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

The standard model of cosmology relies on an accurate reading of the cosmic microwave background. This radiation, emitted 380,000 years after the Big Bang, is considered proof of the theory's validity ...

The age of the Universe is now estimated at 13.8 billion years with increased precision. These advances pave the way for the future Simons Observatory, which will continue the study of the cosmic ...

Researchers believe something powerful unleashed the newly found neutrino, such as a gamma-ray burst or the interaction of cosmic rays with photons from the cosmic microwave background, which is ...

They have accomplished this, not in a laboratory, but in space, using a catalog of over half a billion galaxies imaged by NASA’s Wide-field Infrared Survey Explorer, which flew from 2010 to ...

Astrophysicist Paul Sutter illuminates the origin of ancient radiation leftover from the earliest moments of the universe; the flash of the Big Bang is still with us.

These detectors provide details about each cosmic ray, with signal timing indicating trajectory and the number of charged particles revealing the primary particle’s energy. Due to their charge, cosmic ...

It's the most energetic cosmic ray detected since 1991, when astronomers detected the so-called "Oh-My-God' particle, with energies of an even more impressive 320 EeV.
