Over two billion years from now, Earth will no longer be able to sustain life. A new study looks at how much life has ever existed and what this means for the discovery of new life-supporting planets.
Life seems to just mysteriously ‘emerge’ from non-living parts, such as elementary particles.
The question of how difficult it is for life to emerge is interesting – not least because it can shed some light on the likelihood of finding life on other planets.
Even in death, a tree helps others live.
The key to understanding why life is not explainable in current physics may be to reconsider our notions of time and information.
Life may be using quantum mechanics to its advantage.
Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
It seems we are pretty lucky to have gravity that is just right for life.
In 2021, searchers recovered a meteorite that fell over the UK just hours earlier. Scientists have now reconstructed its story.
As material objects, diaries give scholars an intimate look into their subjects’ lives, including handwriting and mementos. What if diaries in the future are nothing but insubstantial digital ghosts?
A new study shows indecisive people should go easier on themselves.
Some people seeking to influence public opinion about abortion rights claim the science is clear. It’s not, and that means abortion remains a political question – not a biological one.
Lightning strikes may have helped spark life on Earth, and may be continuing to help life start on other Earth-like planets.
NASA’s Mars 2020 mission has arrived and landed the Perseverance Rover on the red planet. The rover’s goal is to collect rock and soil samples to be brought back to Earth in the future.
News that Venus may harbor life has swept the globe. So how do we find out for sure? A planetary scientist explains what’s next.
The clouds of Venus may harbour alien life. But where else?
We don’t fully understand viruses, and we’re still trying to understand life.
NASA scientists have discovered a new planet orbiting around a nearby star that is in a habitable zone. But does this planet have liquid oceans that can support life?
Somewhere out there, just maybe, an alien – probably stranger looking than in our wildest imagination – might be pondering this very question.
