Published Webb Telescope offers first glimpse of an exoplanet's interior
(via sciencedaily.com) Original source A surprisingly low amount of methane and a super-sized core hide within the cotton candy -- like planet WASP-107 b.
Published Building a better sarcasm detector
(via sciencedaily.com) Original source Sarcasm is notoriously tricky to convey through text, and the subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools. So researchers have now developed a multimodal algorithm for improved sarcasm detection that examines multiple aspects of audio recordings for increased accuracy. They used two complementary approaches -- sentiment analysis using text and emotion recognition using audio -- for a more complete picture.
Published Hubble views the dawn of a sun-like star
(via sciencedaily.com) Original source Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.
Published Detection of an Earth-sized exoplanet orbiting the ultracool dwarf star SPECULOOS-3
(via sciencedaily.com) Original source Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second planetary system discovered around this type of star.
Published Virtual reality becomes more engaging when designers use cinematic tools
(via sciencedaily.com) Original source Cinematography techniques can significantly increase user engagement with virtual environments and, in particular, the aesthetic appeal of what users see in virtual reality.
Published WASP-193b, a giant planet with a density similar to that of cotton candy
(via sciencedaily.com) Original source Astronomers have just discovered WASP-193b, an extraordinarily low-density giant planet orbiting a distant Sun-like star.
Published Researchers discover the universe's oldest stars in our own galactic backyard
(via sciencedaily.com) Original source Astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way's 'halo' -- the cloud of stars that envelopes the entire main galactic disk -- and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape.
Published Squeezed by neighbors, planet glows with molten lava
(via sciencedaily.com) Original source Astrophysicists discovered that an exoplanet is covered with so many active volcanoes that seen from a distance it would take on a fiery, glowing-red hue.
Published Astrophysicists discover a novel method for hunting the first stars
(via sciencedaily.com) Original source A recent study has discovered a novel method for detecting the first-generations stars, known as Population III (Pop III) stars, which have never been directly detected. These potential discoveries about Pop III stars hold the promise of unlocking the secrets of the universe's origin and providing a deeper understanding of the remarkable journey from the primordial cosmos to the world we inhabit today.
Published Possible atmosphere surrounding rocky exoplanet
(via sciencedaily.com) Original source Researchers may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.
Published Iron fingerprints in nearby active galaxy
(via sciencedaily.com) Original source After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC 4151.
Published Venus has almost no water: A new study may reveal why
(via sciencedaily.com) Original source Billions of years ago, Venus may have harbored as much water as Earth. Today, almost all of it has disappeared. A new study may help to explain why.
Published VR may pose privacy risks for kids: A new study finds parents aren't as worried as they should be
(via sciencedaily.com) Original source New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using parental controls built into the apps.
Published Astronomers observe elusive stellar light surrounding ancient quasars
(via sciencedaily.com) Original source Astronomers observed the elusive starlight surrounding some of the earliest quasars in the universe. The findings may shed light on how the earliest supermassive black holes became so massive despite having a relatively short amount of cosmic time in which to grow.
Published Hubble views a galaxy with a voracious black hole
(via sciencedaily.com) Original source Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).
Published New discoveries about Jupiter's magnetosphere
(via sciencedaily.com) Original source New discoveries about Jupiter could lead to a better understanding of Earth's own space environment and influence a long-running scientific debate about the solar system's largest planet.
Published Biomechanical dataset for badminton performance analysis
(via sciencedaily.com) Original source In the sports industry, player data collection aids in personalized training feedback. Researchers have now gathered a detailed dataset and laid the foundation for delivering coaching assistance and feedback through the same. Utilizing wearable sensors and machine learning, their dataset offers real-time feedback and optimized movement suggestions. With over 7,763 badminton swings analyzed, stroke quality assessment offers valuable insights, making badminton training more accessible and affordable.
Published Unveiling a polarized world -- in a single shot
(via sciencedaily.com) Original source Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock the vast potential of polarization imaging for a range of existing and new applications, including biomedical imaging, augmented and virtual reality systems and smart phones.
Published Webb telescope probably didn't find life on an exoplanet -- yet
(via sciencedaily.com) Original source Recent reports of NASA's James Webb Space Telescope finding signs of life on a distant planet understandably sparked excitement. A new study challenges this finding, but also outlines how the telescope might verify the presence of the life-produced gas.
