Astronomers have, for the first time, directly measured the instantaneous power of jets blasting from a black hole system, ...

An extreme cosmic dance is unfolding in the binary system Cygnus X-1, 7,000 light-years away from us. There, a stellar black ...

For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.

Since its discovery 45 years ago, Cygnus X-1 has been one of the most intensively studied cosmic X-ray sources. About a decade after its discovery, Cygnus X-1 secured a place in the history of ...

The first black hole to be confirmed, Cygnus X-1, is blasting "dancing jets" into space with the force of 10,000 Suns. While its discovery in 1964 came at a time when scientists still questioned if ...

More than 60 years after astronomers first detected its X-ray glow, Cygnus X-1 — the first black hole ever confirmed — is still revealing secrets. Researchers have now measured something that long ...

Astronomers directly measured the power of jets from black hole Cygnus X-1, confirming decade-old UW–Madison predictions ...

A black hole on a list of the best deep-sky targets? That sounds like an oxymoron! But for the observer who likes to track down the unusual, this is an ideal target. In a telescope, Cygnus X-1 looks ...

As matter swirls violently down toward the event horizon of a black hole, it forms an accretion disk, heating plasma to millions of degrees and blasting X-rays into space. But what exactly does the ...
