NASA is inviting media and viewers around the world to see a relatively rare celestial event, with coverage of the Monday, May 9 transit of the sun by the planet Mercury. Media may view the event at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

A stunning digital model of Mercury unveils the planet's striking landscape, while other new maps provide a closer look at the shadowed northern pole and reveal the highest and lowest points on the closest planet to the sun.  

Built with data from NASA's MESSENGER mission that orbited Mercury for four years, the new maps offer a bounty of scientific insight, while also delivering an incredible view of the planet.  

This first-ever global digital-elevation model (DEM) of Mercury combines more than 10,000 images acquired by the spacecraft to take viewers across the wide-open spaces of the tiny world. The animation reveals the planet's highest and lowest points. The highest is found just south of Mercury's equator, sitting 2.78 miles (4.48 kilometers) above the average elevation of the planet.
