By now, you've probably seen images from last week's Mercury transit. We love this version, inspired and mysterious. The planet Mercury is seen in silhouette, lower left, as it transits across the face of the sun Monday, May 9, 2016 from NASA Headquarters in Washington, DC. Mercury passes between Earth and the sun only about 13 times a century, with the previous transit taking place in 2006. Happy #spaceSaturday folks!
