The cosmic doppelgangers seen in the fascinating space wallpaper make up a double quasar known as QSO 0957+561, also known as the "Twin Quasar", which lies just under 14 billion light-years from ...

The most powerful cosmic ray, named the Oh-My-God particle, was detected more than 30 years ago and measured around 320 exa-electron volts (EeV) when it was discovered.

It rivals the single most energetic cosmic ray ever observed, the “Oh-My-God” particle that was detected in 1991, the study found. Cosmic rays are charged particles that travel through space ...

This striking cosmic whirl is the center of galaxy NGC 524, as seen in this fascinating space wallpaper. This galaxy is located in the constellation of Pisces, some 90 million light-years from Earth.

A cometary globule, named CG 4, is the cosmic phenomenon that resembles a ghostly hand seemingly reaching toward a spiral galaxy in a new image taken by the Dark Energy Camera.

It's being nicknamed "God's hand." It's about 1,300 light years away from Earth.The picture was taken by the Dark Energy Camera, which is mounted on a telescope in Chile.The image shows a cometary ...

Researchers recently detected an "ultra-high-energy" cosmic ray, which is the most powerful since the famous "Oh My God" particle was detected in 1991. They have no idea where it came from.
