Exploding stars in near-solar space may have triggered at least two mass extinction events in Earth's history. An analysis of the frequency of supernova explosions in the Milky Way, led by ...

Supernova destroying planet, illustration. A rocky planet lies in the wake of its star, which has just gone supernova. The explosion shatters the planet. A complete census of massive stars in our part ...

Sharks might be the all time bullet-dodging champions. They’ve been around for about 450 million years, longer than trees, longer than the rings of Saturn, and longer than most of the other life on ...

At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts ...

The Silurian Period is characterised by a dynamic interplay between environmental stressors and biotic turnover, with extinction events and carbon isotope excursions (CIEs) representing pivotal ...

Mass extinction events represent intervals of abrupt, large‐scale loss of biodiversity that have repeatedly reshaped life on Earth. These crises are commonly linked to dramatic environmental ...

Everyone knows that dinosaurs are extinct, and most people have some idea about how it might have occurred. But the exact periods in history when it happened are less well known. Was it a single ...

Most people think of crocodilians as living fossils—stubbornly unchanged, prehistoric relics that have ruled the world's swampiest corners for millions of years. But their evolutionary history tells a ...

The term “mass extinction” conjures up apocalyptic images of the world coming to an end, but a massive event like this can be a much slower process than many people realize. By definition, a mass ...

Many of their descendants—modern birds—are currently threatened by extinction, with hundreds of species at risk due to human activity. This article explores the major extinction events that influenced ...
