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.

Pulsar's twinkle reveals the hidden fabric of space

  • No comments
SETI Institute observations of the Allen Telescope Array over about 10 months have shown how the twinkling of pulsars varies over time, creating tiny delays that require correction in precise timing measurements. The subtle twinkling of a pulsar reveals

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.
