The cosmic couple Cygnus X-3 intrigues researchers. Located 32,000 light-years away, this system, composed of a compact ...

In a "rite of passage," the JAXA/NASA X-ray telescope XRISM has mapped in detail Cygnus X-3, a curious binary system with a ...

NASA's IXPE (Imaging X-ray Polarimetry Explorer) has helped astronomers better understand the shapes of structures essential ...

XRISM’s detailed study of Cygnus X-3, a unique binary system 32,000 light-years away, reveals complex gas dynamics driven by ...

What Was the First Black Hole Ever Discovered? The first accepted black hole was Cygnus X-1. Discovered during a 1971 rocket flight, Cygnus X-1 is one of the strongest X-ray sources detectable ...

It's a place so far out our minds twist and bend when trying to process the number: one billion light years away, in a constellation called Cygnus. The galaxy has at its core two black holes that ...

Cygnus X-3 is a high-mass binary consisting of a compact object (likely a black hole) and a hot Wolf-Rayet star. This artist's concept shows one interpretation of the system. High-resolution X-ray ...

AT 2021hdr is a binary supermassive black hole (BSMBH) system in the center of a galaxy 1 billion light-years away, in the Cygnus constellation. In 2021, researchers observing it using NASA’s Zwicky ...

The dual black holes are in the center of a galaxy called 2MASX J21240027+3409114, located 1 billion light-years away in the northern constellation Cygnus. The pair are about 16 billion miles (26 ...

The Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory has captured the most detailed portrait yet of gases ...

Cygnus X-3 is also shrouded in gas streaming from its massive star occupant. X-rays from around the suspected black hole ionize this gas envelope, causing the material to emit X-rays itself.
