The science fiction author Arthur C. Clarke selected his own seven wonders of the world in a BBC television series in 1997. The only astronomical object he included was SS 433. It had attracted attention already in the late 1970s due to its X-ray emission and was later discovered to be at the center of a gas nebula that is dubbed the manatee nebula due to its unique shape resembling these aquatic mammals. …read more […] Earth’s moon shrank more than 150 feet in circumference as its core gradually cooled over the last few hundred million years. In much the same way a grape wrinkles when it shrinks down to a raisin, the moon also develops creases as it shrinks. But unlike the flexible skin on a grape, the moon’s surface is brittle, causing faults to form where sections of crust push against one another. …read more […] The European Space Agency gave the green light to two missions on Thursday, one to detect ripples in spacetime called gravitational waves and another to probe the secrets of Earth’s closest neighboring planet Venus. …read more […] Sensing technology, integral to environmental monitoring, data acquisition, and precision data processing, is evolving rapidly. Researchers are at the forefront of developing swift, accessible, and cost-effective sensors. Among these innovations, cholesteric liquid crystals (CLCs) in stimulus-responsive photonic crystals exhibit exceptional promise. …read more […] Our understanding of the world relies greatly on our knowledge of its constituent materials and their interactions. Recent advances in materials science technologies have ratcheted up our ability to identify chemical substances and expanded possible applications. …read more […] Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed and simulated a new energy-efficient way to generate highly focused and finely controlled X-rays that are up to a thousand times more intense than those from traditional methods. The findings are published in the journal Light: Science & Applications. …read more […] Electrons that spin to the right and the left at the same time. Particles that change their states together, even though they are separated by enormous distances. Intriguing phenomena like these are completely commonplace in the world of quantum physics. Researchers at the TUM Garching campus are using them to build quantum computers, high-sensitivity sensors and the internet of the future. …read more […] An international research team has successfully conducted ultra-precise X-ray spectroscopic measurements of helium-like uranium. The team, which includes researchers from Friedrich Schiller University Jena and the Helmholtz Institute Jena (both in Germany), has achieved results demonstrating their success in disentangling and separately testing one-electron two-loop and two-electron quantum electrodynamic effects for extremely strong Coulomb fields of the heaviest nuclei for the first time. …read more […] Within almost every galaxy is a supermassive black hole. Millions, sometimes billions of solar masses are locked within an event horizon of space and time. They can power luminous quasars, drive star formation, and change the evolution of a galaxy. Because of their size and abundance, supermassive black holes must have formed early in cosmic history. But how early is still an unanswered question. It’s a focus of a recent study on the arXiv preprint server. …read more […] Mason Leist is working remotely—127 million light-years from Earth—on images of a supermassive black hole in his office at the UTSA Department of Physics and Astronomy. …read more […] The Geostationary Operational Environmental Satellite U (GOES-U), the fourth and final weather-observing and environmental monitoring satellite in NOAA’s GOES-R Series, is now in Florida. The satellite landed on Tuesday, Jan. 23, in a United States Air Force C-5M Super Galaxy cargo plane at the Launch and Landing Facility at NASA’s Kennedy Space Center. …read more […] A barred spiral galaxy and a lenticular galaxy come together to create this interacting pair known as Arp 140. The lenticular galaxy, NGC 274, is visible on the right side of this new NASA Hubble Space Telescope image, and the barred spiral, NGC 275, is at left. The twosome is located in the constellation Cetus. …read more […] The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable—and above all reliable—properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model. …read more […] A soap film with chemically distinct sides represents the latest breakthrough in research led by chemist Sylvestre Bonnet. This unique soap film, along with an innovative device capable of continuously producing new soap films, forms a crucial piece in the puzzle for the development of artificial photosynthesis. The study is published in Physical Review Letters. …read more […] Astronomers using the NASA/ESA Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in its atmosphere. At only approximately twice Earth’s diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy. …read more […] |
