It's that time of year again! Professional and amateur photographers alike are flocking to submit their best images of people, places and nature to the National Geographic 2014 Photo Contest. Submit your entries before the Oct. 31 deadline and you'll have a chance at winning $10,000 and a trip to the Nat Geo headquarters in Washington, D.C.

Dozens of artists have already sent in photos, including Spencer Black, an Asheville-based photographer who shot this gorgeous long exposure image (above) of Blue Ghost fireflies putting on a show in Brevard, North Carolina. Along with his entry, titled "Searching for Love," Black writes that these insects "are unique because they stay lit and only hover about a foot off the ground."

Some more amazing images that have already been entered into the nature category can be viewed below, with captions written by the respective photographers. To learn how to submit your own photos, be sure to read the contest rules and FAQ first!
