Almost 66 million years ago, an asteroid hit Earth – and changed our planet forever. From tsunamis to shockwaves, join us on a journey through time as we explore the science behind this cataclysmic event.

Contrary to popular imagery, massive volcanic eruptions or an asteroid impact may not have been the cause of the world’s first mass extinction. Rather, some […]

A new study suggests that Earth’s ongoing mass extinction episode is more severe than generally perceived. Rather than focusing on the complete extinction of entire species, researchers analysed the losses and declines of populations in a sample of 27 600 vertebrate species. Population declines and losses are often a prelude to species extinctions. Researchers also conducted a more in-depth analysis of population losses between 1900–2015 in 177 mammal species. The results reveal that rates of population loss and decline in vertebrates are extremely high, even in common “species of low concern”. The data indicates that, in addition to significant species extinction rates, the Earth is experiencing a huge episode of population decline and loss, which will have a significant effect on ecosystem functioning and services. The researchers warn that the window for effective action is closing rapidly and emphasise the need for an urgent response.

A new study suggests that dark matter from the galactic plane may have been what really killed the dinosaurs — and it may one day threaten us.

The sun, like many stars, may be a binary, meaning it could have a mass-extinction-causing 'brother.'

At least five similar die-offs have happened before, but this is the first in human history — and the first with human help.
