Published Giant planets cast a deadly pall
(via sciencedaily.com) Original source Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars. New studies show, in some planetary systems, the giants tend to kick smaller planets out of orbit and wreak havoc on their climates.
Published The Crab Nebula seen in new light by NASA's Webb
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 CE by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through thorough study of the Crab, a relatively nearby example.
Published Virtual meetings tire people because we're doing them wrong
(via sciencedaily.com) Original source New research suggests sleepiness during virtual meetings is caused by mental underload and boredom. Earlier studies suggested that fatigue from virtual meetings stems from mental overload, but new research shows that sleepiness during virtual meetings might actually be a result of mental underload and boredom.
Published Robot stand-in mimics movements in VR
(via sciencedaily.com) Original source Researchers have developed a souped-up telepresence robot that responds automatically and in real-time to a remote user's movements and gestures made in virtual reality.
Published Uranus aurora discovery offers clues to habitable icy worlds
(via sciencedaily.com) Original source Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
Published Venus had Earth-like plate tectonics billions of years ago, study suggests
(via sciencedaily.com) Original source Venus, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of early life on Venus, its evolutionary past and the history of the solar system.
Published Deep learning speeds up galactic calculations
(via sciencedaily.com) Original source Supernovae, exploding stars, play a critical role in the formation and evolution of galaxies. However, key aspects of them are notoriously difficult to simulate accurately in reasonably short amounts of time. For the first time, a team of researchers apply deep learning to the problem of supernova simulation. Their approach can speed up the simulation of supernovae, and therefore of galaxy formation and evolution as well. These simulations include the evolution of the chemistry which led to life.
Published Massive space explosion observed creating elements needed for life
(via sciencedaily.com) Original source Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Published First detection of heavy element from star merger
(via sciencedaily.com) Original source A team of scientists has used multiple space and ground-based telescopes to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion's aftermath.
Published Simulating cold sensation without actual cooling
(via sciencedaily.com) Original source The perception of persistent thermal sensations, such as changes in temperature, tends to gradually diminish in intensity as our bodies become accustomed to the temperature. This phenomenon leads to a shift in our perception of temperature when transitioning between different scenes in a virtual environment. Researchers have now developed a technology to generate a virtual cold sensation via a non-contact method without physically altering the skin temperature.
Published Black holes could come in 'perfect pairs' in an ever expanding Universe
(via sciencedaily.com) Original source Researchers have shown it's theoretically possible for black holes to exist in perfectly balanced pairs -- held in equilibrium by a cosmological force -- mimicking a single black hole.
Published Grasping the three-dimensional morphology of kilonovae
(via sciencedaily.com) Original source An advanced new three-dimensional (3D) computer simulation of the light emitted following a merger of two neutron stars has produced a similar sequence of spectroscopic features to an observed kilonova. '
Published Virtual reality helps people with hoarding disorder practice decluttering
(via sciencedaily.com) Original source A new study lets patients practice letting go of treasured objects in simulations of their own homes.
Published Virtual driving assessment predicts risk of crashing for newly licensed teen drivers
(via sciencedaily.com) Original source New research found that driving skills measured at the time of licensure on a virtual driving assessment (VDA), which exposes drivers to common serious crash scenarios, helps predict crash risk in newly licensed young drivers. This study brings the research community one step closer to identifying which skill deficits put young new drivers at higher risk for crashes. With this cutting-edge information, more personalized interventions can be developed to improve the driving skills that prevent crashes.
Published NASA's Webb captures an ethereal view of NGC 346
(via sciencedaily.com) Original source One of the greatest strengths of NASA's James Webb Space Telescope is its ability to give astronomers detailed views of areas where new stars are being born. The latest example, showcased here in a new image from Webb's Mid-Infrared Instrument (MIRI), is NGC 346 -- the brightest and largest star-forming region in the Small Magellanic Cloud.
Published Researchers capture first-ever afterglow of huge planetary collision in outer space
(via sciencedaily.com) Original source A chance social media post by an eagle-eyed amateur astronomer sparked the discovery of an explosive collision between two giant planets, which crashed into each other in a distant space system 1,800 light years away from planet Earth.
Published Finding explanation for Milky Way's warp
(via sciencedaily.com) Original source Though scientists have long known through observational data that the Milky Way is warped and its edges are flared like a skirt, no one could explain why. Now, astronomers have performed the first calculations that fully explain this phenomenon, with compelling evidence pointing to the Milky Way's envelopment in an off-kilter halo of dark matter.
Published Stellar fountain of youth with turbulent formation history in the center of our galaxy
(via sciencedaily.com) Original source An unexpectedly high number of young stars has been identified in the direct vicinity of a supermassive black hole and water ice has been detected at the center of our galaxy.
Published Astronomers discover first step toward planet formation
(via sciencedaily.com) Original source Astronomers have gotten very good at spotting the signs of planet formation around stars. But for a complete understanding of planet formation, we also need to study examples where planet formation has not yet started. Looking for something and not finding it can be even more difficult than finding it sometimes, but new detailed observations of the young star DG Taurus show that it has a smooth protoplanetary disk without signs of planet formation. This successful non-detection of planet formation may indicate that DG Taurus is on the eve of planet formation.
Published Pulsars may make dark matter glow
(via sciencedaily.com) Original source The central question in the ongoing hunt for dark matter is: what is it made of? One possible answer is that dark matter consists of particles known as axions. A team of astrophysicists has now shown that if dark matter consists of axions, it may reveal itself in the form of a subtle additional glow coming from pulsating stars.
