Comet Lulin, the greenish streak at center-right in this photo, as it appeared Monday night. Lulin is peaking in visibility early this week—here the comet is spied through tree branches at Shenandoah National Park in Virginia. It will be tough to see Lulin with the unaided eye in brightly lighted venues, but a pair of binoculars should do the trick. Instructions on where to spot the comet in the sky can be found in our blog post here.
