Enjoying Comet C/2020 F3 Neowise's spectacular trail over Salt Lake City, UT. The tail, otherwise known as the coma is the nebulous envelope around the nucleus of a comet formed when the comet passes close to the Sun on its highly elliptical orbit. The force exerted on the coma by the Sun's radiation pressure and solar wind causes an enormous tail to form, which points away from the Sun. Tuesday, July 14, 2020. (Photo by Kiffer Creveling)
