A megacomet glows in the dark in this long exposure image taken by an astrophotographer on June 18 ahead of its closest approach to Earth.

Comet C/2017 K2 (PANSTARRS), dubbed K2, will swing by our planet on Wednesday (July 13) almost twice as far from Earth as our planet is from the Sun. But the comet, which can be as much as 100 miles across, still spews enough dust to show in telescopes’ fields of view.
