Heat-trapping asteroid dust may have incinerated the dinosaurs within hours
Recent research suggests a previously underestimated factor in the Cretaceous-Paleogene extinction event: heat-trapping asteroid dust. Simulations indicate that within minutes of impact, fine dust particles rapidly dispersed throughout Earth’s atmosphere, effectively creating a global oven. This phenomenon may have caused catastrophic heating, potentially incinerating dinosaurs within hours—a far more immediate consequence than previously understood.

Different moon rocks tell different tales about a long-ago bombardment
Recent analysis of lunar samples reveals a more complex history of early bombardment than previously understood. Prior samples, notably those from the Apollo missions, suggest a dominant impact event shaped the Moon’s surface. However, newly examined farside samples offer a divergent narrative, indicating a broader range of impacts over time. This refined understanding necessitates a recalibration of models concerning the Moon’s formation and the early solar system.
