Moon-forming impactor as a source of Earth’s basal mantle anomalies Seismic images of Earth’s interior have uncovered large low-velocity provinces (LLVPs), enigmatic regions in the lower mantle. Researchers propose that these LLVPs might be remnants of Theia, a celestial body that collided with Earth, creating the Moon. Simulations suggest Theia’s mantle material integrated into Earth,…
Precessing jet nozzle connecting to a spinning black hole in M87 Scientists have studied the radio galaxy M87, providing insights into the intricate relationship between supermassive black holes and their relativistic jets. M87’s active galactic nucleus (AGN), a compact, energetic region at the galaxy’s core, emits various forms of radiation beyond what stars produce. The…
Observation of the effect of gravity on the motion of antimatter Einstein’s general theory of relativity, which describes gravity, has been highly successful in experimental tests. However, concepts like dark matter and dark energy suggest gaps in our understanding of the universe’s gravitational properties. Researchers are exploring gravity in unique settings, including with antimatter. A…
