Earth’s Magnetic Field ‘Preserved Habitability’ at Two Key Points in Planet’s History

Earth’s magnetic field preserved the planet’s habitability at two key points in its history, scientists have said.

The images, taken by the rover’s Navigation Camera (Navcam) on July 17, offer the best view yet of such clouds captured by Curiosity. “It is…
