That's according to a new study released today by researchers at Keele University in England. The researchers said these super-powerful blasts - caused by the death of a massive star - may have previously stripped our planet's atmosphere of its ozone, sparked acid rain and exposed life to harmful ultraviolet radiation from the sun. They believe a supernova explosio

🔹 Climate Change “There have been five major extinctions during the life of planet Earth; the Ordovician, Devonian, Permian, Triassic, and the Cretaceous. All previous extinctions were due to climate change, the cooling of the oceans, the eradication of sunlight from volcanic eruption, or asteroid impact. A majority of scientists now believe that we are well into the sixth mass extinction (Holocene) on Earth. However, the current cycle is due entirely to human impact upon the planet and is happ

Extinction is a natural and common part of Earth's history, with an estimated 99% of all species that have ever lived now extinct. Catastrophic events like volcanic eruptions, asteroid impacts, and climate change have driven mass extinctions, which have paved the way for new life forms to evolve. While extinction is the norm, the survival and evolution of some species, like humans, are notable exceptions. | Science Acumen
