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 ...

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 ...

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 ...

A mass extinction event is a term used to describe a large-scale event that wipes out species. It is usually not a short, one-time incident but rather something that occurs over thousands or millions ...

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 ...

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 ...

However, for extinctions caused by anthropogenic (human) impacts on the environment, there is some concern among scientists that more evolutionary history may be lost than in past extinction events.

But if there is one thing we’ve learned from the history of past mass extinctions, it is (with a nod to “Jurassic Park”): “Life finds a way.” The post The Rise and Fall of Dinosaurs, As Explained by ...

Extinction is inevitable. Expected. Almost all (99%) species that have ever existed have died out. Those disappearances have largely occurred at consistent background rates. But in the context of mass ...
