| Mini-jet found near Milky Way's supermassive black hole Posted: 09 Dec 2021 05:16 PM PST Our Milky Way's central black hole has a leak. This supermassive black hole looks like it still has the vestiges of a blowtorch-like jet dating back several thousand years. NASA's Hubble Space Telescope hasn't photographed the phantom jet but has helped find circumstantial evidence that it is still pushing feebly into a huge hydrogen cloud and then splattering, like the narrow stream from a hose aimed into a pile of sand. |
| Machine learning decodes tremors of the universe Posted: 09 Dec 2021 11:25 AM PST Researchers train a neural network to estimate -- in just a few seconds -- the precise characteristics of merging black holes based on their gravitational-wave emissions. The network determines the masses and spins of the black holes, where in the sky, at what angle, and how far away from Earth the merger took place. |
| How plasma swirling around black holes can produce heat and light Posted: 09 Dec 2021 11:25 AM PST Researchers have uncovered a process in the swirling masses of plasma surrounding black holes and neutron stars that can cause previously unexplained emissions of light and heat. These findings can increase basic understanding of fundamental astrophysical processes throughout the universe. |
| Quest to deliver ultra-fast and energy efficient magnetic recording moves step closer Posted: 09 Dec 2021 11:25 AM PST The quest to deliver ultra-fast and energy efficient magnetic recording could be a step closer to fruition, due to pioneering new research on all-optical switching of magnetization. |
| A new super-cooled microwave source boosts the scale-up of quantum computers Posted: 09 Dec 2021 09:44 AM PST Researchers have developed a circuit that produces the high-quality microwave signals required to control quantum computers while operating at temperatures near absolute zero. This is a key step towards moving the control system closer to the quantum processor, which may make it possible to greatly increase the number of qubits in the processor. |
| Citizen scientists find young-Jupiter-like object missed by previous exoplanet searches Posted: 09 Dec 2021 09:42 AM PST Citizen scientists have discovered a new object orbiting a Sun-like star that had been missed by previous searches. The object is very distant from its host star -- more than 1,600 times farther than the Earth is from the Sun -- and is thought to be a large planet or a small brown dwarf, a type of object that is not massive enough to burn hydrogen like true stars. |
| Success in visualizing the propagation path of electromagnetic waves from space to ground Posted: 09 Dec 2021 06:56 AM PST Using data on electromagnetic (EM) waves and plasma particles measured simultaneously via multiple satellites, an international collaborative research group has discovered the existence of invisible 'propagation path' of EM waves and elucidated the mechanism by which EM waves propagate to the ground. |
