Volcanic eruptions on the seafloor are mysterious, but new research provides fresh clues.
It looks like a broken barbeque brickette, but the newfound meteorite is a capsule of the Solar System's history that could reveal the secrets of the origin of life.
If the building blocks of life were present at the time that Earth was born, this could mean life is common in the universe.
Unlike our hellish neighbour Venus, Earth was far enough from the Sun for liquid water to form and create a more hospitable environment for life.
How ancient microbes survived in a world without oxygen has been a mystery. Scientists discovered a living microbial mat that uses arsenic instead of oxygen for photosynthesis and respiration.
We don't fully understand viruses, and we're still trying to understand life.
Scientists have for the first time created shown how the precursor to living cells could have formed around deep-sea hydrothermal vents.
Humans evolved through a series of highly unlikely events – so finding another intelligence like us would be like winning the lottery many times over.
Current plans for lunar exploration may end up destroying ancient, genetic samples from Earth that have ended up on the moon.
Genetic data has helped scientists develop new estimates for the origin and evolution of life on Earth.
New research suggests life on Earth became more diverse because of a change in biology related to stem cells, not just rising oxygen levels.
Dust can be instructive. The analysis of those collected around the comet 67P/Churyumov-Gerasimenko provided new information on the history of the solar system.
Tiny tubes and filaments of iron found in rocks in Canada turned out to be the remains of microbes from over 3.7 billion years ago.
New research suggests how asteroids may have helped create conditions for life on Earth. But we shouldn't get too carried away with the idea – yet.
New research suggests the "primordial soup" theory can't explain how living cells evolved to harness energy.
Scientists have uncovered genes they believe have been passed down from an ancestor organism that all life evolved from.
A new theory could explain why the key molecules of life - DNA and RNA - only come in one of two possible forms.
Life on Earth may have started with a bit of sunshine and showers, followed with a light breeze of laughing gas and a sprinkle of hydrogen cyanide.
Study suggests that comets and meteorites could have seeded planets beyond our own solar system with life.
Is this where it all began?
