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......»»
James Webb observes extremely hot exoplanet with 5,000 mph winds
Astronomers using the James Webb telescope have modeled the weather on a distant exoplanet, revealing winds whipping around at speeds of 5,000 miles per hour......»»
X-ray satellite XMM-Newton sees "space clover" in a new light
Astronomers have discovered enormous circular radio features of unknown origin around some galaxies. Now, new observations of one dubbed the Cloverleaf suggest it was created by clashing groups of galaxies......»»
Weak magnetic field may have supported diversification of life on Earth
An unusual reduction in the strength of Earth's magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere and oceans, according to a paper published in Communications Earth & Env.....»»
Researchers detect toxic chemicals in aquatic organisms with new AI method
Swedish researchers at Chalmers University of Technology and the University of Gothenburg have developed an AI method that improves the identification of toxic chemicals—based solely on knowledge of the molecular structure......»»
TOI-837 b is a young Saturn-sized exoplanet with a massive core, observations find
European astronomers have performed photometric and spectroscopic observations of a distant giant exoplanet known as TOI-837 b. As a result, they found that TOI-837 b is a young Saturn-sized planet containing a massive core, which challenges current.....»»

New computer algorithm supercharges climate models and could lead to better predictions of future climate change
Earth System Models—complex computer models that describe Earth processes and how they interact—are critical for predicting future climate change. By simulating the response of our land, oceans and atmosphere to manmade greenhouse gas emissions,.....»»
Porsche study concludes aluminum could reduce Taycan weight, increase manufacturing simplicity
The study by Alumobility found switching the electric Taycan's top hat structure to all-aluminum could cut down on weight by about 40 percent......»»
An AI model to reduce uncertainty in evapotranspiration prediction
When scientists look at the Earth's available water for ecosystem services, they don't just look at precipitation. They must also account for water moving from the ground to the atmosphere, a process known as evapotranspiration (ET)......»»
Researchers explore an old galactic open cluster
Using data from ESA's Gaia satellite, astronomers from Turkey and India have investigated NGC 188—an old open cluster in the Milky Way. Results of the study, published April 19 on the pre-print server arXiv, deliver important insights into the para.....»»
Astronomers" simulations support dark matter theory
Computer simulations by astronomers support the idea that dark matter—matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe—exists, according to the resear.....»»
Study is first to describe and recreate lemurs" one-of-a-kind vocal structure
New research has discovered that lemurs, the small primates native to Madagascar, are capable of exaggerating their size thanks to the unique structure of their larynx......»»
Neutron stars could be capturing primordial black holes
The Milky Way has a missing pulsar problem in its core. Astronomers have tried to explain this for years. One of the more interesting ideas comes from a team of astronomers in Europe and invokes dark matter, neutron stars, and primordial black holes.....»»
Q&A: How to catch a glimpse of a new star about to appear in the night sky
If you peer up at the constellation Corona Borealis—the Northern Crown—over the next several months, you may catch a glimpse: Astronomers predict that sometime this year, a new star will appear in the night sky, growing as bright as the North Sta.....»»
Pump-probe high-harmonic spectroscopy could catch geometric phase effect around conical intersection in molecule: Study
A collaborative research team from Nanjing University of Science and Technology (NJUST) and East China Normal University (ECNU) has theoretically proposed that a pump-probe high-harmonic spectroscopy (HHS) driven by VUV-IR pulses can catch the geomet.....»»
Meta to face EU probe for not doing enough to stop Russian disinformation
Insufficient moderation of political ads risk undermining electoral process. Enlarge (credit: FT) Brussels is set to open a probe into Meta’s Facebook and Instagram as soon as Monday over concerns the social media gian.....»»
Mercedes-Benz says U.S. ended diesel probe without filing charges
The decision is “another important step towards legal certainty in connection with various diesel proceedings,” said Renata Jungo Bruengger, a member of the Mercedes-Benz management board......»»
Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
Orion"s erupting star system reveals its secrets
An unusual group of stars in the Orion constellation have revealed their secrets. FU Orionis, a double star system, first caught astronomers' attention in 1936 when the central star suddenly became 1,000 times brighter than usual. This behavior, expe.....»»
