Biology — it may literally be out of this world.
Nuclear-powered ‘tunnelbot’ could probe the depths of Europa’s oceans
Europa’s almost as cold as your ex’s heart, just as frozen.
Mars may yet hold life in salty subsurface waters
Mars may be more life-friendly than we thought.
Fossil fats reveal the ‘oldest macroscopic animal’ that lived 558 million years ago
Hey, grandpa!
It Is Possible Jupiter Could Support Life, Scientists Say
The chances of it happening are pretty slim though.
Ancient volcanism shows our emissions can trigger a mass marine extinction
Ancient volcanism offers a glimpse into the future effects of climate change.
The Earth had continental crust much earlier than thought — potentially life, too
The Earth’s ‘young’ phase might have been much shorter than we assume.
What if we’re not the first advanced civilization on Earth — How would we know?
This is not about conspiracy theories, but a legitimate scientific concern.
Mass extinctions don’t come out of the blue — and we’re seeing some of the signs today
An incoming mass extinction isn’t as hard to spot as we’d believed.
Silicon-based life on Earth? Only artificially, so far — but maybe natural on other planets
A team of researchers forced bacteria to create carbon-silicon bonds, and their experiment showcases why life on our planet chose carbon.
Meteorites carrying both water and organic compounds point to an ocean world “seeding life” in the universe
Why spread your seed across the Earth when you can spread it across space?
What Curiosity found on Mars are probably just crystals — not fossils
This is likely not our first brush with alien life.
The earliest life forms could be these 3.5-billion-year-old microbes
The amazing discovery suggests that alien life might actually be common.
New evidence indicates that life on Earth emerged almost 4 billion years ago
It’s as old as we can possibly find.
New fossil proves there was life on Earth hundreds of millions of years earlier than we’ve though
Not your everyday find.
All the ingredients for alien life: NASA finds hydrogen spewing out of Saturn’s icy moon, likely propelled from hydro-thermal vents
Both Enceladus and Europa seem capable of supporting alien life, according to a major NASA announcement.
If there’s any life in the Trappist-1 system it’s likely been planet-hopping, scientists say
Nothing like a good ol’ meteorite impact to kickstart life.
Earth-born methanogen bacteria species could survive in Mars’ crust, new study shows
Life can be surprisingly hardy.
Early life kept oxygen in check and stalled evolution for billions of years, model suggests
Evolution doesn’t always procrastinate. But when it does, it’s for 2 billion years.
A whole new branch of life could have evolved and died off on Earth 2,4 billion years ago
There’s no proof. But the conditions were right for it to happen.
