Though scientists have identified exoplanets that share some similarities with Earth, such as being within a star’s habitable zone, none of these worlds have been found to support human life.

New research links supernova events to sudden Earth cooling episodes and ozone depletion, revealed by carbon-14 spikes in ...

You’ve heard it before: we’re well into the sixth mass extinction of life on earth. Only this time, unlike the other five big ones, humans are overwhelmingly the killers responsible.

"When nearby supernovas occur in the future, the radiation could have a pretty dramatic effect on human society." ...

The evolution of humans on Earth may not be entirely exceptional. That is because intelligent life is likely to form if certain planetary conditions are met, a new study suggests. This idea ...

By removing the pull of gravity, space has accelerated breakthroughs once thought impossible, reshaping medicine, ...

"We are arguing that intelligent life may not require a series of lucky breaks to exist. Humans didn't evolve 'early' or 'late' in Earth's history, but 'on time,' when the conditions were in place.

In fact, scientists predict that Earth will eventually undergo a drastic atmospheric shift—one that will drive most life, including humans, to extinction, marking the end of life on Earth as we ...

And, as we veer away from widespread ice, scientists weigh if humans have an evolutionary advantage to live through warmer temperatures than life before us. Over the past 540 million years, Earth ...

That our evolutionary loss of body hair is at the root of this behavior's origins and how it's changed over the hundreds of thousands of years of human existence. University of Warwick's Adriano R.
