Black hole jets

A strong wind from a supergiant star deflects jets emitted from the black hole in the Cygnus X-1 system, causing them to change direction during their mutual orbit. Credit: International Centre for Radio Astronomy Research (ICRAR)

Black hole jets measured as powerful as 10,000 suns

  • One response
Radio observations in the Cygnus X-1 system have shown that the black hole's jets travel at about half the speed of light and carry about 10% of the energy of the material falling into it.

A record-breaking cosmic radio ring has been discovered – the most distant and powerful yet

  • No comments
Astronomers have identified RAD J131346.9+500320, a double-ring structure billions of light-years away, and suggest that black hole jets and superwinds shape such rare radio rings; two other radio giants have been found in galaxy clusters.
