There's nothing quite like an amazing photograph of a wild animal, captured in a moment as a wild animal is meant to be - free, primal and spectacular.
If nothing else, it reminds us of how small we are on this big planet, and that there is an entire world unfolding beyond our day to day lives.
Well, every year for the past 48 years, the National History Museum in London and BBC Wildlife have run an international contest that brings together the best nature photography from around the world.
It's called the Veolia Environnement Wildlife Photographer of the Year and this year's winners have been announced.
Here's a look at some of the photos.
Winner: "Bubble-jetting emperors" by Paul Nicklen (Canada). A blast of penguins from the depths of the Ross Sea, Antarctica
Runner-up: "Fluff-Up" John E Marriott (Canada). A raven squatting on a snow covered road in Jasper National Park, Alberta.
Winner: "Practice run" by Grégoire Bouguereau (France). A pack of cheetahs stalk a gazelle calf in the Serengeti National Park, Tanzania.
Winner: "Ice matters" by Anna Henly (U.K.). A polar bear spotted at 4am in October walking on a broken ice floes between Norway and the North Pole.
Commended: "Crouch, pause, action" by Joe Sulik (USA). A bobcat in Badlands National Park, South Dakota leaping in the hunt for prey.
Commended: "Relaxation" by Jasper Doest (Netherlands). This is a Japanese macaque keeping warm in a hot-spring pool in the dead of winter.
Winner: "Warning Night Light" by Larry Lynch (USA). An alligator in the Myakka River State Park in Sarasota, Florida just after sunset, which is reflecting in the gator's eyes.
This year, organizers received nearly 48,000 entries, which were judged by an international panel.
The winners - about 100 in all - are currently on display at the Natural History Museum in London until March of next year, before going on a world tour.
The contest even has categories for young photographers 10 years old and under.
"It amazes me to discover new and startling moments that have never been seen before," said Jim Brandenburg, chairman of the judging panel, in a recent press release.
