VISIONS of leaving Earth and launching humanity further into the cosmos are enough to get anyone starry-eyed. But the ...

astronomers Paul Murdin and Louise Webster surmised that a known galactic X-ray source called Cygnus X-1 was, in fact, a black hole. Though we haven’t known about these awe-inspiring objects for ...

The breakthrough offers new insights into the feeding mechanisms of black holes, from stellar-mass systems like Cygnus X-1 to supermassive giants at the centers of distant galaxies. If you’ve ...

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 ...

The composite image of NGC 1275, or Perseus A, reveals its dynamic structure by blending optical, radio, and X-ray data. Cygnus X-1, about 10,000 light-years away, is a powerful black hole pulling ...

In fact, these strong X-ray emissions led to the discovery of the first black hole, Cygnus X-1 in the constellation Cygnus, in 1964. If all this sounds like science fiction, read on. It's only the ...

Working off of Albert Einstein’s theory of gravity, the Australian physicist Ludwig Flamm suggested that a spacetime conduit could connect one side of a hole to the other. While black holes suck ...

This could explain the differences between the black holes at the centre of active galaxies (like Cygnus A) and their less active cousins (like our own Milky Way): the presence or absence of a ...

"Lurking in our galaxy, approximately 6,000 light-years from Earth, is a monster black hole named Cygnus X-1," Nasa explains. "Don’t get too close, or you’ll become its next meal!" CygnusX-1 ...
