Using historical Earth models, Cornell University scientists suggest that dinosaurs or large, complex life could exist on exoplanets with high oxygen levels, guided by identifiable “sunlight fingerprints”.

Scientists Uncover a Novel Energy Metabolism that Could Sustain Life on Extraterrestrial Planets
Scientists have stumbled upon a groundbreaking discovery that might hold the key to life beyond Earth. Let’s rewind to the late ’80s when a scientist doodled some calculations on paper. This scientist figured out that turning a chemical called phosphite into phosphate could release enough energy to power a tiny organism. Imagine this microorganism being […]

Microfossils Reveal Rise in Complexity of Life Linked to Oxygen Increase
Scientists have found clues in ancient rocks that suggest life on Earth became more complex at the same time oxygen levels increased in the atmosphere and oceans. The rocks contain tiny fossils called microfossils that are over 2.4 billion years old. By studying these microfossils, researchers learned that complex life may have evolved earlier than […]
