The Solar System, moving at a rapid pace of around 200 kilometres per second in relation to the Milky Way’s center, has traversed various regions of our galaxy during its extensive journey. According to research findings, approximately 14 million years ago, the Solar System ventured through the Orion star-forming complex, part of the larger Radcliffe Wave structure.
This vast wave-like structure, discovered in 2020, is composed of gas and dust and houses numerous star-forming regions such as the Orion complex, Perseus, and Taurus molecular clouds. Stretching nearly 9000 light-years within the Milky Way’s Orion arm, this structure significantly influenced the Solar System when it passed through it.
The denser environment of the Radcliffe Wave and the Orion complex compressed the Sun’s heliosphere, permitting more interstellar dust to enter the Solar System and impact Earth’s climate, leaving a lasting imprint on geological records. The deep connection between the Solar System’s passage through these regions and the Middle Miocene Disruption, a period of extinctions that occurred around the same time, raises intriguing possibilities.
Moreover, the influx of interstellar dust potentially introduced anomalies into Earth’s geological record and could have induced global cooling. This discovery sheds light on the intricate interplay between celestial events and our planet’s climate history, underscoring the need for further interdisciplinary research. As we delve deeper into understanding these cosmic phenomena, we uncover new layers of Earth’s historical interactions with the vast expanse of the cosmos, offering a broader perspective on the intricate dance between our planet, its climate, and the cosmos at large.
