A project led by the University of Melbourne’s Dr. Manjith Bose and Professor Jeff McCallum, who are also members of the ARC Center of Excellence for Quantum Computation and Communication Technology, has identified a promising class of superconductors that may potentially avoid the need for high levels of cryogenic cooling. These advanced materials can be […] An international team of astronomers reports the discovery of a new ultracompact binary of the AM CVn type exhibiting infrequent outbursts. The detection of the newfound system, designated TCP J07222683+6220548, was detailed in a paper published May 27 on the arXiv preprint server. Go to Source Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars, it is not expected to provide suitable conditions for the formation and hosting of a large planet. Go to Source Water is everywhere and comes in many forms: snow, sleet, hail, hoarfrost, and so on. However, despite water being so commonplace, scientists still do not fully understand the predominant physical process that occurs when water transforms from liquid to solid. Go to Source The challenge in the search for habitable worlds is clear. We need to be able to identify habitable worlds and distinguish between biotic and abiotic processes. Ideally, scientists would do this on entire populations of exoplanets rather than on a case-by-case basis. Exoplanets’ natural thermostats might provide a way of doing this. Go to Source […] Mars has received considerable attention in the past few decades, thanks to the many robotic missions exploring it to learn more about its past. NASA and China plan to send astronauts/taikonauts there in the coming decades, and commercial space companies like SpaceX hope to send passengers there sooner. This presents several significant challenges, one of […] Resonantly tunable quantum cascade lasers (QCLs) are high-performance laser light sources for a wide range of spectroscopy applications in the mid-infrared (MIR) range. Their high brilliance enables minimal measurement times for more precise and efficient characterization processes and can be used, for example, in chemical and pharmaceutical industries, medicine or security technology. Until now, however, […] The astronomical records of imperial China are some of the most comprehensive archives in the history of science, spanning over two millennia, from 221 BC to 1911 AD, and providing detailed insight into phenomena ranging from comets to the rate of rotation of Earth. Go to Source Across the cosmos, many stars can be found in pairs, gracefully circling one another. Yet one of the most dramatic pairings occurs between two orbiting black holes, formed after their massive progenitor stars exploded in supernova blasts. If these black holes lie close enough together, they will ultimately collide and form an even more massive […] No image is infinitely sharp. For 150 years, it has been known that no matter how ingeniously you build a microscope or a camera, there are always fundamental resolution limits that cannot be exceeded in principle. The position of a particle can never be measured with infinite precision; a certain amount of blurring is unavoidable. […] Ninth Circuit reverses qualified immunity for LAPD Officer Toni McBride, allowing a fatal shooting lawsuit to proceed. Go to Source A team of solar physicists has released a new study shedding light on the fine-scale structure of the sun’s surface. Using the unparalleled power of the Daniel K. Inouye Solar Telescope, built and operated by the National Solar Observatory (NSO) on Maui, scientists have observed, for the first time ever in such high detail, ultra-narrow […] Final results from a long-running U.S.-based experiment announced Tuesday show a tiny particle continues to act strangely—but that’s still good news for the laws of physics as we know them. Go to Source The Sombrero galaxy has long had a place in astronomical history as an intriguing object. The first written record of this galaxy was noted in 1781, almost 250 years ago, by Pierre Méchain, a French astronomer and surveyor. Méchain was a longtime collaborator of Charles Messier, of the Messier catalog fame. Go to Source […] This NASA/ESA Hubble Space Telescope image features a luminous tangle of stars and dust called the barred spiral galaxy NGC 1385, located about 30 million light-years away. Hubble released an earlier image of NGC 1385, but the two images are notably different. Go to Source |
