Astronomers have recently found hundreds of “polluted” white dwarf stars in our home galaxy, the Milky Way. These are white dwarfs caught actively consuming planets in their orbit. They are a valuable resource for studying the interiors of these distant, demolished planets. They are also difficult to find. Go to Source Bigger antennas are better, at least according to researchers interested in geospatial monitoring. That’s because higher resolution in monitoring applications requires larger apertures. So imagine the excitement in the remote sensing community when a researcher from Leidos, a government consulting firm, developed an idea that dramatically increased the effective aperture size of a remote radio-frequency […] An international team of astronomers and astrophysicists studying data and imagery received from the James Webb Space Telescope (JWST) has found that light emitted from one of the earliest galaxies identified thus far, is due to continuing bursts from star formations. Go to Source The stars aren’t fixed and unchanging, unlike what many ancient people thought. Once in a while, a star appears where there wasn’t one before, and then it fades away in a matter of days or weeks. Go to Source Interest in interstellar objects (ISOs) was ignited in 2017 when ‘Oumuamua flew through our solar system and made a flyby of Earth. Roughly two years later, another ISO passed through our solar system—the interstellar comet 2I/Borisov. Go to Source MIT physicists and colleagues report new insights into exotic particles key to a form of magnetism that has attracted growing interest because it originates from ultrathin materials only a few atomic layers thick. The work, which could impact future electronics and more, also establishes a new way to study these particles through a powerful instrument […] An international team of scientists, led by Trinity College Dublin, has devised an innovative imaging method using state-of-the-art microscopes that significantly reduces the time and radiation required. Their work represents a significant breakthrough that will benefit several disciplines, from materials science to medicine, as the method promises to deliver improved imaging for sensitive materials such […] There has been plenty of rain, sweat and tears shed at the Paris Olympics this week. But the pool at the heart of La Defénce Arena has suffered a drought of world records that has athletes and officials scratching their heads. Go to Source Quantum technology is quantifiable in qubits, which are the most basic unit of data in quantum computers. The operation of qubits is affected by the quantum coherence time required to maintain a quantum wave state. Go to Source Room-temperature superconductivity has been a century-long-held dream of scientists. Hydrogen-rich compounds at high pressures are predicted to be potential high-temperature and even room-temperature superconductors and have become one of the superconducting materials that have received much attention in recent years. Go to Source When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (LIGO) telescope in September 2015. Go to Source The Oct. 24, 2022 shooting resulted in the deaths of two people; the video footage shows security guards and PD officers working together to neutralize the threat Go to Source Donna Massey described her daughter’s mental health symptoms and was afraid an officer would harm her Go to Source Anchorage Police Department officers used a loudspeaker to instruct the man to come out with his hands up; instead, he immediately moved toward officers with the gun Go to Source |
