Scientists set to unveil first picture of a black hole

by Marlowe HOOD Agence France Presse Paris, France (AFP) — The world, it seems, is soon to see the first picture of a black hole. On Wednesday, astronomers across the globe will hold “six major press conferences” simultaneously to announce the first results of the Event Horizon Telescope (EHT), which was designed precisely for that purpose. It has been a long wait. Of all the forces or objects in the Universe that we cannot see […]

Milky Way core may harbour thousands of black holes: study

by Mariëtte Le Roux Agence France Presse PARIS, France (AFP) — Astrophysicists have detected a dozen black holes at the center of our Milky Way galaxy and said Wednesday there could be as many as 10,000. The find provides the first evidence for a long-held theory that the massive black hole at the core of every large galaxy should be surrounded by thousands of smaller ones, they wrote in the science journal Nature. “We observed […]

Black hole in a ‘bathtub’ makes waves for UK scientists

NOTTINGHAM, England (Reuters) — Scientists are unlocking the mysteries of black holes… in a giant bath tub at the University of Nottingham. A team from the Quantum Gravity Laboratory says they have successfully simulated the conditions around black holes and published the first statistical evidence of an effect known as super-radiance, whereby a wave hitting a rotating black hole can extract energy from it. They built a specially designed 3 metre by 1.5-meter tub with […]

Desert telescope stakes out supermassive black hole

by Laurence COUSTAL Mariëtte Le Roux PARIS, France (AFP) — First postulated more than 230 years ago, black holes have been extensively researched, frequently depicted, even featured in sci-fi films. We’ve all seen the artists’ impressions and read of their ravenous star-gobbling feasts. But here’s the thing… science is still not 100 percent sure what they look like, how they behave or even that they exist. Telescopes have never seen a black hole, and the […]

NASA: Black holes make perfect lab for dark matter

JULY 3 (Reuters) — A new NASA computer simulation made at the Goddard Space Flight Center in Maryland has revealed what scientists there believe to be gamma-ray light produced by the smashing of dark matter particles in the gravitational pull of a dark hole. The revelation allows scientists a new view into the elusive particle, which research astrophysicist Jeremy Schnittman says remains a mystery for much of the world. “I’ve long been interested in black […]
