Detailed model suggests organic matter on Mars was formed from atmospheric formaldehyde
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually life. In their quest to answer the burning question about life on Mars.....»»
Arctic warming may fuel ice formation in clouds, observations suggest
The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate.....»»
