Launched on Oct. 20, 2018, the joint ESA/JAXA BepiColombo mission has traveled for almost eight years, using a carefully planned but eventful sequence of planetary flybys and solar-electric propulsion to gradually approach its destination, Mercury. The mission is now entering the final stage of its journey to the smallest and innermost planet of our solar […] Astronomers have found that a nearby galaxy’s black hole is blasting out a far more powerful and hidden gas outflow than previously realized. Studying NGC 1068, a well-known galaxy with an actively feeding black hole at its center, researchers combined new infrared observations with existing data to map how the black hole’s energy is reshaping […] Most of our experience with the Search for Extraterrestrial Intelligence (SETI) has focused on capturing radio signals that alien species have sent out, whether intentionally or unintentionally. That creates a huge “synchronicity” problem—what if there aren’t any alien civilizations broadcasting radio signals now, but there were a billion years ago? The Milky Way is around […] Does gravity act equally on all particles in the universe, or are there differences between ordinary and exotic matter? Physics professor Anna Soter and her team at ETH Zurich and the Paul Scherrer Institute (PSI) in Villigen are investigating this question. “We have taken an important step toward carrying out an exciting experiment on this […] The officer spoke with the man before and after he fell to the ground across a bike lane and a lane of traffic, but left the scene; the man was killed by a hit-and-run driver Go to Source When JWST’s first science results started rolling in, it was a triumph for scientific vision and persistence. For years, the fate of the powerful space telescope was uncertain. It went way over budget, and for 25 years, troubling conversations accompanied its ongoing development. Several times, it seemed like it would be canceled, and in 2011, […] Choosing an orbit for a satellite always comes with trade-offs. Very low Earth orbit (VLEO), between 100–450 km (62–280 miles), has distinct advantages. Remote-sensing cameras can take better pictures, communications and radar require less power, and atmospheric drag automatically cleans up dead satellites. Go to Source A new study of nine nearby galaxies has shown that actively growing supermassive black holes may contribute to, rather than prevent, star formation in their host galaxies. Go to Source Before there was Earth, there was chemistry. In the unimaginable cold, dark clouds where stars and planets are born, carbon molecules assemble into more complex forms—starting a chemical journey that could eventually deliver some of life’s basic ingredients to young planets. There’s only one problem: These molecules need heat to form. At least that’s what […] In May 2024, Earth experienced its most intense geomagnetic storm since the Halloween storms of 2003. This “superstorm” filled night skies in many parts of the world with colorful aurorae, and it disrupted some infrastructure, such as GPS signals used by agricultural equipment. Go to Source How can we predict the way a real material, such as a polymer, responds mechanically over timescales ranging from the ultrafast motion of atoms to the slow deformations measured in a laboratory? This is a deceptively difficult problem. Go to Source Three Houston PD officers and a Texas DPS trooper opened fire on the man after he ignored repeated commands to drop the rifle and raised it toward them, according to police Go to Source Extremely short, intense light flashes are in high demand to investigate atoms, molecules and new materials. Free-electron lasers (FELs) produce these flashes. But around the world, beam time available at large-scale user facilities is in short supply, and waiting times are long. Go to Source The vast majority of modern quantum technologies—from quantum cryptography to the quantum internet to the quantum computer—rely on one essential element: the transmission of photons. Two qubits (two atoms, for example) exchange information: One qubit emits a photon, and the other qubit absorbs it. Go to Source Physicists at the University of Oxford have helped confirm that one of the strangest phenomena in physics—quantum entanglement—occurs even among some of the heaviest and most fleeting particles ever created. The discovery, made using the world’s most powerful particle collider at CERN, has been published in Physical Review Letters. Go to Source […] |
