Mars in a Manger
Explanation: At opposition in late January, Mars shone very brightly in planet Earth's night sky, among the stars of the constellation Cancer the Crab . Since then the Red Planet has been fading, but still lingers in Cancer during April and May . In mid-April, Mars wandered remarkably close to Cancer's famous star cluster M44 , the Beehive Cluster. M44 is also known by an older name, Praesepe, Latin for cradle or manger. Captured in this 60 second time exposure made on April 14, a yellow-tinged Mars and M44 are near the center of the field, seemingly just beyond the reach of a pine tree. Of course, M44's stars are about 600 light-years away, while Mars was more like 600 light-seconds from Earth. The digital photograph was made with a camera mounted on a telescope tracking the stars through dark skies above a camp ground in Virginia, USA. During the exposure, passing car lights briefly illuminated the tree branches.
