Brown dwarfs get a bad rap in the stellar world, often labeled as “failed stars” for their inability to sustain nuclear fusion at their cores. The mass of these objects falls between planets and stars, ranging from 13 to 80 times the mass of Jupiter. Because they aren’t massive enough to sustain fusion, they are […] Researchers at the Department of Energy’s SLAC National Accelerator Laboratory and collaborating institutions recently built a generative AI model that can recreate molecular structures from the movement of the molecule’s ions after they are blasted apart by X-rays, a technique called Coulomb explosion imaging. Go to Source In a happy twist of fate, NASA’s Hubble Space Telescope witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings are published in the journal Icarus. Go to Source Quantum computers could solve certain problems that would take traditional classical computers an impractically long time to solve. At the Japan Advanced Institute of Science and Technology (JAIST), researchers are now working to make these systems reliable and trustworthy. Go to Source The Earth is under assault. Space rocks are constantly hurtling toward us, slamming into the atmosphere and often exploding into fireballs that both delight and alarm. Go to Source The man, who was on inmate release status at the time of the incident, wove through traffic and fled at high speeds before ultimately surrendering to Flagler County officers Go to Source How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter timescales. In a study published in the Physical Review Letters and highlighted in the Physics magazine, scientists propose an explanation that resolves this contradiction. They say that […] Greek mythology has given a name to a great many objects in our solar system. But perhaps one of the least well understood are the Trojans, named after the people of Troy featured in “The Iliad.” When astronomers refer to them, they are normally talking about a group of more than 10,000 confirmed asteroids orbiting […] The suspect shot and wounded South Daytona Police Officer Jake Fessenden before climbing into his cruiser; the cruiser then caught fire with the suspect inside Go to Source Two microscopic grains collide and produce a tiny spark. This phenomenon may have provided the energy to kick off life on Earth. But if these solid particles have the same composition, what factor causes the charge to flow in a given direction? In a study published in Nature, physicists from the Institute of Science and […] Cancer the Crab is a dim constellation, yet it contains one of the most beautiful and easy-to-spot star clusters in our sky: the Beehive Cluster. Cancer also possesses one of the most studied exoplanets: the superhot super-Earth, 55 Cancri e. Go to Source Two recent studies suggest that fiber-optic cables laid directly on the moon’s surface could potentially detect moonquakes, offering a simpler way to gather seismic data to support future human and robotic exploration. Go to Source You’re late for an important appointment. Just as you are leaving your house, you realize your phone is flat. Imagine you could charge it almost instantly by exploiting the strange rules of quantum physics. That’s the promise of quantum batteries. Go to Source For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive than planets but too small to ignite nuclear fusion like true stars. Through a telescope, these cosmic lookalikes can have overlapping brightness, temperatures, and even atmospheric fingerprints. The striking similarity leaves astronomers unsure if they have observed […] Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that arises without any mechanical contact, driven purely by collective magnetic dynamics. The study, published in Nature Materials, shows that friction does not necessarily increase steadily with load, as postulated by Amontons’ law—one of the oldest and most […] |
