NASA's Mars Reconnaissance Orbiter captured a striking image of a recent impact crater on Mars, revealing a dramatic blast zone and ejecta pattern, providing valuable insights into Martian surface changes and impact frequency.
Scientists have uncovered the process behind the Messinian Salinity Crisis, a geological event 5.5 million years ago that transformed the Mediterranean Sea into a massive salt basin, losing up to 70% of its water volume. This occurred in two phases: an initial salt deposition in the eastern Mediterranean and a rapid evaporative drawdown affecting the entire basin, causing significant sea-level drops. These findings, published in Nature Communications, enhance understanding of past geological phenomena and their global impacts.
Between 200-300 million years ago, Earth experienced a two-million-year-long rain shower known as the Carnian pluvial event, which occurred during the time of the Pangea supercontinent and the rise of dinosaurs. This event, caused by an enormous volcanic eruption, led to a significant increase in rainfall, ultimately benefiting the dinosaurs and contributing to the origins of modern terrestrial fauna.
