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.
