Moon: August 2017

As the public prepares for the upcoming eclipse, astronomers have released a striking new radar view of the Moon.

New evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon, generating a magnetic field that lasted at least 1 billion years longer than previously thought.

NASA Astronaut Randy Bresnik: "Gorgeous moon rise! Such great detail when seen from space. Next [New] moon marks #Eclipse2017. We'll be watching from the International Space Station."
