How did life begin on Earth? While scientists have theories, they don't yet fully understand the precise chemical steps that led to biology, or when the first primitive life forms appeared. But what ...

In 2023, NASA’s OSIRIS-REx spacecraft collected samples of 4.6-billion-year-old rocks from an asteroid called Bennu and brought them back to Earth. They found amino acids, the building blocks of ...

Scientists believe they’ve found evidence that life on Earth is over a billion years older than anyone believed was realistic. New research used machine learning to scan ancient meteorites and fossils ...

New research has found that amino acids, the building blocks of life, may have traveled to Earth on interstellar dust grains, potentially helping kickstart biology as we know it. In a recent study ...
