The last meteor shower of the year—the Ursids—peaks Sunday, a few days before Christmas. Go to Source MIT physicists have created a new and long-lasting magnetic state in a material, using only light. Go to Source More than a decade ago, dark matter experts Daniel Akerib and Thomas Shutt joined the Department of Energy’s SLAC National Accelerator Laboratory, continuing their mission to uncover the elusive substance. SLAC recently caught up with them to discuss the current state of the dark matter search. Go to Source A study of more than 26,000 white dwarf stars has confirmed a long-predicted but elusive effect in these ultra-dense, dying stars: Hotter white dwarfs are slightly puffier than cooler ones, even when they have the same mass. Go to Source An international research team has used the James Webb Space Telescope (JWST) to observe massive galaxies discovered by the Subaru Telescope in a corner of the early universe known as the Spiderweb protocluster. The JWST results confirm what had been suggested from the Subaru Telescope observations, namely that supermassive black hole activity can truncate the […] An international team of astronomers has analyzed multi-color photometric and spectroscopic observations of the star Gaia20bdk. As a result, they found that Gaia20bdk is a FUor-type young stellar object. The finding is presented in a paper published Dec. 10 on the arXiv preprint server. Go to Source In a span of less than 22 hours, SpaceX managed three Falcon 9 rocket launches and one landing of a Dragon spacecraft. Go to Source The woolly mammoth may have gone extinct as recently as 4,000 years ago on Wrangel Island near Alaska. However, scientists have been working diligently for years on bringing them back. In 2019, Japanese researchers made a breakthrough using 28,000-year-old DNA from Yuka, a perfectly preserved baby mammoth found on the Yukaghir coastline of Siberia […] Quantum computers have the potential of outperforming classical computers in some optimization and data processing tasks. However, quantum systems are also more sensitive to noise and thus prone to errors, due to the known physical challenges associated with reliably manipulating qubits, their underlying units of information. Go to Source Understanding and reliably measuring the geometric properties of quantum states can shed new light on the intricate underpinning of various physical phenomena. The quantum geometric tensor (QGT) is a mathematical object that provides a detailed description of how quantum states change in response to perturbations, thus offering insights about their underlying geometry. Go to Source […] Two US astronauts stranded for months on the International Space Station will remain there at least until late March, NASA said Tuesday as it announced another delay in the mission to bring them home. Go to Source Underneath a granite hill in southern China, a massive detector is nearly complete that will sniff out the mysterious ghost particles lurking around us. Go to Source Just as some children physically resemble their parents, many scientists have long thought that developing planets should resemble the swirling disk of gas and dust that births them. Go to Source A space rocket built by a Japanese startup blasted off on Wednesday but was later seen spiraling downwards in the distance as the company said the launch had to be terminated.
