Comet Garradd sails slowly past globular star cluster M92 in this stunning image from a skywatcher in California.

The comet approached M92 as it flew over the Hercules constellation. It passed within half a degree of M92 on the day the image was taken.

M92 is one of the brightest globular clusters in the sky, and can sometimes be seen with the naked eye from the northern hemisphere. It's located more than 27,000 light-years from Earth. (A light-year is the distance light travels in one year - about 6 trillion miles, or 10 trillion kilometers.)
