Asteroid impacts+hydrogen = recipe for Mars life

A new study reveals asteroid impacts on ancient Mars could have produced key ingredients for life if the Martian atmosphere was rich in hydrogen. An early hydrogen-rich atmosphere on Mars could also explain how the planet remained habitable after its … Continue reading

Rain brings death in Mars-like Atacama desert

When rains fell on the arid Atacama Desert, it was reasonable to expect floral blooms to follow. Instead, the water brought death. An international team of planetary astrobiologists has found that after encountering never-before-seen rainfall three years ago at the … Continue reading
