A new Southwest Research Institute-led study proposes a solution to a longstanding puzzle in planetary science: What caused the concentration, assembly, and preservation of millimeter-sized, spherical mineral grains within the parent bodies of the most common meteorites? The work is published in the journal Science Advances.
If a liquid is cooled slowly to its freezing point, it becomes a crystal in which the constituent particles are arranged in an ordered pattern. In contrast, when the liquid is cooled very quickly, the particles are unable to arrange themselves in an ordered fashion, and it becomes glass. Glassy materials are all around us in everyday life. Common examples include window glass, certain metal alloys, polymers, foams, gels and even soft materials like emulsions and colloids.
The Portland Police officers were able to place the suspect into custody before going to a hospital with non-life-threatening injuries
Scientists from Queen’s University Belfast have led an international team in the discovery of a rare new planet, which is larger than Jupiter and orbits a distant star every 180 days. Named NGTS-38 b, it is an exoplanet—a planet that orbits a star beyond our solar system. It is about 8% larger than Jupiter and almost five times more massive. Planets of this size and mass are often referred to as “super-Jupiters.”
In a new study, published in the Journal of the Astronautical Sciences, Warwick researchers led an international effort to uncover some of the faintest debris in geosynchronous orbit ever observed, finding fragments as small as 5 centimeters (2 inches) and obtaining valuable data to characterize their behavior.
Plasma pinches: From pursuits of nuclear fusion to an attractive point source of accelerated protons for proton radiography.
This image from NASA’s Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way’s most massive globular clusters, or spherical collections of gravitationally bound stars.
Astronomers spend much of their time mapping the universe, but until now their results have been collected and archived in so many different ways that the data can’t talk to each other.
Researchers are closer to unraveling a longstanding solar mystery surrounding the extreme thinness of the sun’s tachocline layer of strong shearing motion—a region believed to be critical for creating the violent eruptions of high-energy particles and radiation from the sun known as “space weather.”
The St. Peter Police officer was at the front of a line of officers climbing a set of stairs when a shotgun-wielding suspect fired at them, striking the officer in the arm and vest
Building material samples from the University of Delaware spent six months mounted outside the International Space Station, where the harsh conditions of low Earth orbit tested their limits.
A former Barrackville sergeant says he and the department’s remaining officer were placed on inactive status after reporting that the evidence room had been broken into
Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have detected an extraordinary burst of radio light from a rare cosmic event in which an intermediate-mass black hole tears apart a star, revealing what appears to be the off-axis afterglow of a powerful jet. The research is published in The Astrophysical Journal Letters.
The explosive growth of data generated by artificial intelligence, cloud computing and modern digital infrastructure is placing increasing pressure on existing information storage technologies. Although magnetic storage systems such as hard disk drives remain the dominant platform for digital storage, they face challenges including rising costs, limited lifespan and relatively slow information retrieval.
