Video shows the driver swerving to hit a person riding a bicycle along the side of a road Go to Source Eta Carinae may be about to explode. But no one knows when—it may be next year, it may be 1 million years from now. Eta Carinae’s mass—about 100 times greater than our sun—makes it an excellent candidate for a full blown supernova. Go to Source Mars once hosted a lake larger than any on Earth. The broken-down and dried-up remnants of this ancient lakebed are shown here in amazing detail by ESA’s Mars Express. Go to Source A seismic shift occurred in astronomy during the Scientific Revolution, beginning with 16th-century polymath Copernicus and his proposal that the Earth revolved around the sun. By the 17th century, famed engineer and astronomer Galileo Galilei refined Copernicus’ heliocentric model using observations made with telescopes he built himself. However, it was not until Kepler’s observations that […] Magnetic fields are everywhere in our solar system. They originate from the sun, planets, and moons, and are carried throughout interplanetary space by solar wind. This is precisely why magnetometers—devices used to measure magnetic fields—are flown on almost all missions in space to benefit the Earth, planetary, and heliophysics science communities, and ultimately enrich knowledge […] An international team of astronomers have used a powerful array of radio telescopes to discover new insights about a magnetar that’s only a few hundred years old. By capturing precise measurements of the magnetar’s position and velocity, new clues emerge regarding its developmental path. Go to Source Shock experiments are widely used to understand the mechanical and electronic properties of matter under extreme conditions, like planetary impacts by meteorites. However, after the shock occurs, a clear description of the post-shock thermal state and its impacts on material properties is still lacking. Go to Source Metalens is a kind of optical metasurface composed of metaatoms for manipulating incoming light’s amplitude, phase, and polarization. Unlike traditional refractive lenses, metalens can modulate the wavefront from plane to spherical at an interface. It has garnered widespread attention due to its novel physical properties and promising potential applications. Go to Source […] It wasn’t nostalgia that brought Judy Cha, Ph.D. ’09, back to Cornell. Among the reasons she left Yale University and joined the Department of Materials Science and Engineering two years ago was the prospect of working with an old friend: Lena Kourkoutis, M.S. ’06, Ph.D. ’09. Go to Source Soon, data storage centers are expected to consume almost 10% of the world’s energy generation. This increase is, among other things, due to intrinsic limitations of the materials used—ferromagnets. Consequently, this problem has ignited a quest for faster and more energy-efficient materials. Go to Source In solar cells and light-emitting diodes, maintaining the excited state kinetics of molecules against annihilation is a race against time. These systems need to strike a careful balance between different processes that lead to loss of energy and those that lead to the desired outcome. Go to Source Our future energy may depend on high-temperature superconducting (HTS) wires. This technology’s ability to carry electricity without resistance at temperatures higher than those required by traditional superconductors could revolutionize the electric grid and even enable commercial nuclear fusion. Go to Source Quantum computing promises society-changing breakthroughs in drug development and tackling climate change, and on an unassuming English high street, the race to unleash the latest tech revolution is gathering pace. Go to Source Did you know that in Tibet and India alone, there are more than 160,000 documented cases of people, who after many years of spiritual preparation, manage to transform their physical body into a body of pure light/Energy? In order to attain a “Rainbow Body”, a person has to be able to liberate their body […] |
