Earth's inner core slows down: New research unveils 70-year cycle
Researchers have confirmed that Earth's inner core, a solid metal ball spinning independently within our planet, has slowed down significantly. Seismic data reveals a 70-year cycle in its rotational speed. The findings, published in Nature, indicate a complex interplay of forces influencing the core's motion. While this slowdown may impact Earth's magnetic field, scientists continue to debate its broader implications. This article delves into the latest discoveries and ongoing research in understanding the mysterious inner core.
NASA captures detailed images of passing asteroids, enhancing insights on planetary defence
NASA's JPL recently used radar to capture images of two passing asteroids. Asteroid 2011 UL21, discovered by Catalina Sky Survey in 2011, passed safely at 4.1 million miles on June 27. It's nearly a mile wide and has a small moonlet orbiting it. Asteroid 2024 MK passed closer on June 29, at 184,000 miles, with angular features and surface details seen in radar scans. These observations aid planetary defense efforts, providing crucial data on NEOs and their characteristics.
