It is situated near a supermassive black hole that weighs about 20 billion times more than our Sun. The quasar, APM 08279+5255, emits an extraordinary amount of energy—equivalent to that ...

Astronomers know that if they spot an incredibly luminous quasar, it means a rapidly growing supermassive black hole also is present, and J0529-4351 is the most impressive yet on both counts ...

Beyond its significance as the oldest-known X-ray quasar, UHZ1 offers compelling proof that the early universe is “seeded” with heavy black hole seeds with large birth masses that likely formed from ...

This particular quasar, called J1342+0928, is one of the most distant ever spotted at nearly 30 billion light years away. It formed less than 700 million years after the big bang.

With the help of two extremely bright quasars located more than 7 billion light-years away, researchers recently bolstered the case for quantum entanglement — a phenomenon Einstein described as ...

When X-rays (blue color) illuminate onto an iron atom (red ball at the center of the molecule), core-level electrons are excited. X-ray-excited electrons are then tunneled to the detector tip ...

Atom Computing is now using the system internally and plans to open it up for public use next year. The system has moved from a 10×10 grid to a 35×35 grid, bringing the potential sites for atoms ...

This artistic visualization shows J0313-1806, the most distant (and therefore earliest) quasar ever found. (Image credit: NOIRLab/NSF/AURA/J. da Silva) A record-breaking quasar While this newfound ...

The quasar 3C 273 appears starlike in this optical image taken by the Hubble Space Telescope. In reality, the light comes from the accretion disk around a supermassive black hole.
