The Moon and two planets form an arc in the early morning sky tomorrow. Orange Mars is to the right of the Moon, with golden Saturn to the lower left of the Moon.
Mars is considered one of the best possible homes for microscopic life in the solar system. That’s mainly because Mars appears to have a fair amount of water. There’s frozen water in the polar ice caps, and buried below the surface. There’s water vapor in the atmosphere. And there’s evidence that liquid water once formed rivers and lakes on the surface. That raises hopes that some liquid water could pool below the surface today.
