Published Peering into the tendrils of NGC 604 with NASA's Webb
(via sciencedaily.com) Original source The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA's James Webb Space Telescope.
Published Nasa’s Webb, Hubble telescopes affirm universe’s expansion rate, puzzle persists
(via sciencedaily.com) Original source When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the 'Hubble Tension,' is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe's evolution.
Published Balancing training data and human knowledge makes AI act more like a scientist
(via sciencedaily.com) Original source When you teach a child how to solve puzzles, you can either let them figure it out through trial and error, or you can guide them with some basic rules and tips. Similarly, incorporating rules and tips into AI training -- such as the laws of physics --could make them more efficient and more reflective of the real world. However, helping the AI assess the value of different rules can be a tricky task.
Published CSI in space: Analyzing bloodstain patterns in microgravity
(via sciencedaily.com) Original source As more people seek to go where no man has gone before, researchers are exploring how forensic science can be adapted to extraterrestrial environments. A new study highlights the behavior of blood in microgravity and the unique challenges of bloodstain pattern analysis aboard spacecraft.
Published Interstellar signal linked to aliens was actually just a truck
(via sciencedaily.com) Original source Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
Published Method rapidly verifies that a robot will avoid collisions
(via sciencedaily.com) Original source A new safety-check technique can prove with 100 percent accuracy that a planned robot motion will not result in a collision. The method can generate a proof in seconds and does so in a way that can be easily verified by a human.
Published Drawings of mathematical problems predict their resolution
(via sciencedaily.com) Original source Solving arithmetic problems, even simple subtractions, involves mental representations whose influence remains to be clarified. Visualizing these representations would enable us to better understand our reasoning and adapt our teaching methods. A team has now analyzed drawings made by children and adults when solving simple problems. The scientists found that, whatever the age of the participant, the most effective calculation strategies were associated with certain drawing typologies. These results open up new perspectives for the teaching of mathematics.
Published Baby quasars: Growing supermassive black holes
(via sciencedaily.com) Original source The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.
Published Finding new physics in debris from colliding neutron stars
(via sciencedaily.com) Original source Neutron star mergers are a treasure trove for new physics signals, with implications for determining the true nature of dark matter, according to physicists.
Published Astronomers spot oldest 'dead' galaxy yet observed
(via sciencedaily.com) Original source A galaxy that suddenly stopped forming new stars more than 13 billion years ago has been observed by astronomers. Using the James Webb Space Telescope, astronomers have spotted a 'dead' galaxy when the universe was just 700 million years old, the oldest such galaxy ever observed.
Published Space tourism? Cosmic radiation exposure
(via sciencedaily.com) Original source Space weather experts are urging regulators and space tourism innovators to work together to protect their passengers and crews from the risks of space weather radiation exposure.
Published Running performance helped by mathematical research
(via sciencedaily.com) Original source A new mathematical model has shown, with great precision, the impact that physiological and psychological parameters have on running performance and provides tips for optimized training.
Published Groundbreaking survey reveals secrets of planet birth around dozens of stars
(via sciencedaily.com) Original source A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.
Published JWST captures the end of planet formation
(via sciencedaily.com) Original source The James Webb Space Telescope is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars. Scientists have imaged winds from an old planet-forming disk (still very young relative to the Sun) which is actively dispersing its gas content. Knowing when the gas disperses is important as it constrains the time left for nascent planets to consume the gas from their surroundings.
Published Webb unlocks secrets of one of the most distant galaxies ever seen
(via sciencedaily.com) Original source Looking deeply into space and time, astronomers have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old.
Published Study determines the original orientations of rocks drilled on Mars
(via sciencedaily.com) Original source Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.
Published Ultraviolet radiation from massive stars shapes planetary systems
(via sciencedaily.com) Original source Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.
Published Ice shell thickness reveals water temperature on ocean worlds
(via sciencedaily.com) Original source Astrobiologists have devised a novel way to determine ocean temperatures of distant worlds based on the thickness of their ice shells, effectively conducting oceanography from space.
Published Could fiber optic cable help scientists probe the deep layers of the moon?
(via sciencedaily.com) Original source An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth -- but how would this technology fare on the Moon, and what would it tell us about the deep layers of our nearest neighbor in space?
Published Astronomers reveal a new link between water and planet formation
(via sciencedaily.com) Original source Researchers have found water vapor in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in planet formation. Yet, until now, we had never been able to map how water is distributed in a stable, cool disc -- the type of disc that offers the most favorable conditions for planets to form around stars.
