Peep these pics: National Geographic's 20 most spectacular photographs from 2017.

When a National Geographic photo editor calls your work "spectacular," you know you've done well.

On Dec. 12, National Geographic announced the winners of its 2017 Nature Photographer of the Year Contest.

Divided into four categories (landscapes, underwater, aerials, and wildlife) and selected from more than 11,000 entries, these winning images represent some of the most stunning, unforgettable, and, yes, spectacular visions of the natural world.

And, by the way, National Geographic has made all of these images available as wallpapers.

Check out this year's amazing winners below.

Wildlife, first place and the grand winner overall — Jayaprakash Joghee Bojan's "Face to Face in a River in Borneo"

Bojan's photograph was chosen for both the winner of the wildlife category and the best photograph overall. For his work, he received a tidy prize of $10,000 and a spread in the print magazine.

Orangutans don't normally like wading through rivers (especially rivers inhabited by crocodiles), but sometimes the choice is unavoidable. Bojan had heard of this male orangutan's rare behavior and spent a day and night sitting near a river in Indonesian Borneo's Tanjung Puting National Park in order to see it for himself. When the ape finally appeared, Bojan actually waded into the river to get this shot.

"Honestly, sometimes you just go blind when things like this happen," said Bojan in a press release. "You’re so caught up. You really don’t know what’s happening. You don’t feel the pain, you don’t feel the mosquito bites, you don’t feel the cold, because your mind is completely lost in what’s happening in front of you."

Thanks to Bojan, National Geographic, and all the other very talented photographers who entered this contest, we all have a chance to get lost in it too.

Climate change is happening because the earth is warming at an accelerated rate, a significant portion of that acceleration is due to human activity, and not taking measures to mitigate it will have disastrous consequences for life as we know it.

In other words: Earth is heating up, it's kinda our fault, and if we don't fix it, we're screwed.

This is the consensus of the vast majority of the world's scientists who study such things for a living. Case closed. End of story.

How do we know this to be true? Because pretty much every reputable scientific organization on the planet has examined and endorsed these conclusions. Thousands of climate studies have been done, and multiple peer-reviewed studies have been done on those studies, showing that somewhere between 84 and 97 percent of active climate science experts support these conclusions. In fact, the majority of those studies put the consensus well above 90%.

As a child, Dr. Sangeeta Bhatia's parents didn't ask her what she wanted to be when she grew up. Instead, her father would ask, "Are you going to be a doctor? Are you going to be an engineer? Or are you going to be an entrepreneur?"

Little did he know that she would successfully become all three: an award-winning biomedical and mechanical engineer who performs cutting-edge medical research and has started multiple companies.

Bhatia holds an M.D. from Harvard University, an M.S. in mechanical engineering from MIT, and a PhD in biomedical engineering from MIT. Bhatia, a Wilson professor of engineering at MIT, is currently serving as director of the Marble Center for Cancer Nanomedicine, where she's working on nanotechnology targeting enzymes in cancer cells. This would allow cancer screenings to be done with a simple urine test.

Bhatia owes much of her impressive career to her family. Her parents were refugees who met in graduate school in India; in fact, she says her mom was the first woman to earn an MBA in the country. The couple immigrated to the U.S. in the 1960s, started a family, and worked hard to give their two daughters the best opportunities.

"They made enormous sacrifices to pick a town with great public schools and really push us to excel the whole way," Bhatia says. "They really believed in us, but they expected excellence. The story I like to tell about my dad is like, if you brought home a 96 on a math test, the response would be, 'What'd you get wrong?'"

I live in a family with various food intolerances. Thankfully, none of them are super serious, but we are familiar with the challenges of finding alternatives to certain foods, constantly checking labels, and asking restaurants about their ingredients.

In our family, if someone accidentally eats something they shouldn't, it's mainly a bit of inconvenient discomfort. For those with truly life-threatening food allergies, the stakes are much higher.

I can't imagine the ongoing stress of deadly allergy, especially for parents trying to keep their little ones safe.

Amy Johnson

The first day of school can be both exciting and scary at the same time — especially if it's your first day ever, as was the case for a nervous four-year-old in Wisconsin. But with a little help from a kind bus driver, he was able to get over his fear.

Axel was "super excited" waiting for the bus in Augusta with his mom, Amy Johnson, until it came time to actually get on.

"He was all smiles when he saw me around the corner and I started to slow down and that's when you could see his face start to change," his bus driver, Isabel "Izzy" Lane, told WEAU.

The scared boy wouldn't get on the bus without help from his mom, so she picked him up and carried him aboard, trying to give him a pep talk.

"He started to cling to me and I told him, 'Buddy, you got this and will have so much fun!'" Johnson told Fox 7.
