Astronomers Clock a Black Hole Spinning at Half the Speed of Light
The researchers analyzed data gathered by a number of instruments, including NASA's Chandra X-ray Observatory and Neil Gehrels Swift space telescopes, as well as the European Space Agency's XMM-Newton spacecraft. Estimating the spin has been tough to do until now. The victory here is the ability to use tidal disruption flares to constrain the spin. Once Pasham discovered the periodic signal,...

Hubble loses best camera but discovers brightest ever quasar
The light from quasar J0439+1634, about 12.8 billion light-years away, bends as it passes by a galaxy roughly six billion light-years away. "Quasar" is short for quasi-stellar radio source, and describes bright centres of galaxies. Co-author Fabian Walter, of the Max Planck Institute for Astronomy in Germany, said it was a prime candidate for further investigation. The intervening, or lensing,... [Full Article...]

Astronomers intercept mysterious repeating radio signals from space
Among them is Professor Avid Loeb, from the Harvard-Smithsonian Centre for Astrophysics in the U.S., who believes that they could be evidence of incredibly advanced alien technology. Artist's impression of the active galactic nucleus shows the supermassive black hole at the center of the accretion disk sending a narrow high-energy jet of matter into space , perpendicular to the disc in this image...
