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.
In 2024, a U.S. government official warned that Russia could be developing a new satellite designed to carry nuclear weapons into space. The statement followed the launch of a suspicious Russian satellite into low-Earth orbit in 2022, just a few weeks before the country’s full-scale invasion of Ukraine.
Quantum computers, devices that store and process information leveraging the principles of quantum mechanics, have been found to be promising for tackling some problems that cannot be solved by classical computers. Quantum computers store data in the form of qubits (i.e., quantum bits), units of information that can exist in combinations of different states, instead of being limited to a binary value (i.e., 0 or 1), like classical bits.
The teen suspects are accused of shooting water bead guns and drinking while riding in the autonomous vehicle; the Waymo contacted San Mateo Police and waited in a parking lot until they arrived
When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe. The event is so energetic that it significantly distorts the universe around it. It emits gravitational waves—ripples in the fabric of spacetime—that are strong enough to be detected with precision instruments on Earth even when they originate billions of light-years away.
Hayabusa 2’s primary mission is now well in the past. JAXA’s asteroid-sampling spacecraft rendezvoused with asteroid Ryugu in June 2018. It studied the asteroid for 1.5 years and gathered a sample that was returned to Earth in December 2020.
Astronomers studying a population of unusually X-ray-silent and overmassive black holes discovered by the James Webb Space Telescope have found that they may not be as massive as they appear. The new paper, outlining a plausible scenario that would produce such black holes, was published in Astronomy & Astrophysics on June 19.
