To explore this long-standing mystery, an international team of scientists formed a group known as the Collaboration for ...

The events surrounding the Big Bang were so cataclysmic that they left an indelible imprint on the fabric of the cosmos. We can detect these scars today by observing the oldest light in the universe.

The earliest galaxies may have scrambled our reading of the Universe. A new study challenges the traditional interpretation of the cosmic microwave background, this fossil light from the Big Bang.

"By reproducing relativistic plasma conditions in the lab, we can measure processes that shape the evolution of cosmic jets and better understand the origin of magnetic fields in intergalactic space." ...

New telescope instruments now reveal distant galaxies in detail, reshaping how astronomers map dark matter, star formation, ...

Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA’s Integral gamma-ray observatory have tried an unusual method: ...
