In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, or simply N159, located 161,000 light-years away in the Large Magellanic Cloud (LMC), one of the satellite galaxies orbiting the Milky Way galaxy. This image spans about 230 light-years across.
Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those waves could be trapped in place. Writing today in Science a century later, a team of Columbia University researchers reports waves of electrons becoming trapped for the first time in a metal called Pd₅AlI₂.
Supermassive black holes ejected from galactic centers? Quasar survey supports decade-old predictionBy analyzing data on around 100,000 quasars, or extremely luminous galactic nuclei, researchers at Eötvös Loránd University (ELTE) have found statistical evidence that some supermassive black holes at the centers of galaxies are ejected from their positions after forming. The relationship now identified in the data was predicted 10 years ago by members of the same research group, Peter Raffai and Zsolt Frei, together with Zoltán Haiman.
Through past contact with the suspect, Glendale cops knew the man had animosity toward police; he called 911 during the standoff to say he was armed and refused to drop his weapons
The officer allegedly sent her brother a picture of a confidential bulletin informing officers to be on the lookout for a suspect who resembled him
An Aiken County Sheriff’s deputy was hospitalized after a suspect fleeing a traffic stop shot at him; a manhunt to locate the suspect is underway
Technion researchers have presented evidence for the existence of solar-storm-like outbursts near supermassive black holes, which can be a million times larger than the sun or more. The phenomenon was discovered in the vicinity of the black hole in the galaxy NGC 3783, and the researchers’ findings were published in The Astrophysical Journal Letters.
New research published in Scientific Reports finds that the sky in Vincent van Gogh’s “Starry Night” (1889) matches, in both observation and shape, the predawn sky over Saint-Rémy around July 22, 1889. In the early hours of that period, a waning crescent moon, Venus and the Hyades star cluster in Taurus appeared close together. The study was carried out jointly by SLLAB, a South Korean space-science company, and the School of Space Research at Kyung Hee University.
Scientific estimates show that there should be between about 100 million and 1 billion stellar-mass black holes in the Milky Way. But they aren’t easy to locate. They’re not like supermassive black holes (SMBH) at the centers of galaxies. Those are usually easy to spot for different reasons.
An international team of scientists from the University of Sheffield and the Indian Institute of Astrophysics, led by a postdoctoral research fellow from the University of Newcastle, Australia, has discovered that solar jets called spicules, which are 6–8 Mm long, take the form of warped, denser plasma sheets like pleated drapery.
Fort Worth Police Brian Gentry had been employed by the city as an officer since 2004; He was assigned to the fugitive unit as a U.S. Marshals Service task force officer
A new study suggests that some of the heaviest rocky planets ever reported may not be as heavy as they look. These so-called ‘mega-Earths,’ rocky planets weighing more than about 10 Earths, could be an illusion created by activity on their host stars. The paper was posted to the arXiv preprint server on Oct. 8.
Unlike classical physics, quantum mechanics generally cannot tell us exactly what will happen in an individual event. Instead, it predicts the probabilities of different outcomes. As one of the theory’s early pioneers, Erwin Schrödinger played a key role in debates about what this randomness really means. However, part of his contribution has stayed hidden for more than 80 years.
Semiconductors with wider bandgaps could pave the way for smaller, more efficient electronics that can handle far higher voltages, but the wider this gap becomes, the harder it is to control how well a material conducts electricity. Now, a team led by Darrell Schlom at Cornell University has shown that adding silicon to thin films of aluminum gallium oxide can keep this control intact at bandgaps wider than any semiconductor before it. Their research has been published in Nature.
Scientists from the Quantum Technologies Group at the Institute of Physics Zagreb, in collaboration with a colleague from the Physics Department at the Faculty of Science (PMF), have experimentally demonstrated for the first time the existence of discrete one-dimensional (1D) solitons in an optically induced photonic lattice in warm rubidium vapor.
