the universe. This relic is crucial to our ...

Scientists have many big questions to tackle about the universe, including how big it actually is. But even the proposed ...

Physicists have determined that most of the universe is dark matter -- invisible to us but affecting the universe anyway.

A new study casts doubt on the universe’s accelerating expansion, suggesting dark energy might be weakening over time.
