Imagine if we could take the energy of the sun, put it in a container, and use it to provide green, sustainable power for the world. Creating commercial fusion power plants would essentially make this idea a reality. However, there are several scientific challenges to overcome before we can successfully harness fusion power in this way.
How do you find and measure nuclear particles, like antineutrinos, that travel near the speed of light?
NASA researchers have discovered a perplexing case of a black hole that appears to be “tipped over,” rotating in an unexpected direction relative to the galaxy surrounding it. That galaxy, called NGC 5084, has been known for years, but the sideways secret of its central black hole lay hidden in old data archives. The discovery was made possible by new image analysis techniques developed at NASA’s Ames Research Center in California’s Silicon Valley that allowed researchers to take a fresh look at archival data from the agency’s Chandra X-ray Observatory.
A team of researchers has identified a unique phenomenon, a “skin effect,” in the nonlinear optical responses of antiferromagnetic materials. The research, published in Physical Review Letters, provides new insights into the properties of these materials and their potential applications in advanced technologies.
A new article published in Universe describes an approach that looks back from the deaths of stars to their births, allowing the so-called initial mass function (IMF), i.e. the way in which star masses are distributed after their formation, to be derived from observations of supernovae and gamma radiation.
An international team of astronomers, led by researchers from the Astronomical Observatory of the University of Warsaw, have identified a new class of cosmic X-ray sources. The findings have been published in The Astrophysical Journal Letters.
Although our solar system is billions of years old, we’ve only recently become better acquainted with one of its more dynamic and captivating inhabitants known as (2060) Chiron.
Quiet quitting isn’t just for burned out employees. Atoms carrying information inside quantum computers, known as qubits, sometimes vanish silently from their posts. This problematic phenomenon, called atom loss, corrupts data and spoils calculations.
“[This] was the best-case scenario. Unfortunately, yes, [Officer Michael Cook] was struck in the leg, but he got to go home to his family,” Muskogee Police stated
It seems that we are completely alone in the universe. But simple reasoning suggests that there should be an abundance of alien civilizations. Maybe they’re all out there, but they are keeping their distance. Welcome to the zoo (hypothesis).
In the quest for ultra-precise timekeeping, scientists have turned to nuclear clocks. Unlike optical atomic clocks—which rely on electronic transitions—nuclear clocks utilize the energy transitions in the atom’s nucleus, which are less affected by outside forces, meaning this type of clock could potentially keep time more accurately than any previously existing technology.
When Waterbury Police officers instructed the man to get out of the car, he instead put it in drive and began moving forward, partially pinning an officer between the car and a cruiser
Scientists have spotted a massive black hole in the early universe that is “napping” after stuffing itself with too much food. Like a bear gorging itself on salmon before hibernating for the winter, or a much-needed nap after Christmas dinner, this black hole has overeaten to the point that it is lying dormant in its host galaxy.
The last meteor shower of the year—the Ursids—peaks Sunday, a few days before Christmas.
MIT physicists have created a new and long-lasting magnetic state in a material, using only light.
