Astronomers probe layer-cake structure of brown dwarf"s atmosphere
Brown dwarfs are the cosmic equivalent of tweeners. They're too massive to be planets and too small to sustain nuclear fusion in their cores, which powers stars. Many brown dwarfs are nomadic. They do not orbit stars but drift among them as loners......»»
Research investigates radio emission of the rotating radio transient RRAT J1854+0306
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have investigated radio emission from a rotating radio transient known as RRAT J1854+0306. Results of the study, published April 15 on the preprint server arX.....»»
Researchers establish a high-throughput multiscale evaluation method for thermal stress in thermal barrier coatings
Thermal barrier coatings (TBCs) are widely used in gas turbine engines to obtain elevated working temperatures and improve engine efficiency. The phase transition of the ceramic layer is accompanied by a large volume difference, causing the concentra.....»»
TESS finds its first rogue planet
Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising discovery; their first free.....»»
Recently discovered black hole is part of a nearby disrupted star cluster, study finds
European astronomers have investigated a recently detected black hole designated Gaia BH3. In their results, they found that the black hole is associated with a nearby disrupted star cluster known as ED-2. The finding is reported in a paper published.....»»
Artificial intelligence helps scientists engineer plants to fight climate change
The Intergovernmental Panel on Climate Change (IPCC) has declared that removing carbon from the atmosphere is now essential to fighting climate change and limiting global temperature rise. To support these efforts, Salk Institute scientists are harne.....»»
How NASA Repaired Voyager 1 From 15 Billion Miles Away
The far-traveled space probe is once again transmitting usable data, after a glitch caused months of gibberish......»»
Scientists tune the entanglement structure in an array of qubits
Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain the macroscopic behavior.....»»
Black hole "traffic jams" discovered in galactic centers by astronomers
An international study, led by researchers from Monash University, has revealed crucial insights into black hole dynamics within massive disks at the centers of galaxies......»»
Airborne observations of Asian monsoon sees ozone-depleting substances lofting into the stratosphere
Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, new research shows......»»
Star bars show universe"s early galaxies evolved much faster than previously thought
The universe's early galaxies were less chaotic and developed much faster than previously thought, according to new research looking back more than ten billion years in time. An international team of astronomers led by Durham University, UK, has used.....»»
A new electrochemical approach could reduce ocean acidity and remove carbon in the process
In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The technologies for reducing ou.....»»
From the coast to the deep sea, changing oxygen levels affect marine life in different ways
Earth's atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time. Sometimes oxygen levels change within the course.....»»
Manipulating the geometry of the "electron universe" in magnets
Researchers at Tohoku University and the Japan Atomic Energy Agency have developed fundamental experiments and theories to manipulate the geometry of the "electron universe," which describes the structure of electronic quantum states in a manner math.....»»
Observations explore globular cluster system in the galaxy NGC 4262
Using the Canada-France-Hawaii Telescope (CFHT), Indian astronomers have performed wide and deep field observations of a polar ring galaxy known as NGC 4262. Results of the observational campaign, published April 15 on the pre-print server arXiv, she.....»»
Researchers report on mechanisms of gene regulatory divergence between species
Closely related animal species can look physically different, but you might be surprised to learn that those differences can result not only from DNA sequence changes that alter proteins' structure or function, but also because changes in the DNA aff.....»»
AI and physics combine to reveal the 3D structure of a flare erupting around a black hole
Scientists believe the environment immediately surrounding a black hole is tumultuous, featuring hot magnetized gas that spirals in a disk at tremendous speeds and temperatures. Astronomical observations show that within such a disk, mysterious flare.....»»
Astronomers offer new model for formation of recently discovered "free-floating" planets
The recent discovery of a potential new class of distant and mysterious "free-floating" planets has intrigued astronomers since stunning new images captured by the James Webb Space Telescope were shared late last year......»»
Pulsating Snake: First millisecond pulsar discovered in the galactic center
Astronomers from the Australia Telescope National Facility (ATNF) report the discovery of a new millisecond pulsar in the "Snake"—a radio filament in the galactic center. It is the first millisecond pulsar detected in the center of our galaxy. The.....»»
Astronomers discover largest stellar black hole in Milky Way: Study
Astronomers identified the largest stellar black hole yet discovered in the Milky Way, with a mass 33 times that of the Sun, according to a study published on Tuesday......»»
