Published Persistent hiccups in a far-off galaxy draw astronomers to new black hole behavior
(via sciencedaily.com) Original source Astronomers have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state.
Published Robot, can you say 'cheese'?
(via sciencedaily.com) Original source What would you do if you walked up to a robot with a human-like head and it smiled at you first? You'd likely smile back and perhaps feel the two of you were genuinely interacting. But how does a robot know how to do this? Or a better question, how does it know to get you to smile back?
Published Astronomers unveil strong magnetic fields spiraling at the edge of Milky Way's central black hole
(via sciencedaily.com) Original source A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes.
Published Distant 'space snowman' unlocks mystery of how some dormant deep space objects become 'ice bombs'
(via sciencedaily.com) Original source Researchers found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ices stored deep within it from when the object first formed billions of years ago.
Published Turbulence within solar transients imaged
(via sciencedaily.com) Original source Scientists captured images showing the development of turbulence as a Coronal Mass Ejection (CME) interacted with the ambient solar wind in the circumsolar space.
Published 'Cosmic cannibals' expel jets into space at 40 percent the speed of light
(via sciencedaily.com) Original source Astronomers have measured the speed of fast-moving jets in space, crucial to star formation and the distribution of elements needed for life. The jets of matter, expelled by stars deemed 'cosmic cannibals', were measured to travel at over one-third of the speed of light -- thanks to a groundbreaking new experiment.
Published Sleeping supermassive black holes awakened briefly by shredded stars
(via sciencedaily.com) Original source Astronomers have concluded that an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, are not young as previously thought but rather lead relatively short lives.
Published Tiniest 'starquake' ever detected
(via sciencedaily.com) Original source An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
Published Scientists on the hunt for evidence of quantum gravity's existence at the South Pole
(via sciencedaily.com) Original source An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.
Published Engineering household robots to have a little common sense
(via sciencedaily.com) Original source Engineers aim to give robots a bit of common sense when faced with situations that push them off their trained path, so they can self-correct after missteps and carry on with their chores. The team's method connects robot motion data with the common sense knowledge of large language models, or LLMs.
Published Astronomers discover 49 new galaxies in under three hours
(via sciencedaily.com) Original source New work aimed to study the star-forming gas in a single radio galaxy. Although the team didn't find any star-forming gas in the galaxy they were studying, they instead discovered other galaxies while inspecting the data. In total, the gas of 49 galaxies was detected.
Published James Webb Space Telescope captures the end of planet formation
(via sciencedaily.com) Original source How much time do planets have to form from a swirling disk of gas and dust around a star? A new study gives scientists a better idea of how our own solar system came to be.
Published Signs of life would be detectable in single ice grain emitted from extraterrestrial moons
(via sciencedaily.com) Original source Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.
Published Two of the Milky Way's earliest building blocks identified
(via sciencedaily.com) Original source Astronomers have identified what could be two of the Milky Way's earliest building blocks: Named 'Shakti' and 'Shiva', these appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy's initial growth. The new find is the astronomical equivalent of archeologists identifying traces of an initial settlement that grew into a large present-day city.
Published Secrets of the Van Allen belt revealed in new study
(via sciencedaily.com) Original source A challenge to space scientists to better understand our hazardous near-Earth space environment has been set in a new study.
Published High school students contribute to exoplanet discovery
(via sciencedaily.com) Original source A group of high school students from Oakland, California, made contributions to the field of exoplanet research. Researchers worked with the students to use backpack-sized digital smart telescopes. These young citizen scientists played a role in observing and confirming the nature of a warm and dense sub-Saturn planet, known as TIC 139270665 b, orbiting a metal-rich G2 star.
Published Universal controller could push robotic prostheses, exoskeletons into real-world use
(via sciencedaily.com) Original source A team of researchers has developed a universal approach to controlling robotic exoskeletons that requires no training, no calibration, and no adjustments to complicated algorithms. Instead, users can don the 'exo' and go. Their system uses a kind of artificial intelligence called deep learning to autonomously adjust how the exoskeleton provides assistance, and they've shown it works seamlessly to support walking, standing, and climbing stairs or ramps.
Published Icy impacts: Planetary scientists use physics and images of impact craters to gauge the thickness of ice on Europa
(via sciencedaily.com) Original source New study reveals that Europa's ice shell is at least 20 kilometers thick.
Published Scientists find one of the most ancient stars that formed in another galaxy
(via sciencedaily.com) Original source The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.
Published Robotic metamaterial: An endless domino effect
(via sciencedaily.com) Original source If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.
