Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way galaxy. However, most of them are effectively invisible. A new study published in Astronomy & Astrophysics suggests that NASA’s upcoming Nancy Grace Roman Space Telescope could spot them anyway. Go to Source […] Supermassive black holes lurk at the centers of massive galaxies, including our own Milky Way. Puzzlingly, supermassive black holes more than a billion times the mass of the sun appear to exist just a few hundred million years after the Big Bang, when the universe was less than 5% of its current age. As interstellar […] Superconductors are materials that can conduct electricity with a resistance of zero. In so-called conventional superconductors, this occurs at low temperatures when electrons become bound into pairs, known as Cooper pairs. Go to Source An international team led by researchers at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) has developed a new method that could significantly improve our understanding of the expansion of the universe and the nature of dark energy. Go to Source In-situ Resource Utilization (ISRU) is our best bet for “living off the land” for a future Martian base, but tracking down those resources is no easy task. As of now, we have two options—send a rover to a specific location to scout it, or monitor it from orbit. Since rovers are expensive, and there are […] Quantum geometry describes quantum states in systems with changing system parameters, such as an electron spinning in a magnetic field whose direction is slowly changing. The state of the electron evolves, and this change is quantified by what is known as the quantum geometric distance. Go to Source Astronomers from the South African Astronomical Observatory (SAAO) and elsewhere have conducted photometric and spectroscopic observations of a cataclysmic variable system designated SRGA J115215.0−510656. Results of the new observations, published April 29 on the arXiv pre-print server, indicate that the investigated system is an unusual long-period dwarf nova. Go to Source Four humans recently looped around the moon. Their vessel, an Artemis capsule, was a thin metal shell whose life-support system kept them alive: it provided a carefully balanced atmosphere, a closed water loop, a finite supply of food, and a means for disposing of human waste. The life support was not optional. It was a […] Astronomers using the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope have looked deeply at thousands of young star clusters in four nearby galaxies, studying clusters at different stages of evolution. Their findings show that more massive star clusters emerge more quickly from the clouds they are born in, clearing away […] The trooper was responding to reports of a wrong-way driver on Route 1 when the suspect vehicle struck his cruiser head-on Go to Source Surveillance and body camera video show the Oak Creek officer being forced onto the hood of his squad car as the suspect rapidly reversed from the scene Go to Source A new type of hologram technology has been developed that uses the motion of light as a key, revealing information only under specific conditions. This is gaining attention as a novel approach that can simultaneously overcome the limitations of existing optical communication and security technologies. Go to Source The administrative leave follows separate congressional and federal investigations into claims that D.C. crime reports were misclassified to lower reported crime rates Go to Source Officers made two calls for an ambulance before transporting the 22-year-old themselves during a medical emergency Go to Source Scientists have discovered the cause of a persistent glitch that continues to disrupt superconducting quantum computers, even when they have built-in defenses. For all their advanced hardware, superconducting quantum computers are vulnerable to errors caused by ionizing radiation from space or the environment. Radiation particles interfere with the chip substrate (the silicon base the processor […] |
