The "Big Five" mass extinctions of the Phanerozoic Eon have long attracted significant attention from the geoscience community and the public. Among them, the Late Ordovician Mass Extinction (LOME ...

Instead, the team hypothesized a stellar explosion may have been a potential factor in the Late Devonian extinction event 372 million years ago and one at the end of the Late Ordovician 445 ...

A research team linked nearby stellar explosions to at least one, possibly two, mass die-offs after calculating the supernova rate of stars closest to the sun in the past 1 billion years.

Researchers suggest supernovas may have caused two major mass extinctions on Earth, possibly factors during the Late Devonian and Late Ordovician periods.
